Consider the coordination chemistry of actinides and propose a synthetic strategy for the preparation of a heterobimetallic complex containing both uranium and copper, which should exhibit favorable photophysical properties. Provide a detailed mechanism for the synthetic route and discuss the spectroscopic characterization techniques that could be used to verify the structure of the complex.
