A boron–dibenzopyrromethene dye with a pinacolboryl group has been newly synthesized for the use as a reaction-based chemosensor. A TLC plate coated by the dye enables us to detect H2O2 vapor visually.

Hexylthiophene-conjugated boron-dibenzopyrromethenes with benzo[1,3,2]oxazaborinine rings, 1, that absorb near-infrared light with relatively high molecular extinction coefficients have been synthesized. The incorporation of 3-hexylthiophene-conjugated dye 1a at a blend ratio of 5 wt % into a polymeric solar cell based on a P3HT/indene-C-70 bisadduct (IC(70)BA) bulk heterojunction structure Improved power conversion efficiency from 3.7 to 4.3%. The present work suggests that well-defined near-infrared absorbing BODIPY analogues can potentially be used as photosensitizers in polymeric solar cells.
