Abstract

This experimental and theoretical study illustrates how phosphaalkenes, which are isolobal to alkenes, can utilize a variety of external triggers for molecular switching. The E/Z isomerization of a truxene-based phosphaalkene, i. e. TruxC=P-Mes* (Mes*=2,4,6-tris-t-butyl-benzene), is accomplished by irradiation, metal coordination, or deprotonation of the truxene core. The reversible and quantitative Z/E double bond isomerization by gold(I) coordination/decoordination of the phosphorous lone pair represents a novel fuelling strategy for molecular switches.

摘要

这项实验和理论研究表明，与烯烃等瓣的磷烯如何利用各种外部触发因素进行分子开关操作。基于均三苯的磷烯（即TruxC=P-Mes*，Mes* = 2,4,6-三叔丁基苯）的E/Z异构化可通过均三苯核心的辐照、金属配位或去质子化来实现。通过磷孤对的金（I）配位/去配位实现的可逆且定量的Z/E双键异构化代表了一种用于分子开关的新型供能策略。
