Overview
Related Products

4,4'-(Benzo[c][1,2,5]thiadiazole-4,7-diyl)dibenzaldehyde (BTDBA), CAS number 914651-17-5, has a structure of two 4-formylphenyl function groups that are joined to a benzo[c][1,2,5]thiadiazole (BT) core at 4,4-positions.

Benzothiadiazole-based covalent organic framework with an imine linkage, BT-TAPT-COF, demonstrated high crystallinity, excellent chemical stability, and significant light absorption ability as a high-performance platform for efficient visible-light driven hydrogen evolution reaction (HER).

Fluorescent ultrathin covalent triazine framework (F-CTF-3) nanostructure, constructed by the introduction of electron-deficient building block 4,4′-(benzo[c][1,2,5]thiadiazole-4,7-diyl)dibenzaldehyde with an aggregation-caused quenching behaviour, exhibited high stability, high porosity, and high fluorescence performance. Featuring a rich electron-deficient unit in the pore channel, F-CTF-3 is an ideal platform for sensing electron-rich PAA molecules with low detection limits of 11.7 and 1.47 nM toward phenylamine (PA) and p-phenylenediamine (PDA), respectively.
