Charge Dynamics in A Donor–Acceptor Covalent Organic Framework with Periodically Ordered Bicontinuous Heterojunctions

Light works: Mechanistic insights into the photochemical events and charge dynamics of a donor–acceptor covalent organic framework were given by time-resolved transient absorption spectroscopy and time-resolved electron spin resonance spectroscopy (see picture). The organic framework triggers ultrafast electron transfer and enables long-distance charge delocalization and exceptional long-term charge separation.
