Inspired by the electroless galvanic replacement (GR) process where a spontaneous redox reaction occurs between two metal species primarily due to the difference in the standard electrode potential of the metal/metal ion couples, a facile strategy is developed to fabricate hybrid materials of metal organic semiconducting materials. The GR of CuTCNQF 4 , a metal organic charge transfer complex with Ag + ion results in the formation of hybrids, wherein at low Ag + ion concentrations, a hybrid of Ag nanoparticles decorated on the surface of CuTCNQF 4 is obtained. In contrast, high Ag + ion concentrations show the formation of AgTCNQF 4 /CuTCNQF 4 hybrids with Ag nanoparticle decoration on the surface of the CuTCNQF 4 structures. While the GR reaction results in different hybrids depending on the concentration of Ag + ions and the availability of underlying Cu foil, we observe that the resulting hybrids have an influence on the catalytic and electrical properties. The outcomes presented in this work present a strong foundation for fabricating hybrid materials encompassing metal organic charge transfer complexes and exploring their properties for new biological, catalytic and electronic applications.
