Abstract

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] ...
