Synthesis and binding behavior of a Zn(II)-porphyrin having calix[5]arene cap
摘要:
The synthesis and binding behavior of a Zn(II)-porphyrin having a calix[5]arene cap are presented. In order to synthesize such a bridged porphyrin, 5,15-bis(7-carboxy-1-naphthyl)-10,20-diphenylporphyrin having the syn arrangement of two naphthalene rings has been prepared. Amidation of the porphyrin and calix[5]arene having two amino functions and subsequent treatment of Zn(OAc)(2) gave a calix[5]arene capped Zn-porphyrin. Calix[5]arene-Zn-porphyrin was found to bind 4-methylpyridine much stronger than TPP-Zn. (C) 2002 Elsevier Science Ltd. All rights reserved.
