Excitation and emission scans at 295 and 77 K in 200 μM toluene solutions of a, TTM-1Cz, b, TTM-1Cz-An, and c, TTM-1Cz-PhAn. Intensity monitored at luminescence maxima during excitation scans. Vibronic progression reminiscent of pure anthracene is seen in TTM-1Cz-An and TTM-1Cz-PhAn at low temperatures.
