Abstract:
We demonstrate a facile synthetic route to functional disubstituted polyacetylenes bearing highly polar groups based on polymer reactions. A pentafluorophenyl (PFP) ester-containing diphenylacetylene was designed and polymerized to obtain PFP activated ester-functionalized disubstituted polyacetylene (P1). P1 was used as a parent polymer to further react separately with diverse amines, giving rise to a series of functional disubstituted polyacetylenes with a chiral moiety and hydroxyl and carboxyl groups in high yields under mild condition. Spectral characterization data indicated that the polymers' structures were well consistent with the expected results. The helicity and emission property of polymers were also studied.

Esters to Carboxylic Acids: Acid-Catalyzed Hydrolysis
During hydrolysis, the ester is first activated towards nucleophilic attack through the protonation of the carboxyl oxygen atom by the acid catalyst. The protonation makes the ester carbonyl carbon more electrophilic. In the next step, water acts as a nucleophile and adds to the...
