Summary: In this study, a stable P1 phase Sn-Ge mixed structure (CsSn0.5Ge0.5I3) with an appropriate band gap value of 1.19 eV was discovered, showing unique structural stability and physics properties. The thermodynamic stability of this mixed structure and its native defects under different growth conditions were investigated. The calculation of light absorption confirmed that the P1 phase has a higher light absorption coefficient than that of MAPbI3, indicating excellent light absorption. This work not only provides theoretical guidance for understanding the structural stability of Sn-Ge mixed perovskites, but also offers a useful approach to modulate the stability and optoelectronic properties of Ge-based perovskites through alloy engineering.

Summary: Based on the classical Schiff base reaction, a fluorescent probe PAI was designed and synthesized through structural modification by introducing Schiff base structure to pyrene unit. The synthesized PAI was characterized by FT-IR, 1H NMR, 13C NMR, and HRMS. PAI is a turn-on probe with high selectivity for specific recognition of Al3+ ion, and has a lower limit of detection compared to many other reported probes. The addition of Al3+ ion breaks the carbon-nitrogen double bond of Schiff base in PAI, resulting in a product without PET property and exhibiting enhanced fluorescence and blue color. PAI can also recognize Al3+ ion through test papers, which is beneficial for future research on Al3+ ion sensing.

Summary: Two bis-(Nitrogen-Heterocyclic Carbene, NHC) derivatives, 1, 3-bis[1-(quinolin-8-yl)-imidazolium-3-yl)]-benzene bis-hexafluorophosphate ( 2a ) and 2, 5-bis[1-(quinolin-8-yl)-imidazolium-3-yl)]-pyridine bis-hexafluorophosphate ( 2b ), were synthesized and characterized. The bis-NHC 2a showed excellent fluorescence chemo-sensor properties for selectively recognizing Al3+ ion in aqueous-organic media. The pyridine analogue molecule 2b did not exhibit selective recognition for most metal ions but showed fluorescence enhancement. Job's plot analysis and 1HNMR spectroscopy titrations suggested a 1:1 binding ratio and strong supramolecular interaction between Al3+ ion and the carbonic hydrogen and quinoline nitrogen. The detection limit for Al3+ ion was calculated to be 0.32 mu M. The practical application in tap water samples demonstrated the potential applications of bis-NHC 2a in complicated environments.

Summary: This study investigated the microstructure, optical properties, and crystallization kinetics of N-doped Cr2Ge2Te6 (NCrGT) phase change materials (PCMs). The NCrGT films exhibited a decrease in reflectance upon crystallization, and the N dopants accelerated the crystallization speed of CrGT. Laser irradiation could induce a reversible phase transition in the crystallized spots on the NCrGT films, indicating a lower thermal cost. The faster crystallization speed of NCrGT films resulted from their shorter incubation time and simplified crystallization process.

Summary: To obtain long-lived charge separated (CS) states in electron donor-acceptor dyads, a series of AQ-PTZ dyads with adamantane as the linker were synthesized. UV-vis absorption spectra showed no electronic interaction between AQ and PTZ units at the ground state, but CT emission bands were observed. Nanosecond transient absorption showed the population of (3)AQ and formation of (CS)-C-3 states in different solvents. Similarly, femtosecond transient absorption spectra demonstrated the formation of (3)AQ and (CS)-C-3 states with varying lifetimes. Time-resolved electron paramagnetic resonance (TREPR) spectra revealed the presence of radical ion pairs in AQ-PTZ and AQ-PTZ-M, while only (3)AQ state was observed in dyads with the oxidized PTZ unit.

Summary: A series of compact coumarin-anthracene donor-acceptor dyads were synthesized to investigate the relationship between molecular configuration, electronic coupling, and intersystem crossing (ISC) efficiency. The results showed that the orthogonal geometry of the dyads was beneficial to the spin-orbit charge transfer ISC (SOCT-ISC) mechanism. Singlet oxygen quantum yields were solvent polarity-dependent, and the orthogonal dyads exhibited higher yields compared to the coplanar dyad. Transient absorption spectra revealed different localized and delocalized triplet states in the dyads, with varied lifetimes. Time-resolved electron paramagnetic resonance (TREPR) spectra confirmed the involvement of the SOCT-ISC mechanism in orthogonal dyads, while both SOCT-ISC and spin-orbit ISC (SO-ISC) mechanisms contributed to the triplet state formation in the coplanar dyad. The electron spin polarization (ESP) pattern of the triplet states depended on not only the molecular geometry but also the electron donor and acceptor structure.

Summary: We synthesized a N boolean AND N Pt(II) bisacetylide complex with strong absorption of visible light (molar absorption coefficients epsilon=6.7x10(4) M-1 cm(-1) at 570 nm) and high singlet oxygen quantum yield (phi(Delta) = 78% ). The complex exhibits an intersystem crossing (ISC) of 81.8 ps and a triplet excited state lifetime of 7.6 μs. Density functional theory (DFT) calculations revealed that the S-1 and T-1 states are mainly localized on the perylenemonoimide (PMI) ligands, with noticeable involvement of the Pt(II) center. The complex acts as a triplet photosensitizer to generate delayed fluorescence with perylenebisimide (PBI) via triplet-triplet energy transfer (TTET) and triplet-triplet annihilation (TTA), resulting in a delayed fluorescence lifetime of 52.5 μs under the experimental conditions.

Summary: Porphyrins are highly adaptable materials for organic photovoltaics due to their adjustable functional groups. In this study, two porphyrin-based small molecule donors, IDT-2TPE and TPE, were synthesized. The device based on the IDT-2TPE donor and IDTCR nonfullerene acceptor showed a broad photoelectron response up to 1000 nm and a power conversion efficiency of 10.41%, while the device based on the TPE donor and IDTCR acceptor had a much lower efficiency of 4.22%. The improved performance of the IDT-2TPE/IDTCR device was attributed to its higher photocurrent generation and more favorable surface morphology with elevated charge carrier mobilities.

Summary: A series of electron donor-acceptor dyads were prepared to study the TADF properties. The photophysical properties of the dyads were tuned by changing the electron-donating and the electron-withdrawing capability of the PTZ and NI moieties. TADF was observed for the dyads containing the native PTZ unit, and the prompt and delayed fluorescence lifetimes changed with different aryl substituents on the imide part.

Summary: Bodipy (BDP)-perylenebisimide (PBI) donor-acceptor dyads/triad were synthesized to investigate the spin-orbit charge-transfer intersystem crossing (SOCT-ISC). Different quantum yields of singlet oxygen were observed for the dyads/triad, and various processes including FRET, CS, CR, and TTET were observed in the excited state dynamics. Time-resolved electron paramagnetic resonance spectroscopy revealed the involvement of both radical pair ISC and SOCT-ISC in the intersystem crossing. The triad BDP-PBI-2 showed an unusual electron spin polarization pattern of (e, e, e, e, e, e) in the triplet state formed via the RP ISC mechanism.

Summary: In this study, a series of dyads based on naphthalimide (NI) and phenothiazine (PTZ) were prepared to prolong the charge separation (CS) state lifetime by exploiting the electron spin control effect. The electron coupling magnitude was tuned by conformational restriction exerted by the methyl groups on the phenyl linker. Unlike previously reported analogues, these dyads exhibited a significant CS emission band and thermally activated delayed fluorescence (TADF). Nanosecond transient absorption spectroscopy revealed different states in different solvents, confirming the spin-vibronic coupling theoretical model. Femtosecond transient absorption spectroscopy indicated charge separation in both nonpolar and polar solvents, with varying time constants. Time-resolved electron paramagnetic resonance (TREPR) spectra supported the existence of (NI)-N-3* and CS states in the dyads upon photoexcitation. The electron spin-spin dipole interaction magnitude suggested the contribution of electron spin control to the long CS-state lifetime.

Summary: We synthesized a series of amino-substituted 9,10-anthraquinone derivatives to investigate their photophysical properties, particularly the intersystem crossing (ISC) efficiency and the triplet excited states. Monoamino-substituted derivatives exhibited a red-shifted absorption band at 509 nm compared to chloro-anthraquinone derivatives (lambda(abs) = 340 nm). Interestingly, additional amino substituents on the anthraquinone chromophore, i.e. diamino-substituted derivatives, did not induce further red-shifting of the absorption band. Only diamino derivatives showed decent ISC efficiency (singlet oxygen quantum yield, phi(Delta), up to 33.3%), while monoamino derivatives exhibited negligible phi(Delta) values. Nanosecond transient absorption spectra confirmed the formation of a triplet excited state with a lifetime of approximately 2.5 mu s. This short triplet excited state lifetime was attributed to the n-pi* character of the T-1 states in the diamino-substituted derivatives, as supported by DFT computations. We demonstrated that bisamino-substituted anthraquinones can serve as efficient photoinitiators for photopolymerization of alkene monomers, whereas derivatives with poor ISC capability showed minimal photopolymerization effects. The mechanism likely involves hydrogen abstraction by the photoinitiators in their triplet excited states. These findings suggest that compounds exhibiting efficient ISC and T-1 states with n-pi* character could be developed as efficient photoinitiators for radical polymerization of alkene monomers.

Summary: To investigate the relationship between twisted pi-conjugation framework and efficacy of intersystem crossing (ISC), a study on a distorted N,N,O,O-boron-chelated Bodipy derivative was conducted. Surprisingly, this chromophore exhibited high fluorescence and inefficient ISC. It was attributed to a large singlet-triplet energy gap. The introduction of an anthryl unit increased ISC yield, possibly due to the presence of a T2 state with similar energy to the S1 state.

It was found that the presence of the 3LE state sharing a similar energy with the CT states is critical for the occurrence of TADF.
