The development of polymers is one of the biggest achievements made in chemistry which has a significant effect on every day life. Remarkable improvement in humanity's progress has been observed from the "Stone era" to the "Iron era" to the "Bronze era" to the "Polymer era." "Polymer" is now a household word. Polymeric metal complexes known as coordination polymers are defined as polymeric substances which are composed of metal ions or clusters connected by poly topic organic linkers via strong coordination bonds. In recent years, the design and construction of coordination polymers have attracted increasing attention. Hence, we have carried out the synthesis and characterization of various coordination polymers of organic ligands derived from 8-hydroxyquinoline and 2,2'-(phenyl azanediyl) diethanol derivatives. The aim of this book is to provide a brief knowledge about coordination polymers.
