Used as a rigid, linear ditopic carboxylic acid linker for the construction of metal-organic frameworks (MOFs), particularly luminescent/fluorescent frameworks for photocatalysis, selective sensing (e.g., L-histidine, TNP, metal ions) and gas adsorption. Also employed as a key building block in organic optoelectronics, including donor-acceptor (D-A) conjugated molecules, organic solar cells and luminescent materials, and as an intermediate for other benzo[c][1,2,5]thiadiazole-based functional molecules.
