Abstract
A guideline for a stable π-extended Wurster type redox system is proposed and two new acceptor molecules having a pyrene π-system were prepared and structurally characterised. 3,8-Bis(3′,5′-di-tert-butylphenyl)-13,13,14,14-tetracyano-1,6-pyrenoquinodimethane gave an electron transfer complex with Mn(TPP) (H2TPP = m-tetraphenylporphyrin) containing a coordination bond.
