Colored functional materials

摘要

Functional colorants are drawn from a host of dyes developed for traditional applications as most of them have the desired functionalities in one form or the other. In addition, many attempts to design the molecular structure of functional dyes using molecular orbital calculations have been successfully achieved in order to improve the characteristics of dyes or to create new functionalities. However, in the case of functional dyes used in the solid state, like organic-photoconductors, electroluminescent devices, solid-state organic solar cells, the molecular design is still to be understood more, since the electronic states in the solid state are strongly influenced by unpredictable intermolecular interactions. In short the science and technology of functional dyes encompasses the chemistry and physics of colorants together with prototype fabrication and study of photophysical properties as a function of molecular structures.
