Popis:	Single crystals of 1-alkylthymine (carbon numbers of the alkyl chain were 8, 11, 12, 13, 14, and 16) were obtained from N,N-dimethylformamide (DMF) solution as plates, and the crystal structures were determined by X-ray crystal analysis. The terminal methyl group of the alkyl chain was found to approach to the double bond of the thymine base in the crystal. The thymine bases in these crystals did not give the photodimer by UV irradiation, while the crystals obtained from ethyl acetate and acetonitrile gave the photodimer as reported previously. The terminal methyl group of the alkyl chain was concluded to inhibit the rotation of the thymine bases in crystal, which made the crystal from DMF inactive for the photodimerization.
