摘要

In this work

DMSO was successfully converted to nitrogen-containing heterocyclic polymers as a monomer via multicomponent polymerizations with dialdehydes and diamines. A series of poly(phenylquinoline)s with high

values were obtained in satisfactory yields

performing good thermal and morphological stability. Furthermore

The thin films of poly(phenylquinoline)s exhibit high refractive index.

Abstract

Dimethyl sulfoxide (DMSO) possessing strong solvency and high boiling point is a very important aprotic polar solvent in organic and polymer synthesis. Notably

it is also a useful synthon in organic chemistry. However

the direct incorporation of DMSO in polymer synthesis remains challenging. In this work

DMSO was successfully converted to nitrogen-containing heterocyclic polymers as a monomer

via

multicomponent polymerizations (MCPs) with dialdehydes and diamines in the presence of K

-BuOK at 120 °C in 6 h. A series of poly(phenylquinoline)s with high

values (up to 5.11×10

) were obtained in satisfactory yields (up to 82%)

performing good solubility

good thermal and morphological stability as well as excellent film-forming ability. The thin films of poly(phenylquinoline)s exhibit high refractive index value in a wide wavelength range of 400–1700 nm. Thus

this work not only enriches the family of MCPs but also provides an efficient strategy for the conversion of DMSO into functional polymeric materials that are potentially applicable in diverse areas.
