Summary: This study reports on the rheological properties of organic gels prepared from TATA and OPVOH molecules. It is found that TATA/PVC ternary gels generally exceed the Voigt upper limit, possibly due to a desolvation process occurring in PVC fibrils. Furthermore, the conducting properties strongly depend on the solvent type but are not significantly altered when PVC is present.

Summary: This study investigates the photoinduced energy and electron transfer processes between quaterthiophene (QTH) and squaraine (SQR) dye in hybrid aggregates. The results show that energy transfer from QTH aggregates to SQR aggregates occurs within 120 fs, while electron transfer occurs at timescales of 131.5 ps and 3.3 ns, leading to the formation of a long-lived charge-separated state for more than 8 ns.

Summary: In this study, a stimuli-responsive organic material, SQ-d, was synthesized and its controllable luminescence was demonstrated. The luminescence of SQ-d could be switched by different external stimuli and its behavior was found to be affected by the concentration of solvent vapor. The origins of the different luminescent phases were analyzed and two prototype applications of SQ-d were successfully demonstrated: information encryption and vapor sensing.

Summary: The recent discovery of glass-forming hybrid metal halide perovskite semiconductors presents new opportunities beyond photovoltaics and light emitters. The reversible switching between glassy and crystalline states allows for potential applications in memory, computing, photonics, metamaterials, and phase change energy storage. The kinetics of glass crystallization in a specific perovskite compound, (S)-(-)-1-(1-naphthyl)ethylammonium lead bromide, has been studied, revealing its activation energy and nucleation characteristics. These findings provide valuable insights for modeling and assessing glass crystallization in metal halide perovskites.

Summary: Nanostructured carbonaceous materials, such as CNTs, graphene, and activated carbon, exhibit excellent conductivity and larger surface area, which can significantly enhance the electrochemical performance of transition metals based pseudocapacitive materials. The study successfully prepared copper sulfide nanochips via the hydrothermal method and improved their electrical conductivity and capacitive properties by forming nanohybrids with conductive CNTs. The nanohybrid sample demonstrated enhanced capacitive ability, gravimetric capacitance, and cyclic-aptitude compared to the pristine cobalt sulfide sample, showing great potential for practical application in next-generation electrochemical devices.

Summary: Hybrid chemical vapor deposition (HCVD) is used to fabricate perovskite solar cells/modules (PSCs/PSMs) with the introduction of a passivation layer and a solvent, resulting in improved efficiency and stability. The oxygen loss of SnO2 in the HCVD process is mitigated by potassium sulfamate (H2KNO3S) while the uncoordinated Pb2+ in the perovskite film is passivated. N-methylpyrrolidone (NMP) is used as a solvent to dissolve PbI2 and lower the energy barrier for perovskite nucleation. The use of perovskite seeds further enhances crystal growth and grain size. The resulting solar cells and mini-modules exhibit high power conversion efficiency (PCE) and stable output performance, with excellent operational stability.

Summary: The reactivity of a (110) rutile titanium dioxide surface functionalized with different forms of dodecyl-phosphonic acid was studied under various pH conditions using Density Functional based Tight Binding theory. The functionalization of this surface is important for protection against external agents and for anchoring other molecules. The solvation-desolvation process and hydration energy of the acids play a key role in determining the interaction between the acid molecules and the surface in water. The formation of di-anionic acid species is favored by anchoring alkylphosphonic acid to the rutile.

Summary: Three new cationic cyclometalated iridium(III) complexes with different substituents have been synthesized and characterized. The electronic properties of these complexes have been tuned by changing the substituents on the ligands. The emission of all complexes arises from ligand-centered triplet states with different photoluminescence quantum yields.

Summary: A new azaborine ligand was synthesized and used as an alternative to common cyclometalating ligands to obtain neutral phosphorescent iridium(III) complexes. The azaborine ligand induces a larger band gap in the complexes and results in a blue-shifted emission wavelength compared to the naphthalene analogues.

The compound crystallizes in the monoclinic P21/c space group with intra- and intermolecular hydrogen-bonding interactions. Optical properties were determined by absorption and luminescence spectroscopy, while DFT calculations provided insights into the molecular structure and electronic properties. Molecular docking simulations predicted significant inhibition of enzyme activity, and ADMET analysis confirmed drug-likeness properties.

Summary: A molecular conjugate synthesized and characterized in acetonitrile consisted of a free-base diphenyl porphyrin chromophore (DPP) trans-linked to two N-acridinium units. The emission of both fluorophores is quenched in the array at room temperature due to ultrafast electron transfer occurring upon excitation of either the porphyrin or the acridinium moiety. At low temperature (77 K), the emission of the porphyrin is completely recovered and a photoinduced energy transfer from the acridinium to the porphyrin component is observed due to the inhibition of electron transfer.

Summary: A multi-responsive receptor consisting of two (acridinium-Zn(II) porphyrin) conjugates has been designed, showing eight states resulting from the cascade of recognition and responsive events. The binding constant between the receptor and a ditopic guest can be modulated by the addition of nucleophiles and oxidation of the porphyrin units. The acridinium/acridane conversion leads to a significant change in the photophysical properties, with a switch from electron to energy transfer processes. Interestingly, charge-transfer luminescence in the near-infrared has been observed for the bis(acridinium-Zn(II) porphyrin) receptor.

Summary: We conducted a joint experimental and theoretical study on the steady-state spectroscopy and time-resolved emission of the coumarin C153 dye in methanol. The lowest energy excited state of this molecule exhibits an intramolecular charge transfer, which results in significant shifts in the time-resolved emission spectra due to the methanol reorganization dynamics. By applying a novel computational protocol that combines the Ad-MD|gVH approach with nonequilibrium molecular dynamics simulations, we achieved accurate predictions of the transient emission spectral shapes, including both vibronic and solvent effects. The overall agreement between the calculated spectra and the experimental results demonstrates the effectiveness of our approach, although some deviations were found at low energies and in the sub-ps timescale due to fast solvent dynamics and experimental time resolution limitations.

Summary: High molecular weight, fully biobased random copolymers of 2,5-furandicarboxylic acid (2,5-FDCA) containing different amounts of (1R, 3S)-(+)-Camphoric Acid (CA) were successfully synthesized and characterized. The addition of camphoric co-units led to modulation of the properties such as thermal, structural, mechanical, and barrier properties. The improved properties were associated with enhanced interchain interactions.

Summary: One of the major bottlenecks in supramolecular polymerization of functional pi-systems is the lack of control over chain length and optical properties. This study demonstrates that by copolymerizing phenyleneethynylene (PE) and Bodipy (BODIPY) derivatives in different ratios, the spontaneous one-dimensional and two-dimensional polymerization processes can be controlled, leading to unique structures with controlled aspect ratio.
