The photoprotective capabilities of a family of compounds have been investigated. Their relaxation mechanisms have been explored by fluorescence and transient absorption measurements, and the minimum energy relaxation pathways were modeled by CASSCF/CASPT2 methods. This study demonstrates their excellent properties as sunscreens, and provides novel mechanistic insights for the rational design of new species.
对一类化合物的光保护能力进行了研究。通过荧光和瞬态吸收测量探索了它们的弛豫机制，并采用CASSCF/CASPT2方法对最低能量弛豫途径进行了建模。这项研究证明了它们作为防晒剂的优异性能，并为合理设计新物种提供了新的机理见解。
