Porphyrin Donor and Tunable Push-Pull Acceptor Conjugates-Experimental Investigation of Marcus Theory

We report on a series of electron donor–acceptor conjugates incorporating a Zn II –porphyrin‐based electron donor and a variety of non‐conjugated rigid linkers connecting to push–pull chromophores as electron acceptors. The electron acceptors comprize multicyanobutadienes or extended tetracyanoquinodimethane analogues with first reduction potentials ranging from −1.67 to −0.23 V vs. Fc + /Fc in CH 2 Cl 2 , which are accessible through a...
