Abstract

Photoexcitation of a Zn(II)-trimesic acid based metal organic framework containing co-encapsulated Ru(II)tris(2,2′-bipyridine) (RuBpy) and Co(II)tris(2,2′-bipyridine) (CoBpy) results in inter-molecular electron transfer (ET) between the excited state of RuBpy (3MLCT) and the ground state CoBpy The rate of inter-cavity ET, kET, is found to be 3.7 × 106 s−1. Using the semi-classical Marcus equation and the observed rate constant, it is determined that ET occurs between RuBpy and CoBpy complexes located in adjacent cavities (∼19.6 Å).
