Two types of azobenzene derivatives I [R = CH2COOH, CH2COOEt, CH2(CH2)4CH2Br] based on Disperse Yellow 7 I [R = H] (4-[4-(phenylazo)phenylazo]-o-cresol) were synthesized. The first compound I [R = CH2(CH2)4CH2Br] was synthesized by alkylation of DY7 with an excess of 1,6-dibromohexane in the presence of a mild base (K2CO3). The second one I [R = CH2COOH] was obtained by the alk. hydrolysis of the ester bond of the newly obtained DY7 derivative with the ethoxycarbonyl group. The synthesized compounds were characterized by different spectral anal. techniques such as 1H NMR, 13C NMR, FT-IR, and UV-Vis. They could be employed for the synthesis of a wide variety of azo-based materials, which may be suitable for photochromic systems and mol. electronics applications. In the experiment, the researchers used many compounds, for example, 1,6-Dibromohexane(cas: 629-03-8Application of 629-03-8)
1,6-Dibromohexane(cas: 629-03-8) is generally used to introduce C6 spacer in the molecular architecture. Some of the examples are: synthesis of pyrrolo-tetrathiafulvalene molecular bridge (6PTTF6) to study redox switching behavior of single molecules; synthesis of water-soluble thermoresponsive polylactides.Application of 629-03-8
