Figure 4. Multicolour luminescence of 1Inline graphicVOCs.

Figure 4

(a) The resulting luminescence of crystal powders of 1, suspended in each VOC liquid after excitation at 365 nm using a commercial ultraviolet lamp. (b) Height-normalized luminescent spectra of 1Inline graphicVOCs after excitation at 370 nm. (c) The relationship between the emission energy of 1Inline graphicVOCs and the ionization potential of each VOC48. The linear correlation implies that the CT complexation dominates the fluorescence.
