摘要：

Easy as pi: The Ugi four-component reaction (4CR) gives access to a functional πsystem consisting of an electron donor and an electron acceptor (see figure; PT=phenothiazine, AQ=9,10-anthraquinone). Intramolecular photoinduced electron transfer generates charge-separated diradical ion pairs originating from the singlet and triplet excited states. Charge separation in the triplet species persists for more than 2ns. © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
