N, N'-dimethylated N-confused porphyrins

摘要

A series of N,N'-dimethylated N-confused porphyrin salts were synthesized through methylation of N-confused porphyrins using MeI in the presence of Na2CO3. These compounds have an intense absorption around 790 nm. It has also been shown that N,N'-dimethylated N-confused porphyrin salts can generate singlet oxygen when irradiated. They are, thus, potential sensitizers for PDT.
