An overview on sensing materials depending on the electromagnetic spectra region applied

The electromagnetic spectrum covers a wide long range of light that surrounds us every day. However, our eyes are sensitive to a minor part of the light. From all regions of the electromagnetic spectrum such as microwaves, infrared light, visible light, ultraviolet light, x-rays and gamma-rays, the ultraviolet and visible ones are the most appealing to us, since here are located the optical chemosensors (fluorimetric and colorimetric) which can be sensitive and selective to several relevant analytes. Herein, we will focus in distinguishing optical probes containing invisible and visible excitable chromophores and in their chemoresponsive towards several targets in solution and also in the solid state. Probes containing chromophores as coumarin, anthracene, benzoxazole, pyrene, crown ethers (benzo)imidazole-based, anthraquinones, indolylmethanes, fluorescein, cresyl violet, rhodamine, corrole, porphyrin, as well as, boron, palladium and platinum complexes are addressed. Concerning this area, the latest advances in our group will be emphasized, such as the way to the construction of more robust and efficient systems (76 references).
