Synthesis, Spectral and Photophysical Properties of Anthracene Substituted Phthalocyanines; A Study as Polyurethane Electrospun Nanofibers.

We have designed and synthesized novel symmetrical anthracene substituted zinc(II), copper(II), cobalt(II) and nickel(II) phthalocyanines (PC1, PC2, PC3 and PC4) in this work. For this synthesis, we started from base-catalysed aromatic displacement reaction of 4-nitrophthalonitrile with 9-hydroxyanthracene. The resulting four phthalocyanines (PCs) have been fully characterized by a series of spectroscopic methods including electronic absorption, elemental analysis, MALDI-TOF mass, and IR spectroscopy. The aggregation behavior of these PCs was investigated in different concentrations of chloroform solution. Further thermal stability also investigated by TG analysis. Finally we successfully made phthalocyanine (PC1) blended polyurethane electrospun (ES) nanofibers.
