附简介:
简介:高加力是一位理论与计算生物化学家,其研究重点是大分子系统的结构和性质,包括对蛋白质动力学和酶催化作用的理解。目前正在开展密度泛函量子理论的研究,将 Hohenberg 和 Kohn 关于单电子态(基态)的定理推广到薛定谔方程的所有电子态。
摘要:Triplet excited-state energy transfer (TEET) provides a versatile activation mode in photocatalysis, enabling enantioselective [2+2] photocycloadditions, deracemizations, and conformational isomerizations by directing substrates onto triplet surfaces where bond reorganization is facile. In this work, I will present a computational study of the activation mechanism for TEET from a lower energy state of the catalyst to a higher energy triplet of the substrate. I will discuss the theory and computational procedure of multistate density functional theory developed in my group for studying chemical and biological photochemical processes.
