含PAH弯曲核的香蕉型分子的合成及其结构(英文)

Synthesis and Characterization of New Banana Shape Molecules with PAH as Bend Central Cores

设计合成了2个分别以DBN(二苯并并四苯)及三苯基吡啶为中心弯曲核的2个香蕉型分子,通过1H-NMR,13C HRMS等手段对其结构进行了表征,在偏光显微镜下,没有观察到它们的液晶行为.

Two new banana shape compounds with DBN （ Dibenzo[ fg, op] naphthacene） and triphenyl pyridine as bend central cores respectively were synthesized, their structures were confirmed by 1 H- NMR and 13C- NMR and their mesophase behaviors were investigated by POM. No mesomorphic behavior is found in such two compounds.
