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