Phthalimido-boronsubphthalocyanines: New Derivatives of Boronsubphthalocyanine with Bipolar Electrochemistry and Functionality in OLEDs.

Phthalimides have been found to react with Cl-BsubPc to produce a new class of BsubPc derivatives, phthalimido-boronsubphthalocyanines (Phth-BsubPcs). They exhibit a high quantum yield for photoluminescence (Φ), maintain a high molar extinction coefficient (ε) and have bipolar electrochemical stability previously unseen in simple BsubPc derivatives. Their bipolar electrochemical characteristics have been extended into simple organic electronic devices: in OLEDs as charge transporters and emitters.
