Significance

The authors present new B,O-chelated azadipyrromethenes combining two ­BODIPY-derived scaffolds with red-shifted fluorescence. They first attempted simultaneous deprotection and cyclization of 1a-d; however, the desired product containing electron-donating groups (EDG) was not isolated. A second route was then developed following a known mechanism starting from chalcones 3a-c.
