However, the CPL g values of the resulting molecules in solution, which is preferable than the solid-state study due to the suppressed overestimation , remain low (typically 1×10 -3 -3×10 -3 ). Thus, the development of a rational molecular design strategy to obtain both TADF-activity and high g values is needed. Carbazole-substituted donor-acceptortype (D-A-type) benzophenone derivatives have been reported to exhibit TADF-activity , which naturally led us to envision a carbazole-substituted D-A-type CBBC derivative.
