Synthesis optical and nonlinear optical characterizations of novel organic materials

Abstract

To cater the need of society, the ever growing demand of variety of materials with various specific properties has been a challenge worldwide. Investigations in the field of metallurgy dealing with metallic eutectics, monotectics and inter-metallic compounds are carried out and a variety of products for commercial and technological importance have been produced. Although metallic systems are significant capable of producing materials of desired properties, their detailed investigations are difficult because of high transformation temperature, opacity, density driven convection effect, a limited choice of material and difficulty involved in their purification. On the other hand, low transformation temperature, transparency, wider choice of materials, small density driven convection effects and ease in purification are the special features of organic systems to be considered. In the last few decades, there have been continuous efforts to explore the organic systems with regard to their physicochemical and optical properties which ultimately is helping in producing newer materials of technological importance. newlineOrganic materials are known for different electronic applications such as conductors, semiconductors, light emitting diodes, dielectrics, nonlinear optical materials, frequency doubling, terahertz generation, transistors, liquid crystal display (LCD), etc. The main advantage to work with organic materials is wider choice of materials to design and produce the novel materials with desired properties. During the last two decades, the significant research efforts have been made for the designing of novel organic materials for different applications which offer large hyperpolarizability and quick response than those of inorganic materials. Furthermore, organic molecules can be engineered with great ease by slight alterations in the functional groups and also the experimentation is cost effective as compared to their inorganic counterparts.
