4-4-difluoro-4-bora-3a-4a-diaza-s-indacene and oxalyl-chloride

Herein, a novel long wavelength monostyryl BODIPY derivative (BDZ-1) has been synthesized by rational design and used to detect oxalyl chloride, a highly reactive and harmful chemical to humans and other living organisms, with high sensitivity and selectivity. The purple solution of BDZ-1 changed to pink color immediately upon the addition of oxalyl chloride and the weak red fluorescence changed to strong orange fluorescence simultaneously. In addition, the practicability of BDZ-1 was further explored by using a smartphone application, allowing the sensitive and selective on-site detection of oxalyl chloride.
