have been efficiently synthesized through the reaction of 2,4-disubstituted pyrroles with aromatic aldehydes followed by oxidation with DDQ and reaction with BF3OEt2. The investigation of the photophysical properties of the prepared compounds revealed that they have a maximum of absorption 565 ± 5 nm and a maximum of emission at 620 ± 10 nm in DCM with quantum yields from 12% up to 96%.
