摘要
Abstract
To increase the surface concentration in the coating and enhance the UV absorption capacity of the benzophenones-type UV absorber, the fluorine-containing derivatives from UV-0 were designed.To investigate the influence of different substituent groups, and screen a new UV absorber, the structural and spectral properties of the title compounds were studied by using density functional theory (DFT)and time-dependent density functional theory (TD-DFT) at the B3LYP/6-31++G** level.The calculation results demonstrate that the conjugate effect between O17 and ring B and the UV absorption capacity may decrease with an increasing forked chain length, when the substituent group is connected through the ester bond.On the contrary, the UV absorption capacity in 230~290 nm and 310~400 nm may increase relatively little effected by the length of forked chain, when the substituent group is connected through the ether linkage.Considering the UV absorption capacity and the ability for surface enrichment, compound V is the best derivative.关键词
