Abstract:
Porphyrin monomers, 5,15-bis(4-(2,5,8,11-tetraoxatridecan-13-yloxy)phenyl)-10,20-bis(3-iodophenyl)porphyrin zinc (5a) and 5,10-bis(4-(2,5,8,11-tetraoxatridecan-13-yloxy)phenyl)-15,20-bis(3-iodophenyl)porphyrin zinc (5b), and their oligomers 6a and 6b were synthesized and characterized. The titration experiment of the monomers was carried out in THF by changing the solution percent of water. The optical properties (UV-vis and fluorescence spectra) of the monomers that possess slightly red-shifted optical spectra in water compared to the spectra obtained in THF are reported. The newly prepared porphyrin constructs were also mixed with SWCNTs to generate noncovalent hybrid materials.
