Synthesis and Spectroscopic Characterization of Novel Thiourea-Bearing Photoactivatable NADPH Mimics Targeting NO Synthases

Abstract A new set of photoactivatable NADPH mimics bearing a thiourea linkage between a diarylbutadiene and an adenosine moiety functionalized by O-carboxymethyl groups has been designed and synthesized in a convergent strategy. These compounds…

Circularly Polarized Luminescence and Circular Dichroism of Bichromophoric Difluoroboron‐β‐diketonates: Inversion and Enhanced Chirality Based on Spatial Arrangements and Self‐Assembly

We synthesized two bichromophoric difluoroboron-β-diketonates (DFB) connected in para and meta positions by using cyclohexane diamine as a chiral bridge (para and meta (R/S)-CyDFB). TD-DFT calculations revealed that the variation in connectivity of…

Is it possible to ”simply” predict the photoejection of a cation? Example of azacrown-substituted [(bpy)Re(CO) 3 L] + complexes

In the context of designing efficient photocontrolled ion-release systems, we propose a "simple" computational strategy able to predict the cation photoejection. Our strategy is based on TD-DFT calculations and the analysis of the charge transfer …

Novel D–A chromophores with condensed 1,2,4-triazine system simultaneously display thermally activated delayed fluorescence and crystallization-induced phosphorescence

A new triazine acceptor unit is prepared and investigated together with common donors in D–A materials. With carbazole donors, changes in environment are able to elicit highly varied delayed emission behaviour.

Mechanofluorochromic Difluoroboron <i>β</i> ‐Diketonates Based Polymer Composites: Toward Multi‐Stimuli Responsive Mechanical Stress Probes

Developing mechano-responsive fluorescent polymers that exhibit distinct responses to distinct mechanical stresses requires a careful design of the fluorophore in order to tune its interactions with the polymer. A series of mechanofluorochromic (MFC…
