摘要

为了寻找新的热致性和光开关材料，制备了一些4′-烷氧基-4- (ω -肉桂酰烷氧基)偶氮苯。合成过程包括4-硝基苯酚的O -烷基化，然后是硝基的还原(h2, Pd/C)，苯胺的重氮化，随后与ω -羟基烷氧苯反应，然后是改性的appel型酯化(brccl3, pph3)。研究了这些物质的光化学行为。

Synthesis of 4′-Alkoxy-4-(ω-cinnamoylalkoxy)azobenzenes and Their Photoswitchable Behavior

: In search of new thermotropic, photoswitchable materials, a number of 4′ -alkoxy-4- (ω -cinnamoylalkoxy)azobenzenes were prepared. The synthetic procedure included O -alkylation of 4-nitrophenol, followed by reduction of the nitro group (H 2 , Pd/C), diazotization of the aniline and subsequent reaction with ω -hydroxyalkoxybenzenes, followed by a modified Appel-type esterification (BrCCl 3 , PPh 3 ). The photochemical behavior of the substances was investigated.
