Phenothiazinyl primary amines were synthesized in moderate to excellent yields from cyano (oligo)phenothiazines by reduction with LiAlH4 in diethyl ether or with nBuNBH4 in dichloromethane. All representatives show first reversible oxidation waves, they are UV absorbing and dimers emit blue-green light upon UV excitation with substantial quantum yield.

Easy as pi: The Ugi four‐component reaction (4CR) gives access to a functional π system 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
