Anthracene-based compound, and preparation method therefor and use thereof as solar thermal fuel

Abstract

An anthracene-based compound, and a preparation method therefor and use thereof as a solar thermal fuel are provided. The anthracene-based compound according to the present invention can be converted into a dimer under 365 nm ultraviolet irradiation and store light energy into chemical energy, and can be subjected to a depolymerization reaction under 254 nm ultraviolet irradiation and release heat. That is, the anthracene-based solar thermal fuel can store or release photo-thermal energy through a reversible photodimerization/depolymerization reaction. In addition, the anthracene-based compound has the unique advantage of photoinduced reversible solid-to-liquid transition, which can achieve the simultaneous storage of photon energy and phase transition energy. The anthracene-based compound has a storage energy density of approximately 65 KJ/mol and a storage half-life of up to 60 days.
