摘要
A sulfanylhexanol coupling agent is crucial for the preparation of GaAs-poly-(methyl methacrylate) (PMMA) hybrids by surface-initiated atom-transfer radical polymerization (ATRP) of methyl methacrylate (see scheme) as it passivates the GaAs surface and also immobilizes the ATRP initiator. The surface states of GaAs are not significantly affected by the ATRP process. © 2005 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.
