New Materials and Chemistry: Small Molecules – Great Progress

The chemical and physical properties of a series of metal carboxylates of type [LnMO2CR]and [LnMO2CCO2MLn] (M = Cu, Ag; L = 2-electron donor; R = single bonded organic group; n = 1, 2, 3) is discussed. Their use as precursors in metallization processes applying CVD, ALD, CCVD, spin-coating and ink-jet printing on different substrate materials is reported. In addition, the use of metal-organic [AgO2CCH2(OCH2CH2)nOCH3] and [(Ph3P)AuO2CCH2(OCH2CH2)nOCH3] (n = 1, 2, 3, …) for the generation and stabilization of silver and gold nanoparticles is envisaged. Colloids (Ag, Au, Fe3O4, …) are also available by using end-grafted ethylene glycol-functionalized polyamidoamine dendrimers. The usage of organometallic species including carbosilanes and silanes for the preparation of C/C- und C/C-SiC-based composite materials as well as Si-based ceramics is reported.
