of tuning these fluorescent molecules to higher wavelengths. This is vital since different tissues are sensitive to varying wavelength emissions. To address this need, we report the discovery, tuning, structure-photophysical property relationships (SPPR), and time-dependent DFT (TD-DFT) computations of 400–700+ nm fluorescent pyrido[2′,1′:2,3]imidazo[4,5-c]isoquinolines and substituted imidazo[1,2-a]pyridin-3-amines
method for synthesizing imidazo[1,2-a]pyrazines and imidazo[1,2-a]pyridines via one-pot three-component condensations has been reported. The product, generated in situ by the reaction between an aryl aldehyde and 2-aminopyridine or 2-aminopyrazine, undergoes [4 + 1] cycloaddition with tert-butyl isocyanide, affording the corresponding imidazopyrazine and imidazopyridine derivatives in good yields.
