Novel diarylethene derivatives: N-substituted-3,4-bisheteroaryl-2,5-dihydropyrroleswere synthesized through Mcmurry couple reaction with high yields. The photochromic propertiesand UV-Vis absorption spectra were studied. The maximal absorptions of their close forms werearound at 406 nm or 446 nm, which related mainly with heteroaryl groups but not with substitutedgroups at nitrogen atom of dihydropyrrole. The absorption of their colored form could be matchedwith blue light laser.
