	abstract = {Unsubstituted beta,beta{\textquoteright}-linked diformyldipyrromethanes are promising precursors for the synthesis of novel poly dipyrromethene ligands and N-confused porphyrins. A strategy has been developed to selectively synthesize unsubstituted beta,beta{\textquoteright}-linked diformyldipyrromethanes in moderate yields starting from 2-formylpyrrole.},

	abstract = {N-Confused tetraarylporphyrins react with CH3I in the presence of Na2CO3 to give, in high yield, N,N{\textquoteright}-dimethylated N-confused porphyrin salts, which are mixtures of structural isomers. The structures of the major isomers were determined by X-ray diffraction and NMR spectroscopic analyses. These N,N{\textquoteright}-dimethylated N-confused tetraarylporphyrin salts generate singlet oxygen when irradiated at long wavelengths in the visible region, and therefore, are potential sensitizers for photodynamic therapy.
