through the cycloaddition reaction between Fischer carbene and oxazolones. The absorption spectra of all compounds present a main peak due to the HOMO-LUMO electronic transition, as supported by the theoretical study. The maximum has large absorption coefficient ε (∼104 M−1cm−1) and is in the green region from 514 to 531 nm, red shifted with respect to unsubstituted BOPHY. The dihedral angle between the
