How to Harness Electrochemical Mediators for Photocatalysis – A Systematic Approach Using the Phenanthro[9,10‐d]imidazole Framework as a Test Case

Von Wiley-VCH zur Verfügung gestellt

The mediator portfolio of electrosynthesis holds untapped potential for photocatalytic applications. A systematic approach toward harnessing electrochemical mediators for photocatalysis is presented using the phenanthroimidazole framework, a known electrocatalytic system, as a test case. As a result, a much broader platform becomes accessible that allows both oxidative and reductive transformations by choosing the type of energy input (light or electricity).


Abstract

In view of the frequently cited similarities between photo- and electrocatalysis, large overlaps are to be expected in terms of the mediators used. However, closer inspection reveals that the exchange of mediators is the exception rather than the rule. In this context, the mediator portfolio of electrosynthesis holds great potential for useful applications in photocatalysis (and vice versa). Herein, a systematic approach toward harnessing electrochemical mediators for photocatalysis is presented. Using the phenanthro[9,10-d]-imidazole framework (a known electrocatalytic system) as a test case, it is shown how systematic investigation and tuning of the mediator properties leads to application in photocatalysis. As a result, a much broader platform becomes accessible, one in which the redox potential in the ground and excited state can be adjusted by variation of the substituents to enable both oxidative and reductive transformations to occur simply by choosing the type of energy input (light or electricity).
