ABSTRACT

In the approaching century, the energy demand is going to be a major problem. To combat this, scientists are trying to invent novel and reliable alternative energy sources, storage and conversion options instead of using conventional sources of energy (such as, gasoline, petrol, diesel etc.). Chemistry, being a stream of central science, is trying to contribute in this regard. Chemistry is capable of forming various molecules having myriads of bonding connectivity, charge separations, geometry, size, shape, surface charge etc. These molecules can be of a wide range starting from a simple small molecule to novel high-molecular weight conducting polymers, or a complex material like porous polymer, covalent organic framework, and metal-organic framework. These molecules due to their π electron cloud, charge separation, and three-dimensional geometry have proven to transport electrons through a porous network and come up as reliable candidates for electrochemical energy storage and conversion. In the chapter, the recent developments in the field of energy storage and conversion are summarized. The interest lies mainly in the synthesis of conducting polymers, covalent organic framework and their applications as various energy sources.
