Abstract

The invention discloses a structure and a preparation method of a truxene-based star-like compound (TBP-C60). The preparation method is implemented by the following steps: by taking 7,12-dibromo-truxene-aldehyde derivative as a raw material and taking tetrahydrofuran as a solvent, performing Suzuki reaction on the raw material, the solvent and a BODIPY borate derivative under the catalysis action of tetra(triphenylphosphine) palladium, thus obtaining a truxene-BODIPY binary system compound TB; then by taking the TB and a porphyrin borate derivative as raw materials, performing reaction under the catalysis action of the tetra(triphenylphosphine) palladium, thus obtaining a BODIPY-truxene-porphyrin ternary system compound TBP; then performing cycloaddition reaction on the TBP, sarcosine and fullerene through 1,3-dipole, thus obtaining the star-like compound TBP-C60 in which the truxene is used as a core and the porphyrin, the BODIPY and the fullerene are used as arms. The preparation method of the star-like compound is simple, mild in reaction condition and easy and convenient to operate, shows excellent energy transfer efficiency and high heat stability and can be used for a light absorption antenna, a solar panel, light-simulated biological photosynthesis and other aspects.
