Two novel alkoxy azobenzene-quinoline compounds (E)-diethyl 5-[(8-butoxyquinolin-5-yl) diazeny]isophthalate (5a)and (E)-diethyl5-[(8-octoxyquinolin-5-yl)diazeny]isophthalate (5b)was synthesized through multi-step reaction with isophthalic acid as raw material .The structure and prop-erties of the target compound were comfirmed by IR ,UV-Vis ,1 H NMR and MS .Through the absorp-tion and emission spectra trans-cis isomerization of the target compound and the optical performance has been studiet .The target compounds 5a and 5b(2 .0 × 10-5 mol/L DMF solution) took place trans-cis photoisomerization under 365 nm UV irradiation ,the transition absorption peak of azobenzene-quinoline at 400 nm and the transition absorption peak of aromatic rings at 267 nm were increasingly weakened .The photostationary state was obtained after irradiation for 6min .With the ultraviolet ex-citement at 311 nm ,target compounds 5a and 5b (2 .0 × 10-5 mol/L DM F solution ) emit blue-violet fluorescence at 420 nm and 418 nm .
