Monolayer-protected clusters (MPCs) are used to prepare solid, continuous metal films containing a single white metal or an alloy thereof. MPCs consist of nanoscopic metal cores coated with monolayers of thiolate ligands. In one method, multilayer films of carboxylatefunctionalized alkanethiolate MPCs are assembled using Cu2+ coordinative bridges. The MPC film can be thermally decomposed at moderate temperature (
