摘要：

The film-forming behavior of nanosized metallic clusters composed of 55 gold atoms, isolated from each other by a thin organic ligand shell with a total size of 2.1 nm in diameter, was investigated by pressure-area isotherms, constant pressure relaxation and Brewster angle microscopy (BAM) at the air-water interface. The monolayer was transferred onto various substrates by using the Langmuir-Blodgett (LB) technique. Scanning tunneling microscopy (STM) on the LB films reveals a partially close packing of the clusters. (C) 1998 Elsevier Science S.A. All rights reserved.
