摘要:

A copper(Ⅱ) phthalocyanine containing four benzo-15-crown-5 moieties was successfully synthesized from 4',5'-dibromobenzo-15-crown-5. The electronic absorption spectra of the phthalo-cyanine in chloroform-methanol with different amounts of KCl were measured. One can find that when the[K+]/[phthalocyanine] ratio is increased from 0 to 2, the peak at 678nm is decreased and finally disappears, and at the same time the peak at 630 nm appears and is increased.
