Monophenylboryl aza-BODIPY with free rotation of the B-phenyl group for enhanced photothermal conversion†
Abstract
Owing to the efficient non-radiative relaxation by the free rotation of the B-phenyl moiety, monophenyl substituted aza-BODIPY on the boron centre with near-infrared absorption has high photothermal conversion efficiency, which is highly desirable for a photothermal therapy agent.
