METHOD OF QUENCHING ELECTRONIC EXCITATION OF CHROMOPHORE-CONTAINING ORGANIC MOLECULES IN PHOTOACTIVE COMPOSITIONS

摘要

A method of quenching fluorescence of a naphthalate polyester that is subjected to UV- radiation in an amount sufficient to cause the naphthalate polyester to reach an excited state and fluoresce, comprising adding to the naphthalate polyester a fluorescence quenching amount of a compound of formula (1) wherein R1 is an alkoxy, R2 is an organic linker, k is either zero or one, / is either zero or one, wherein the sum of k+l is one, and m is an integer in a range from zero to about twenty
