Synthesis of Meso substituted uracil porphyrin and the analysis of their assembling structures induced by melamine derivatives

Porphyrin derivatives UP1 were synthesized whose uracil groups were connected via amide bonding and their structures were analyzed by ¹H-NMR. Moreover, the structure of self-assembly that was formed by UP1 and melamine derivatives M was analyzed by ¹H-NMR and SEM. It was investigated that UP1+M were aggregated because of the mixture of atrop isomers. UP2 whose uracil groups were directly connected to its Meso position was also analyzed by ¹H-NMR and their structure or the existence of atrop isomers was argued.
