exhibits a fluorescence at λ>400 nm, which strongly shifts to the red with increasing polarity of the solvent. The corresponding solvatochromic plot is indicative of an emissive, lowest energy charge-transfer (CT) state. Stern-Volmerquenching of the fluorescence by dilute methanol in pentane gives a linear plot with a unit intercept and a slope k Q τ ct =0.70. Quenching is accompanied by formation of
