Organic chromophores are molecules that absorb and emit light, typically in the visible or ultraviolet regions of the electromagnetic spectrum. These molecules play a crucial role in various fields such as materials science, biology, and photonics. Organic chromophores can be classified into different categories based on their structure and properties, including dyes, fluorescent probes, and conjugated polymers. Researchers study organic chromophores to understand their optical properties, to develop new materials for applications in solar cells, light-emitting diodes, sensors, and biological imaging, and to explore their potential for use in advanced technologies.
