摘要:
A new surface-active porphyrin, 1-dodecyl-4-(10,15,20-triphenyl-5-porphinyl)pyridinium bromide, and its copper complex (Cu(II)DPyTPP) were synthesized. In toluene, chloroform and ethanol, a typical ESR hyperfine structure (hfs) ascribable to monomeric Cu(II) porphyrin was observed. In ethanol containing a buffer of pH=7.4, a reversible formation of the micellar colloid which is strongly dependent on the water/ethanol mixing ratio, was confirmed based on mearsurements of ESR line broadening and the splitting of the Soret band.
