Abstract

Abstract: Several water-and non-water-soluble symmetrical and unsymmetrical quadruply aza bridged closely interspaced cofacial bis (5, 10, 15, 20-tetraphenylporphyrin) s have been synthesized and fully characterized by 2D'H-'H NMR (COSY), 2D" C-IH NMR, FABMS, UV/vis, IR, and fluorescence spectral techniques. It was established, on the basis of'H NMR,
