Summary: The naphtalenediimide-triphenylamine monomer (NDI-TPA) was synthesized and used to form a thin polymer layer on the electrode surface via electropolymerization. The monomer contains four triphenylamine groups and forms a cross-linked multielectrochromic polymer that changes color during oxidation and reduction. The influence of temperature on the electrochemical and electrochromic properties of the polymer coating was investigated, showing that higher temperatures result in faster and more reversible electrochemical reactions, shorter response times, but also faster degradation of the polymer film.

Summary: The new polymer P(BDT-fPPD) showed distinct properties compared to P(BDT-tPPD), with higher bandgap energy, deeper HOMO level, and higher crystallinity but lower carrier mobility and power conversion efficiency. The differences were attributed to the differences in backbone curvature between the two polymers, impacting their overall performance in organic solar cells.

Summary: Nanotubular titanium oxide (NTO) doped with Ni was synthesized using two doping techniques, immersion in Ni salt solution and using an ethylene glycol-based fluoride electrolyte containing Ni2+ ions solution. The samples were analyzed using SEM, XRD, and photoelectrochemical methods. The Ni-doped NTO showed twice the photocatalytic activity compared to the undoped NTO, and the immersion technique led to a shift of the incident photon to converted electron spectra to the visible part of the spectrum.

Summary: In this study, we highlight the importance of C-60 and compact-TiO2 as electron transport layers in the performance of coevaporated n-i-p perovskite solar cells. We demonstrate that there is a synergistic effect between these layers in charge extraction and optimization of the C-60 layer is crucial for enhancing device performance. Moreover, we find that excessively thick C-60 layers can introduce additional charge transport resistance and hinder the fabrication of highly efficient perovskite solar cells.

Summary: In this study, a series of donor-acceptor-donor (D-A-D) type small molecules based on fluorene and diphenylethenyl enamine units were developed as hole transporting materials (HTMs) for perovskite solar cells. The incorporation of malononitrile acceptor units not only improved carrier transportation efficiency but also passivated defects through Pb-N interactions. The HTM V1359 achieved a higher power conversion efficiency of over 22% compared to spiro-OMeTAD under the same conditions, demonstrating that HTMs prepared via simplified synthetic routes are not only a cost-effective alternative to spiro-OMeTAD but also exhibit superior efficiency and stability than materials obtained through expensive cross-coupling methods.

Summary: Imidazole-based donor-acceptor materials exhibit polarity-controlled trade-off between short-wavelength (SW) emission and long-wavelength (LW) emission. By synthesizing and verifying imidazole-based donor-acceptor fluorophores with different electron-donating groups, it was found that certain compounds showed dual emission in solvents of varying polarity, while others only exhibited SW emission. DFT calculations and experimental results revealed the different origins of SW and LW emissions. This work provides a new approach for achieving concurrent SW and LW emission characteristics and offers insights for the design of panchromatic emitters for lighting and display applications.

Summary: To solve the toxicity issues related to lead-based halide perovskite solar cells, a lead-free double halide perovskite Cs2AgBiBr6 is proposed. However, the reduced rate of charge transfer affects the optoelectronic performance of double perovskites. By using interface engineering, a series of pyridine-based small molecules with different arms attached to the pyridine core are designed as hole-selective materials. The solar cells fabricated using Cs2AgBiBr6 as a light harvester and the designed hole-selective layer showed an unprecedented 2.9% power conversion efficiency. Our findings provide guidance for designing small molecules for electro-optical applications and developing lead-free perovskite materials for solar applications.

Summary: Laboratory illumination is strong enough to create a photostationary state (PSS) of amphiphilic azo-benzene compounds in water. The [cis]PSS/[trans]PSS ratios were observed to be 0.33-1.2 in D2O and 0.37-3.8 in dimethyl sulfoxide-d6. ortho-Fluoroazobenzene amphiphiles show higher cis-isomer concentration at equilibrium compared to non-fluorinated compounds due to differences in optical absorption profiles. The kinetics of isomerization were measured using UV-Vis spectroscopy and the ratio of trans-to-cis rates does not directly correlate with the observed PSS. The half-life for PSS formation is 40 minutes for fluorinated compounds and 80 minutes for non-fluorinated compounds.

Summary: This study designed an integrated structure of Cu2O@Au/Cu2O heterostructure particles, which achieved significantly enhanced photocatalytic performance by simultaneously considering the integrated structural characteristics and localized surface plasmon resonance (LSPR) effect. Experimental characterization and theoretical simulation confirmed the three-in-one synergy of the integrated heterostructure, including the LSPR effect of Au nanoparticles, the light scattering based on core-shell heterostructure, and the effective charge separation based on inter-embedded heterostructure. The concept of integrated heterostructure cooperated with LSPR effect provides a new strategy for designing future catalysts.

Summary: In this study, the recombination of separated ion-radical states (SIRS) in PAPh films was analyzed, and it was found that the contribution of X-SIRS recombination to total luminescence varies with different environments. It was also shown that the recombination of labile SIRS is independent of the nature of the atmosphere. The study theoretically substantiated that SIRS recombination can occur via the transfer of both positive and negative charges, and the efficiency of thermal activation of recombination processes depends on the ratio of radiant and conductive channels of energy transfer.

Summary: Bifunctional hybrids containing photochromic indolyl(thienyl) diarylethenes and an ionochromic rhodamine moiety connected by a dimethylene spacer were synthesized. These hybrids exhibit absorption at 450-455 nm and fluorescence at 560 nm in toluene. UV light triggers ring-closed non-fluorescent diarylethene formation, which can be reversed under visible light or in the dark. In the presence of H+ cation, a naked eye effect is observed with the opening of the rhodamine-spirolactam ring and a pink-crimson coloration at 561 nm accompanied by intense long-wavelength emission at 586 nm. This process is reversible by exposure to triethylamine, as confirmed by NMR experiments. The light-induced isomerizations and proton-induced transformations were explained using computational methods. Reversible switching of fluorescent properties can be achieved by light irradiation and proton.
