Sms. Chauhan et al., SYNTHESIS OF 5,10-BIS(N-ALKYLPYRIDINIUMYL-4-YL)-15,20-DIPHENYL PORPHYRINS AND SPECTROSCOPIC STUDIES IN BINARY SOLVENTS AND DDAB VESICLES, Indian Journal of Heterocyclic Chemistry, 6(1), 1996, pp. 15-20
The amphiphilic porphyrins 5, 10-bis (N-alkylpyridinium-4-yl)-15,20-di
phenylporphyrins aggregate in binary solvent systems. The incorporatio
n of amphiphilic porphyrins is monomeric at lower porphyrin to surfact
ant molar ratio and aggregate at higher molar ratio. The diameters of
empty and porphyrin incorporated vesicles are measured by Transmission
Electron Micrography and Quasi Laser Light Scattering method. Locatio
n of porphyrins into DDAB vasicles were estimated by UV-visible and fl
uorescence spectroscopy.
