PB18 側鎖にトリアルキルシリル基を導入したディスコチック液晶化合物の合成と物性(化学・材料,ポスター発表,2012年日本液晶学会討論会)

抄録

Novel discotic liquid-crystalline materials were synthesized from triphenylene and hexabenzocoronene by attaching trialkylsilyl groups in the side chains. These compounds dissolved well in hexane, toluene, chloroform, diethyl ether and THF. DSC, POM and XRD measurements proved that triphenylene and hexabenzocoronene derivatives exhibit Col r and Col ho masophases respectively, over wide temperature ranges. Trialkylsilyl group was shown to be an effective flexible moiety of liquid-crystalline materials to improve solubility in organic solvents.
