Synthesis and Characterization of p-Phenylene di-4-(allyloxy) Benzoate

LIU Xiao-dan,GAO Jun-gang,LUO Qing-jun,ZHANG Xiao-na,WANG Yu-yang(College of Chemistry and Environmental Science,Hebei University,Baoding 071002,China)  
A novel liquid crystal compound of p-phenylene di-4-(allyloxy) benzoate(p-PDAB) from ethyl 4-hydroxybenzoate,allyl bromide and hydroquinone was synthesized.Its structure and liquid crystalline behavior were characterized by DSC,1H-NMR,FTIR,Polarizing microscope(POM) with a hot stage and XRD.The results of XRD and POM are shown that this compound is smectic liquid crystal texture. The temperature range of liquid crystalline is 160~245 ℃.
