Abstract:A series of Schiff bases containing the indole group were synthesized. The compound 2-[(1-methyl-1H-indol-3-yl)methylene] hydrazinecarbothioamide (4) exhibits excellent reversible photochromic properties both in solid - solid state and solution. Moreover, the nanofiber containing the compound 4 also shows excellent photo chromic properties, which are better than the amorphous powder of 4 itself. Based on the experiment results and theoretical calculation, we confirm that the photochromic properties originate from the intermolecular proton transfer, resulting in the isomerization of the thioketone - form and the thioalcohol - form in the hydrazinecarbothioamide. This unique photochromic system is obviously different from that of traditional Schiff bases, such as salicylideneanilines.
