The thermal properties of some cholesteryl and b-sitosteryl benzoates incorporating polar terminal groups: The thermal properties of some cholesteryl and b-sitosteryl benzoates incorporating polar terminal groups. Takenaka, Shunsuke; Koden, Mitsuhiro; Sugiura, Hisanori; Kusabayashi, Shigekazu (Fac. Eng., Osaka Univ., Suita 565, Japan). Mol. Cryst. 23838-12-2 is the cas registry number. This chemical is also mentioned in this article. Liq. Cryst., 141(1-2), 97-106 (English) 1986. CODEN: MCLCA5. ISSN: 0026-8941. DOCUMENT TYPE: Journal CA Section: 75 (Crystallography and Liquid Crystals) Some cholesteryl and b-sitosteryl benzoates having a nitro or a cyano group at the o-, m-, and p-positions, and their related compds. were studied. When a cyano or a nitro group is introduced at the p-position, the mols. tend to display a smectic A phase and a highly stable cholesteric phase. The smectic A (SA) phase has a bilayer arrangement of the mols., and is isomorphous with the SA2 phase of polar liq. crystals, and has no affinity with the SA1 phase of nonpolar liq. crystals, or the SAd phase. The SA2 phase was also formed by the o- and m-nitro substituted derivs. The polar interaction around the benzoate moiety is proposed to be responsible for the formation of the antiparallel dimers. .

I (Chol = 5-cholest-3b-yl; R, R1 = H, F, Cl, Br, NO2, OMe, Me) were shown to exist, in the majority of cases, as mixts. of syn and anti conformers on the basis of IR spectra (in the region of the carbonyl group absorption) and theor. conformational anal. of model cyclohexyl benzoates. The anti conformers I are energetically favored. The entropic factor dets. the position of the conformational equil. for cholesteryl o-chloro- and o-bromobenzoates. .
