A molecular-module comprising of a surface-confined optically rich and redox active homobimetallic chromophore on siloxane-based templates, has been obtained and characterized via X-ray photoelectron spectroscopy, atomic force microscopy, UV–vis measurements, and cyclic voltammetry. The multimetallic system offers high order optical/redox “write-read” for viable chip-engineering. In fact, this system proposes a potential platform to save a high charge/information density of ∼3.6 × 1014 electrons/cm2 as a function of the applied potential. Moreover, the convenient synthetic pathway, and the manipulation of Ru2+/Ru3+ redox wave into multiple intermediate mixed valence redox states, are the significant advantages with respect to heterobimetallic analogs toward its integration in “multi-memory” systems. Notably, the module exhibits a high charge density storage capacity, is robust against a large no. of redox cycles and high temperatures.
