Benzo[1,2-d:4,5-d′]bis([1,2,3]thiadiazole)-4-carbonitrile

Molbank, 2023
Electron-withdrawing heterocyclic units are found in most organic optoelectronic materials. Benzo[1,2-d:4,5-d′]bis([1,2,3]thiadiazole) is an interesting new heterocyclic system, the chemical properties of which are much less studied than other fused ...

A New Spin on Photocatalysis: Vortex Fluidic‐Driven Photooxidations Enabled by Solution‐Processable Microporous Polymers

Chemistry – A European Journal, EarlyView.
Newly developed polymers with intrinsic microporosity (PIMs) were combined with benzo[c][1,2,5]thiadiazole (BTZ) to be used as visible light photocatalytic coatings on the Vortex Fluidic Device (VFD). The VFD's rapid rotation and continuous flow capabilities enhanced singlet oxygen and superoxide radical reactions, achieving a dramatic eightfold ...

Flavin Catalysts in Organic Synthesis

Angewandte Chemie, Volume 138, Issue 42, 12 October 2026.
Flavins and their congeners are potent catalysts for organic synthesis inspired by enzymatic transformations. In addition to catalysis in the flavin ground state via covalent intermediates, the excited singlet and triplet states unlock applications including photooxidation, photoreduction, and energy transfer via sensitization.

Benzo[c][1,2,5]Thiadiazole Linkers Enhance the Effectiveness of Cavity‐Containing Supramolecular Photocatalysts

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.

Reverse evolution of fluorine and side chains in bisisoindigo‐based copolymers enabling electron mobility exceeding 7 cm2·V−1·s−1

FlexMat, EarlyView.
Abstract We report the design and synthesis of a series of bisisoindigo‐based donor–acceptor (D–A) copolymers, P4F18, P4F10, P2F18, and P2F10. By reverse evolution of fluorine substitution and side‐chain structure, we effectively tuned the frontier molecular orbital energy levels, intermolecular interactions, molecular self‐assembly, and thus charge ...
