A priori approach to the pragmatic design of functional colorants

摘要

Electromagnetic radiation and interaction of visible portion of electromagnetic radiation with materials (responsible for color perception) play a major role in the sustenance of life. Such functional aspects of materials (particularly colorants) are akin to mere aesthetic appeal they provide. Mediation of energy in this subtle way is responsible for creation and destruction of bonds in natural materials - the photosynthesis. Human ingenuity is striving hard to do reactions in this way. While it may take years to achieve this, the interaction of light with matter is today fairly well understood and we are in a position to design a molecular material with specific phtophysical and physicochemical properties.
