Co-Catalyzed Double [4+2] Cycloaddition Reaction of Tetrakis(methylene)benzobicyclo[2.2.2]octane toward Diaryltriptycenes

Abstract

Abstract Tetrakis(methylene)benzobicyclo[2.2.2]octane (TMBO) was used as a novel synthon for triptycene derivatives. Co-catalyzed double [4+2] cycloaddition of arylacetylene and TMBO resulted in diaryl-substituted meso and chiral triptycenes. The obtained chiral molecules exhibited circularly polarized luminescence (CPL), which was elucidated using theoretical calculations.
