Published: Feb. 5, 2020

Abstract Traditional photothermal therapy requires high‐intensity laser excitation for cancer treatments due to the low conversion efficiency (PCE) of agents (PTAs). PTAs with ultra‐high PCEs can decrease required excited light intensity, which allows safe and efficient in deep tissues. In this work, a PTA is synthesized high PCE 88.3% based on BODIPY scaffold, by introducing CF 3 “barrier‐free” rotor meso ‐position (tfm‐BDP). both ground state, moiety tfm‐BDP has no energy barrier rotation, allowing it efficiently dissipate absorbed (NIR) photons as heat. Importantly, barrier‐free rotation be maintained after encapsulating into polymeric nanoparticles (NPs). Thus, irradiation intensity (0.3 W cm −2 , 808 nm) lead complete tumor ablation tumor‐bearing mice intravenous injection NPs. This strategy “barrier‐free rotation” provides new platform future design PTT clinical treatment.
