Determination of Melting Point of Oligomer Metal Complexes Derived from Bisamic Acid of Pyromellitic Dianhydride and 4-Bromoaniline by Capillary Method (CAT#: STEM-PPA-0114-YJL)

Introduction

The design and construction of polymeric metal complexes have received great attention. The structures of metal complexes are depending upon the structure of the organic ligands, the coordinative geometry of metal ions, metalligand ratio, and other factors. Among various organic ligands, multicarboxylate ligands are often used to synthesize polymer metal complexes; for example, 1,2,4,5-benzene-tetra carboxylate, 3,3’ , 4,4’-biphenyl tetra carboxylic acid,1,1’-biphenyl-2,3’,3,4’-tetra carboxylic acid, and methylene diisophthalic acid have been extensively used for the synthesis of various polymer metal complexes. On the other hand, the use of auxiliary N-containing ligands is also an effective method for the framework formation of polymer metal complexes owing to the fact that they can satisfy and even mediate the coordination needs of the metal center and consequently generate more meaningful architectures. The oligomer metal complex based on bisamic acid of pyromellitic dianhydride has not attracted any attention.
