POLYACETYLENE SUPRAMOLECULES HAVING SELECTIVITY FOR LEAD ION, PREPARATION METHOD THEREOF AND DETECTION METHOD OF LEAD ION USING THE SAME

摘要

PURPOSE: A polyacetylene supermolecule is provided to have colorimetric and fluorescent reaction selective to a lead ion under 100% aqueous solution, and to detect lead ion with the naked eye. CONSTITUTION: A polyacetylene supermolecule is in chemical formula 1. A manufacturing method of the polyacetylene supermolecule comprises a step of mixing and polymerizing a compound in chemical formula 1 and a compound in chemical formula 3. In chemical formula 1 and 3, R1 is C1-30 alkyl group, R2 is C1-30 alkylene group, R3 and R4 is respectively C1-4 alkylene group, R5 is -COOH, and X is -NHC(CH2)CH2-. A mixing weight ratio of compounds in chemical formula 1 and 3 is 1:7-1:10.
