4-Benzoylaminobenzonitrile derivatives having an electron-withdrawing group with hydrogen bonding ability such as a formyl or a nitro group at the C-3 position of the benzonitrile moiety were synthesized. They had the higher transition temperatures than the parent compound. It is explained by the intramolecular hydrogen bonding between the lateral group at C-3 and the amide proton to prohibit the free
合成了在苯甲腈部分的C-3位具有甲酰基或硝基等具有氢键合能力的吸电子基团的4-苯甲酰氨基苯甲腈衍生物。它们具有比母体化合物更高的转变温度。其解释是通过 C-3 侧基和酰胺质子之间的分子内氢键阻止围绕 N-苄腈键的自由旋转,从而使分子变平以提高转变温度。
