^aExcited at 380 nm (9), 400 nm (5) and 365 nm (1–4, 6–8 and 10).

^bAccording to fluorescence decay traces.

^cQuantum yields were obtained from an integrating sphere.

^dCalculated by QY = τk_r = k_r/(k_r + k_nr).

^eFilms were prepared by spin-coating a dilute DCM solution on a quartz plate.

^fExcited at 365 nm.

^gEmission is too weak to be detected.

^hNo single crystal was obtained.
