Abstract:An effective hole transport material (HTM) should have
the characteristics
of high hole mobility, good film-forming property, and a well-matched
energy level. In this work, we designed and synthesized two Y-shaped
HTMs, in which the phenanthrol[9,10-d]imidazole group
was integrated as the plane π building block into triphenylamine
