First Time

We disclose for the first time that the singlet excited state (1PS*) of BODIPY rather than triplet excited state (3PS*) can drive C–H bond activation to form C–C and C–P bonds smoothly upon irradiation by visible light.

Dehydrogenative Coupling

C–H bond activation and dehydrogenative coupling reactions have always been significant approaches to construct microscopic nanostructures on surfaces. By using scanning tunneling microscopy/spectroscopy (STM/STS) and non-contact atomic force microscopy (nc-AFM)...
