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 (E_g) 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.
