Tetra( N ‐R‐pyridinium‐4‐yl)porphyrin and tetra( N ‐R‐pyridinium‐3‐yl)porphyrin derivatives were synthesized with R = 3, 6, and 8 carbon alkene, alcohol and carboxylic acid chains. Self‐aggregation of these systems was studied at I = 0.1 using visible spectroscopy. N ‐Alkyl chain length and functionality were determined to play the dominant role in aggregation of the cationic porphyrins. Position of peripheral charge ( meta vs. para ) also influenced spectral changes and the nature of the aggregate.
