Effects of Biotin on a Fluorescein‐Based Photosensitizer Revealed by Multiscale Computational Modeling

Chemistry – A European Journal, EarlyView.
Biotinylation of a fluorescein‐based photosensitizer enhances its performance in PDT through a synergistic dual action. In addition to Type II singlet oxygen generation common to both dyes, the biotinylated system induces stronger membrane perturbation and higher local accumulation in lipid membranes, associated with increased water permeability and ...

Thermally Activated Delayed Fluorescence: An Extended Study of Peripherally Substituted DMAC‐TRZ Analogues

Chemistry – A European Journal, EarlyView.
A comprehensive experimental and theoretical study is presented of a family of TADF dyes. Comparing the behavior of structurally related dyes, we uncover the subtle and somewhat unexpected role of conformational degrees of freedom associated with peripheral groups that affect the delicate interplay of excited states that governs spin–orbit coupling ...

Multi‐state Photoswitching in Thienoquinoid‐Based Fluorescent Trithiophenes

Chemistry – A European Journal, EarlyView.
A methine‐bridged trithiophene with a thienoquinoid core undergoes photoisomerization of both C═C bonds, affording three geometrical isomers in a ratio controlled by the irradiation wavelength. Despite full π‐conjugation, the system retains fluorescence, enabling wavelength‐addressable multi‐state switching with luminescent readout.

Multi‐Scale Investigation of Supramolecular Organogels Assembled From Pt(II)‐Salphen Complexes

Chemistry – A European Journal, EarlyView.
A family of Pt(II)‐salphen complexes with long alkyl chains is investigated as low‐molecular‐weight organogelators. Multi‐scale characterization of their supramolecular gels reveals how the chain length, Pt‐Pt interactions, and π–π stacking direct self‐assembly and tune gel mechanics.

β‐Ketonitrile‐Modified Prodan Derivatives as Large‐Stokes‐Shift Solvatochromic Fluorophores With Enhanced Brightness and Ratiometric Thermometric Response

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.
