Photo‐Switchable FRET‐Enabled Flexible Luminescent Films for Multilevel Optical Security
Carbon Energy, EarlyView.A light‐gated FRET composite integrates a Tb‐Phen donor and a spiropyran acceptor in a polyurethane matrix. Under 365 nm light, spiropyran is transformed into merocyanine, creating spectral overlap with Tb3+ emission and activating energy transfer. Visible light reverses the switch, restoring green emission and enabling reversible multilevel optical ...

Chemistry – A European Journal, EarlyView.Seven novel supramolecular photosensitizers based on benzo[c][1,2,5]thiadiazole (BTZ) tethered to calix[4]arene (C[4]) scaffolds are reported with facile, scalable, and selective syntheses. Their abilities to produce singlet oxygen have been tested through the photo‐oxidation of α‐terpinene.

Chemistry – A European Journal, EarlyView.We report a systematic study of β‐ketonitrile–modified Prodan‐type solvatochromic fluorophores. The β‐ketonitrile substitution induces marked bathochromic shifts in absorption and emission and significantly enhances fluorescence quantum yields in nonpolar solvents.

Chemistry – A European Journal, EarlyView.Understanding aromaticity has evolved from benzene‐centric concepts to a broad multidimensional framework spanning organic, inorganic, and excited‐state systems. This review highlights ambiguities between magnetic, electronic, geometric, and energetic descriptors, emphasizing the need for unified, multi‐criteria approaches.

Photostability of Cyanine Dyes and Its Correlation to Their Photothermal and Photodynamic Effects
Chemistry – A European Journal, EarlyView.Photostability (PS) of dyes is a crucial parameter for performance in biological applications, yet often underrated. Here PS of several cyanines is investigated. The method is carefully evaluated and designed as a general and easy tool to compare PS of NIR dyes.

Photochemical afterglow of single organic molecules with wide‐range tunable lifetime
PhotoMat, EarlyView., 2023 “All‐in‐one” strategy was used to achieve photochemical afterglow in single organic molecule, with second‐to‐hour range tunable lifetime by tailoring the electron‐withdrawing ability of substituents. Abstract Background Photochemical afterglow that relies on slow release of photons from the chemical energy stored by light pre‐irradiation has emerged as
