英文摘要	beta-Amino triphenylenes can be accessed via palladium catalyzed amination of the corresponding, triflate using benzophenone imine. Transformation of amine 6 to benzoyl amide 18 is also straightforward, and its wide, mesophase range demonstrates that ,the new linkage supports Columnar liquid Crystal formation. Amine 6 also undergoes clean aerobic oxidation to give a new twinned structure linked through an electron-poor pyrazine, ring. The new discotic liquid crystal motif contains donor and acceptor fragments and is more oval in shape rather than disk-like. It forms a wide range columnar mesophase. Absorption spectra are strong and broad; emission is also broad and occurs with a Stokes shift of ca. 0.7 eV, indicative of charge-transfer character.; NSFC [21174016, 11474017]; RFDP [20120009110031]; SCI(E); PubMed; ARTICLE; zhqhe@bjtu.edu.cn; a.cammidge@uea.ac.uk; 13; 3286-3289; 17
