Preparation of Poly(ethynylpyrydine)s and Their Salts; Spectroscopic Study of Their SERS-Active Systems with Silver Hydrosol

Abstract

Various Poly(N-alkyl-x-ethynylpyridinium halogenide)s Have Been Synthesized via Direct Spontaneous, Catalyst-free Polymerization of x-Ethynylpyridines with Alkylhalogenides. Systems Polymer/Ag Hydrosol Were Characterized by SERS.
