Synthesis and characterization of a novel hexabenzocoronene (HBC) derivative attached with four alkyl swallow-tailed chains and two sulfur-containing chains are described. The designed peripheral decoration with dove tails as solubilizer and sulfur-containing groups as functionalizer is expected to improve the solubility of molecules, change the columnar spacing stacks and make for its orientation on matrix surface. Its UV−vis absorption spectra appeared in 350-400 nm region as same as typical that of this kind of compounds. The thermal properties as discotic liquid crystal and its orientation on matrix are being studied.

AbstractIR-LD spectroscopic analysis using nematic liquid crystal suspension as a solid-state orientation technique and the reducing-difference procedure for polarized spectra interpretation are applied to the α-and β-polymorphs of glycine. Both structural analysis and detailed IR band assignments were carried out.
