摘要:
A compound for enhancing the light output of a chemiluminescent system and, in particular, a stabilized, triggerable 1,2-dioxetane, is obtained by reacting a polyvinylbenzyl halide and a bilinker with either a trisubstituted amine or trisubstituted phosphine. A fluorescent molecule may be attached to polymer along with the trisubstituted amine or trisubstituted phosphine. Also, the benzyl halide may be reacted with a π-electron donor, such as a vinyl naphthalene or vinylanthracene to form a co-polymer which is polymerizable with the trisubstituted amine and/or trisubstituted phosphine. By controlling the reaction parameters it is possible to obtain either a water-soluble or partial water soluble or insoluble compound crosslink polymer.
