Study of photo-induced energy storage and heat release performances of anthracene-based long-chain molecular solar thermal fuels
摘要
Abstract
Anthracene,as a high value-added basic chemical raw material in coal tar,has a wide range of application prospects.Using anthracene from coal tar as the raw material,two kinds of anthracene-based molecular solar thermal(MOST)fuels with different alkyl chain lengths(ANT-1,ANT-2)were successfully prepared by chemical reaction based on the photodimerization/depolymerization of anthracene,and its photo-induced energy storage and heat release performances were studied,in order to realize its high value and diversified utilization.The structures of anthracene-based long-chain MOST fuels were characterized by FT-IR,1H NMR and HRMS,and the photodimerization/depolymerization performance,energy storage density and controllable heat release performance of the anthracene-based long-chain MOST fuels were studied by UV-Vis absorption spectroscopy and thermal analysis.The results show that compared with the energy storage density of anthracene and its derivatives(20 kJ/mol to 30 kJ/mol),the energy storage density of ANT-2 dimer can reach 89.6 kJ/mol,and the energy storage half-life can be extended to 60.96 d,and it exhibits good thermal and cyclic stability.Moreover,the heat released by ANT-2 dimer film triggered by UV light can increase its own temperature by 5.4℃,which has some potential for application in the field of intelligent temperature control.关键词
