1,3-Diallylbenzimidazolin-2-one (2) reacts with silver tetrafluoroborate and hexafluorophosphate salts to furnish discrete binuclear complexes, whereas reaction with silver perchlorate and triflate salts provided 1D coordination polymers. Within each of the structures the ligand adopted a different coordination mode. (C) 2014 Elsevier Ltd. All rights reserved.

Polymers and copolymers containing 1H-benzo[d]imidazol-2(3H)-one units have been synthesized under conditions generally used for the synthesis of poly(aryl ether)s. 1H-
benzo[d]imidazol-2(3H)-one behaves like a biphenol in the polymerization reaction.
The soluble homopolymer has a very high glass transition temperature (348° C.), good thermal stability, and forms flexible transparent films. Because of the low molecular weight (134.14) of the benzoimidazolone monomer in the copolymer formed with 4,4′-biphenol that contains 30 mole % of the benzimidazolone unit, only 8.9 weight % is required to raise the Tg of the poly(arlyl ether)sulfone from 220° C. to 269° C.
