Abstract
The quternization polymerization of pyridylacetylenes using appropriate reactants is a versatile platform for the synthesis of ionically functionalized polyacetylenes. A polyelectrolytic polyacetylene derivative with pyrene substituents was synthesized via In-situ quternization polymerization of 2-ethynylpyridine using 1-(bromoacetyl)pyrene. The monomeric N-(2-oxo-2-((pyrene)ethyl)-2-ethynylpyridinium bromide firstly formed from the reaction of 2-ethynylpyridine and 1-(bromoacetyl)pyrene was spontaneously polymerized without any additional catalyst systems to give the ionic polyacetylene in high yield (85%). The analysis results on the polymer structure using instrumental methods such as IR, NMR, and UV-visible spectroscopies showed that the polymer has the conjugated backbone system with the designed pyrene moieties. This polymer dissolves well in organic solvents such as DMSO, DMF, DMAc, etc.
