摘要

A series of poly(

-terphenyl acetylene)s was prepared

in which large

-terphenyl units were directly linked to the polyene backbone

thereby significantly enhancing the steric repulsion between side groups to afford stretched poly(phenylacetylene)s with large conjugated lengths and near-infrared optical activity.

Abstract

Poly(phenylacetylene)s (PPAs) are one kind of important helical polymers with tunable main chain conformations. However

the preparation of near-infrare

d optically active helical PPAs remains a challenge. Here

we report a novel helical poly(

-terphenyl acetylene)s (PTPAs) bearing two chiral alkylamide pendants

which showed a stretched

cis-transoid

helix in solution or poly(methyl methacrylate) matrix with a broad optical activity range from the ultraviolet-visible (UV-Vis) to near-infrared regions. The effects of substituents

solvents

temperature

and acid/base additions on the helical conformation were carefully investigated. The substituent structure had little effect on the elongation but remarkably affected the main chain screw sense. The stability of this extended

cis-transoid

helix depends on the solvent applied and the temperature. Reversible conformational transitions between the one-handed

cis-transoid

helices and frustrated coil conformations can be achieved by the addition of trifluoroacetic acid and triethylamine. Furthermore

full-color circularly polarized luminescent materials can be prepared by virtue of their broad Cotton effects and chirality-selective absorption.
