Abstract

o-Hydroxybenzophenone (Hbp) chromophores were immobilized on 3-aminopropyl silica gel (SiO 2–NH 2) by a reaction of succinimidyl 4-(4-benzoyl-3-hydroxyphenoxy) butanoate (2a) and-undecanoate (2b) with SiO 2–NH 2 to produce microbeads 1a and 1b in 25 and 21% yield, respectively. The bond formation was confirmed by appearance of an absorption at 1550 cm− 1 due to the N–H bending of the amide bond in the IR spectra of 1a and 1b. ...
