The synthesis,characterization and property hexadecyloxyacetic azobenzene-quinoline compound

以间苯二甲酸为原料,经多步反应合成了1种新型烷氧基偶氮苯-喹啉化合物(E)5-[8-(十六烷氧基)喹啉-5-偶氮]-1,3-苯二甲酸二乙酯,通过IR、UV-Vis和1 H NMR对其结构进行了表征.利用吸收光谱和发射光谱研究了目标化合物的反-顺异构化和发光性能.目标化合物(2.0×10-5 mol/L的DMF溶液)在365nm紫外光照射下,398nm处的偶氮苯-喹啉结构K带π-π*跃迁吸收峰及267nm处芳香环的B带π-π*跃迁吸收峰逐渐减弱,光照7min后达到光稳态.目标化合物(2.0×10-5 mol/L的DMF溶液)以312nm光激发下,在418nm处发射蓝紫色荧光.

A novel hexadecyloxyacetic azobenzene-quinoline compound 5-[8-（hexadecyloxyacetic） Quinolinylazo]-1,3-diethyl phthalate was synthesized through multi-step reaction with isophthalic acid as raw material. The structures and properties of the target compound were comfirmed by IR. UV-Vis and 1 HNMR. The absorption and emission spectra has rearched trans-cis isomerization of the target compound and the optical performance. The target compound （2.0×10^-5 mol/L DMF solu- tion） took place trans-cis photoisomerization under 365 nm UV irradiation,the transition absorption peak of azobenzene-quinoline at 398 nm and the transition absorption peak of aromatic rings at 267 nm were increasingly weakened. The photostationary state was obtained after irradiation for 7 min. With the ultraviolet excitement at 312 nm,target compound （2.0 ×10^-5 mol/L DMF solution） emit blue- violet fluorescence at 418 nm.
