Light driven water oxidation performances of several Prussian blue analogues involving cobalt
ions have recently been investigated in the presence of a [Ru(bpy) 3]2+/persulfate system.1-3
Although cobalt hexacyanometalates stands forward due to their high catalytic activities ( a
quantum yield of ≤88%), one of the main drawbacks of the system is its low stability during
catalysis. Inspired by molecular dyads, herein, a step-by-step rational design of cyanide
based compounds with enhanced catalytic activities has been introduced. The photocatalytic
performance of these systems for light-driven water oxidation process will also be presented.
