Long-lived charge separation in a rigid pentiptycene bis(crown ether)–Li+C60 host–guest complex

Abstract

We report long-lived charge separation in a highly rigid host–guest complex of pentiptycene bis(crown ether) and Li+@C60, in which the pentiptycene framework is actively involved as an electron donor in a photoinduced electron-transfer process to the excited states of Li+@C60 through a rigid distance in the complex. © The Royal Society of Chemistry 2014.
