Abstract

The synthesis, thermal, and photoluminescence properties of novel platinum metallopolyynes of electron-deficient acridone derivatives with electronically tunable bandgaps and their molecular model complexes are described. Polymer P2 has an optical bandgap (Eg) of .10 eV which is much lowered than that of P1 (2.60 eV). The incorporation of electron-accepting dicyanomethylene units on the acridone ring in the main chain creates a strong π-conjugated system that features unique donor-acceptor interactions and intramolecular charge-transfer states.
