Photophysical characterization of hydroxy and ethoxy phenalenone derivatives

[Display omitted] •Presence of hydroxy and alkoxy derivatives modulates photophysics of phenalenone.•Singlet oxygen quantum yield is lowered with respect to unsubstituted phenalenone.•New non-radiative decay paths for singlet excited state are opened. Phenalenone has been extensively studied due to...
