GENERAL INTRODUCTION TO THE CHEMISTRY OF DYES 1 Principles
Cellulosic substrates include cotton rayon cellophane linen and paper all of which are very hydrophilic and therefore require hydrophilic (water soluble) dyes for their coloration from a dyebath In addition dyes must be designed that maintain affinity when the substrate is exposed to water
What is chromophore?
Definition of chromophore : a chemical group (such as an azo group) that absorbs light at a specific frequency and so imparts color to a molecule also : a colored chemical compound : a chemical group (as an azo group) that absorbs light at a specific frequency and so imparts color to a molecule also : a colored chemical compound
What is a chromophore in UV analysis?
A chromophore is a region in a molecule where the energy difference between 2 different molecular orbitals falls within the range of the visible spectrum. The present review is an attempt to provide detail knowledge and informations about cuurent status of chromophore utilization in the field of UV analysis. Content may be subject to copyright. ...
What happens when light hits a chromophore?
Visible light that hits the chromophore can thus be absorbed by exciting an electron from its ground state into an excited state. In biological molecules that serve to capture or detect light energy, the chromophore is the moiety that causes a conformational change in the molecule when hit by light.
What are examples of conjugated chromophores?
In the conjugated chromophores, the electrons jump between energy levels that are extended pi orbitals, created by electron clouds like those in aromatic systems. Common examples include retinal (used in the eye to detect light), various food colorings, fabric dyes ( azo compounds ), pH indicators, lycopene, ?-carotene, and anthocyanins.
