Mono-, Di-, and Trimetallic Palladium(II)Porphyrin Trimers with Etheno-bridges
Mono-, di-, and trimetallic Pd(II) complexes of the etheno-bridge porphyrin trimer <B>1</B> were prepared. It was found that the metalation of <B>1</B> first occurred in the inner porphyrin ring. The trimetallic Pd(II) trimer <B>6</B> exibited splitting of the Soret band and complete disappearance of the weak bands ranging from 600 to 1000 nm unlike the corresponding free-base and Ni(II) porphyrin trimers.
