Abstract
Spatial electronic communications of chromophores are both theoretically and practically fascinating. Despite intramolecular or intermolecular exciton coupling was observed in multichromophoric oligomers and J-aggregates, respectively, it is unusual that they both occur in the same molecule. Herein, ethene-bridged aza-BODIPY dimers with intramolecular exciton splitting have been developed. By encapsulating the dimer into F-127 polymer, J-type aggregated nanoparticles were produced, which showed obvious intermolecular exciton coupling and dramatically redshifted absorption and emission peaks at 936 and 1003 nm, respectively. The fabricated nanoagents have high photothermal conversion ability (η=60.3 %) and are ultra-photostable, leading to complete tumor ablation with 915 nm laser irradiation. This phototherapeutic nanoplatform through modulating both intra- and intermolecular exciton couplings is a valuable paradigm for developing photothermal agents for tumor treatment.
