Research Abstract

Polyether grafted-π-conjugated polymers were synthesized by polycondensation and anionic polymerization. The obtained polymers were soluble in water, lots of organic solvents and ionic liquids. Optical properties of the polymer solution depended on the donor ability of the solvents. π-Conjugated polymers introducing thermosensitive polyether were found that fluorescence behavior changed at phase transition temperature. This investigation is possible to guide a design for the functional polymer materials.
