WATER-SOLUBLE CONJUGATED POLYMER COMPOUND WITH HYDROPHILICITY BY INTRODUCING SULFONIC ACID OR SULFONIC SALT IONIC GROUPS, AND A SELECTIVELY DETECTING METHOD OF CYSTEINE BY USING THE SAME

摘要

PURPOSE: A water-soluble conjugated polymer is provided to be used a detection material for cysteine in a thin film and to have high selectivity to cysteine, thereby being used for a chemical sensor and bio sensor.;CONSTITUTION: A water-soluble conjugated polymer is represented by chemical formula 1. In chemical formula 1, R is a linear or branched C1-C6 alkyl group substituted by a sulfonic acid or sulfonic acid salt, m and n is a molar fraction, where m is a real number from 0.01-0.8, and n is 1-m. The alkyl group of R is independently methyl, ethyl, i-profile, n-propyl, i-butyl, n-butyl, t-butyl, n-pentyl, i-pentyl or n-hexyl. The number average molecular weight of the aqueous conjugated polymeric compound is 3,000-100,000. The thin film sensor comprises the aqueous conjugated polymer compound.;COPYRIGHT KIPO 2013
