Abstract
At room temperature in aqueous solution, the visible absorption peak of the title isoalloxazine (III) gives a three-banded fine structure, which has been believed to appear only in enzymatic hydrophobic region, in nonpolar solvents, or at extremely low temperature. On the other hand, another amphiphilic flavin 3-hexadecyl-10-butylisoalloxazine (II) has not such a fine structure. Thus, the unusual fine structure in (III) was attributed to aggregative “stacking” of the isoalloxazine heads, and the difference in the stacking mode between (II) and (III) was discussed.
