Functional polyacetylenes containing pyridinium side groups(PPyA-MX,X = Br and I) were successfully synthesized.Spectroscopic techniques such as ^1H-NMR,^(13)C-NMR,and FTIR spectroscopy were used to characterize the structure of the obtained polymers.The characterization data were well consistent with the expected macromolecular structures.PPyA-MI had good solubility in polar organic solvents and low solubility in water,while PPyA-MBr had good solubility in both polar organic solvents and water.
A new bis(aroylacetylene) containing tfiazole and fluorene moieties is synthesized by click chemistry. Polycyclotrimerization of the monomer is catalyzed by piperidine in refluxed dioxane,furnishing a regioregular poly(aroylarylene) in a satisfactory yield.The hyperbranched structure of the polymer is characterized spectroscopically with satisfactory results.The polymer enjoys no metal detriment and is soluble in common organic solvents such as tetrahydrofuran (THF),chloroform,dichloromethane (DCM),and N,N-...
