Carboxylic acid-terminated organosilanes

Carboxylic acid-terminated organosilanes were used in the early studies on chemically bonded glycopeptides to immobilize vancomycin and thiostrepton via then-amino groups, leading to the formation of stable amide bonds between antibiotics and modified silica [7]. In a typical reaction, 4 g of dry silica gel is slurried on 50 mL of dry toluene. Two grams of [l-(carbomethoxy)ethyl]methyldichlorosilane or [2-(carbomethoxy)ethyl]trichlorosilane is dissolved in 15 mL of dry toluene contained in a dropping flask. The organosilane solution is added dropwise over 30 min... [Pg.124]

This chapter describes chemical modification of various n-type TCO electrode surfaces with various organic molecules in which one end is a binding group (X—), the other end is a terminal group with a different functionality (e.g. permanent dipole moment) (—Y), and these two ends are linked by groups of alkyl chain and 7T-system as shown schematically in Fig. 2. Studies for formation of various organic monolayers with carboxylic and phosphonic acids as well as organosilanes... [Pg.6108]
