Over the years, the use of molecular single source precursors (SSPs) has been an effective strategy to prepare binary and ternary nanoparticles.  By decomposing molecular SSPs containing all requisite elements, one can produce nanoparticles with controlled stoichiometry, size, and phase.  However, the same strategy is not always readily applicable to the preparation of quaternary and more complex compositions.  We have been interested in tuning nanoparticle properties such as bandgap by judicious control of the stoichiometry among a variety of component elements.  In this presentation, we will discuss the synthesis of complex molecular precursors designed for this purpose and their decomposition to prepare novel I-III-VI multinary nanoparticles such as CuInxGax-1S2 and AgxCux-1InS2.
