Periodic Donor-Acceptor (Co)polyarylenephthalides with Tunable Photoluminescent Parameters

The macromonomers of the dyad (O Y O) and triad (O Y O Y O, O Y T Y O) structure (with О being diphenylene oxide, T being terphenylene, and Y being the phthalide cycle) as well as a series of (co)poly-arylenephthalides with general formula [(O Y)p (T Y)q ] n differing in the ratio between the diphenyleneoxyphthalide p and terphenylenephthalide q groups ( p : q = 0 : 1, 1 : 1, 2 : 1, 3 : 1, 1 : 0) have been synthesized. Photooptical and emission properties of the solutions and thin films of the synthesized (co)polymers and their aggregates formed upon the addition of a bad solvent have been investigated.
