以4,4′-二羟基二苯甲酮为中心结构基元, 以酯基(—COO—)作为桥键, 烷基(m=5,6,7,8,9,10)为末端基团, 合成了一系列新型香蕉形液晶化合物(mPEPK), 通过IR、1H NMR、13C NMR和MS鉴定这些化合物的结构正确, 并经过差热扫描仪(DSC)和偏光显微镜(POM)测定其相变温度和相态织构。结果表明, 所合成目标化合物具有近晶相, 并且相转变温度较类似结构香蕉型液晶化合物有大幅度降低。 A novel series of bent-core molecules (mPEPK) was prepared with a central bent core based on 4,4-dihydroxybenzophenone (DHBP), ester group bridge(—COO—), and alkyl tails with different carbon numbers (m...

A novel series of bent-core molecules （mPEPK） was prepared with a central bent core based on 4,4-dihydroxybenzophenone （DHBP）, ester group bridge（—COO—）, and alkyl tails with different carbon numbers （m= 5, 6, 7, 8, 9, 10.）. The structures of the titled compounds were confirmed by IR, 1H NMR, 13C NMR, MS spectra, and their transition temperatures and phase textures were investigated by using differential scanning calorimetric（DSC） and polarizing optical microscopy（POM）. A part of the compounds exist smectic phase. Comparing with t...
