By incorporating electron-accepting benzimidazole and electron-donating indolo [3, 2-b] carbazole into one molecule, two novel donor–acceptor bipolar host materials, TICCBI and TICNBI, have been synthesized. The photophysical and electrochemical properties of the hybrids can be tuned through the different linkages (C-or N-connectivity) between the electronic donor and acceptor components. The promising physical properties of these ...
