摘　　要：Three new diarylethenes 1--3 combined with quinoline derivatives have been synthesized. Through controlled chemical condition of deprotonation/protonation, they presented some new irreversible photochromic phenomenons under UV/Vis light irradiation in chloroform solution. It was found that 1--3 had well photoisomerization upon UV/Vis light irradiation in neutral chloroform solution. Addition of acid to the solution of the ring-opening isomers of 1--3 produced 1 oa--3oa, which performed reversible photochromic behavior under UV/Vis light irradiation and reversed back to 1--3 under neutralizing with adding lewis base. However, addtion of base to neutral soluton of the ring-opening isomers of 1--3 produced lob--3ob, which could not change to the deprotonated ring-closing isomers under UV light irradiation.Three new diarylethenes 1--3 combined with quinoline derivatives have been synthesized.
