Abstract
Methods of forming single source precursors (SSPs) include forming intermediate products having the empirical formula ½{L2N(μ-X)2M′X2}2, and reacting MER with the intermediate products to form SSPs of the formula L2N(μ-ER)2M′(ER)2, wherein L is a Lewis base, M is a Group IA atom, N is a Group IB atom, M′ is a Group IIIB atom, each E is a Group VIB atom, each X is a Group VIIA atom or a nitrate group, and each R group is an alkyl, aryl, vinyl, (per)fluoro alkyl, (per)fluoro aryl, silane, or carbamato group. Methods of forming polymeric or copolymeric SSPs include reacting at least one of HE1R1E1H and MER with one or more substances having the empirical formula L2N(μ-ER)2M′(ER)2 or L2N(μ-X)2M′(X)2 to form a polymeric or copolymeric SSP. New SSPs and intermediate products are formed by such methods.
