Azo dye, and preparation method and application thereof
The invention discloses an azo dye represented by formula I shown in the specification, and a preparation method and application thereof. The azo dye provided by the invention has remarkably high dichroism, the solubility of the azo dye in a liquid crystal medium can reach 2 wt% or above, and when the azo dye is applied to a guest-host liquid crystal composition, a liquid crystal display device containing the guest-host liquid crystal composition can have higher contrast.

Alkoxylated p-phenylenevinylene oligomers: Synthesis and spectroscopic and electrochemical properties
Twenty-one n-alkoxy substituted phenylenevinylene oligomers were synthesized, varying in size, number and position of the OR groups. IR,MS and solubility data are presented. NMR measurements provided the molecular structure as well as information about conformations and molecular dynamics. UV and of cyclic voltammetric data give correlations of chemical structure (number and position of OR substituents) with separate HOMO and LUMO energies.

Synthesis and antirhinovirus activity of 6-(dimethylamino)-2-(trifluoromethyl)-9-(substituted benzyl)-9H-purines
A series of 6-(dimethylamino)-2-(trifluoromethyl)-9-(substituted benzyl)purines was synthesized and tested for antirhinovirus activity. Most of the compounds were synthesized by alkylation of 6-chloro-2-(trifluoromethyl)-9H-purine with the appropriate benzyl halide followed by displacement of the chloro group with dimethylamine. Alternatively, 6-(dimethylamino)-2-(trifluoromethyl)purine was alkylated with the appropriate benzyl halide. Although several different aryl substituents provided compounds with IC50's = 0.03 μM against rhinovirus serotype 1B, no congener was significantly more active than the parent 2. Twenty-three compounds were tested against 18 other serotypes, but none exhibited a uniform profile of activity.
