Abstract
Insoluble platinum double salts were crystallized by a novel method involving a solid-liquid interface. The platinum complexes included Magnus Green Salt, MGS ([Pt(NH)3)4]2+ [PtCl4]2−) and PBC ([Pt(bpy)2]2+[Pt(CN)4]2−). The crystallization and molecular ordering of MGS and PBC on a Nafion membrane were achieved by controlling the diffusion of the cation and anion components to the solid-liquid interface. The electrical conductivity of the MGS film on Nafion was greatly augmented by oxidizing the polynuclear complex. A device consisting of the PBC film on Nafion, methyl viologen, and triethanolamine displayed photoelectrochromism.
