Noncrystalline L-Phenylalanine-Silica Hybrid Composite Materials for High Selective Reversed Phase Liquid Chromatography

Abstract

A review. The self-assembling properties of octadecylated L-phenylalanine derivs. are discussed. Four octadecylated L-phenylalanine derived polymerizable monomers are considered. The polymn./telomerization of all four monomers are done by both conventional radical polymn. followed by grafting on to inorg. silica particles ('grafting to' method) and also by controlled radical polymn. method ('grafting from' method) to prep. hybrid composite materials. One practical application of these composite materials for sepn. of toxic PAHs is also discussed for high selective reversed phase liq. chromatog. The chromatog. performance for the octadecyl L-phenylalanine derived hybrid composites prepd. by 'grafting to' and 'grafting from' method is also compared. [on SciFinder(R)]
