Abstract

5,10,15-Tris(αpha;,αpha;,αpha;-o-pivalamidophenyl)-20-[αpha;-o-[4--[[12-(l-imidazolyl) dodecyl] carbamoyl] -2, 2-dimethylbutanamido]phenyl]porphyrins were synthesized. The long alkyl-chained derivative (n = 12) [8] was chemically stable, but the short alkyl-chained derivative (n=3) [10] gradually decomposed on exposure to air and room light in dilute benzene solution. Two reasons were considered to contribute to the stability of the porphyrin [8]: The long distance between the porphyrin ring and the imidazole ring and the preservation of fully delocalization of 18-π; electron of the porphyrin system. Conformational structure of the iron(II) complex of [8] was also discussed.
