Change of electron-transfer path-selectivity in a triad by F–-coordination at a boronate-ester bridge
Abstract
In a triad comprising of a zinc porphyrin donor (ZP) appended to a naphthalene-1,8∶4,5-tetracarboxylic diimide (NI) and a pyromellitic diimide (PI) through a boronate ester and an acetal bridge, respectively, F–-coordination at the boronate bridge induced clear switching of the electron-transfer path from 1ZP* → NI to 1ZP* → PI.
