Popis:	New nonsymmetric dihetarylethenes were synthesized: 3-(5-methoxy-1,2-dimethyl-1H-indol-3-yl)-4-(3-thienyl)furan-2,5-dione and photochromic 1-alkyl-(1-aryl)-3-(5-methoxy-1,2-dimethyl-1H-indol-3-yl)-4-(3-thienyl)-1(H)-pyrrole-2,5-diones. The absence of benzoannulation in the indole moiety results in the enhancement of the efficiencies of fluorescence and photocyclization of noncyclic isomers compared to the benzoindole derivatives.
