Study of the Position of the Conjugated Substitute Influence on the Optical Properties of the Kaede Protein Chromophore Derivatives

摘要

We report novel derivatives of a chromophore of the fluorescent protein Kaede, (Z)-2-(4-methoxybenzylidene)-6/8-phenylimidazo[1,2-a]pyridine-3(2H)-ones. The introduction of phenyl substituent in the 6- and 8-position of the imidazopyridinone fragment does not lead to a shift in absorption and emission spectra.
