Abstract

Cholesterol-based gelators 1 bearing a porphyrin moiety were synthesized. (S)-1 with a natural C-3 configuration could gelatinize a few solvents whereas (R)-1 with an inverted C-3 configuration could not gelatinize any solvent. The absorption and CD spectra for less cohesive (R)-1 were changed only to a smaller extent at 10^-5∼10^-2 mol dm^-3 whereas more cohesive (S)-1 gave a new λ_max at 444 nm and its corresponding CD band only in the gel phase. The results indicate that "gelation" is a new strategy to create ordered porphyrin assemblies.
