WebA chromophore is that part of the molecule where the absorption proceeds and where the main change of the geometry or electron density, etc. appears after the excitation process. The area of the chromophore is not very well demarcated from the residual parts of the molecule which are not involved in the absorption process. WebFluorogens are an attractive type of dye for imaging applications, eliminating time-consuming washout steps from staining protocols. With just a handful of reported fluorogen-protein pairs, mostly in the green region of spectra, there is a need for the expansion of their spectral range. Still, the origins of solvatochromic and fluorogenic properties of the …
