文摘

A gallamide-containing pseudoenantiomeric helicene pair bearing a (10R,11R)-dimethoxymethyldibenzosuberane core can self-assemble by intermolecular amide H-bonding and 蟺-蟺 stacking into bundled helical fibers with helical tunnels of complementary helicity in CH₂Cl₂. The helicenes undergo excellent complementary photoswitchings of ternary logic at 280, 318, and 343 nm through (鈭?-gel-sol-(+)-gel interconversion.
