Studies of organic-inorganic solids possessing sensitive oligoarylene-vinylene chromophore-terminated phosphonates

Abstract

The syntheses of xerogels possessing a phosphonate group covalently linked to a silica matrix through a fluorescent carbon backbone are described. BET and fluorescent analyses showed different behaviors for closely related structures. Hydrolysis of Et and t-Bu phosphonates in the presence of sensitive π-conjugated anthryl chromophore is described. © 2002 Elsevier Science Ltd. All rights reserved.
