Then, FIG. 14 shows the absorption spectrum and the emission spectrum of 2mPCCzPDBq in a toluene solution of 2mPCCzPDBq, and FIG. 15 shows the absorption spectrum and the emission spectrum of 2mPCCzPDBq in a thin film of 2mPCCzPDBq. The spectra were measured with a UV-visible spectrophotometer (V550, produced by JASCO Corporation). The spectra of 2mPCCzPDBq in the toluene solution of 2mPCCzPDBq were measured with the toluene solution of 2mPCCzPDBq put in a quartz cell. The spectra of 2mPCCzPDBq in the thin film of 2mPCCzPDBq were measured with a sample fabricated by deposition of 2mPCCzPDBq on a quartz substrate by evaporation. Note that in the case of the absorption spectrum of 2mPCCzPDBq in the toluene solution of 2mPCCzPDBq, the absorption spectrum obtained by subtraction of the absorption spectra of the quartz cell and toluene from the measured spectrum is shown, and in the case of the absorption spectrum of 2mPCCzPDBq in the thin film of 2mPCCzPDBq, the absorption spectrum obtained by subtraction of the absorption spectrum of the quartz substrate from the measured spectrum is shown.
As shown in FIG. 14, in the case of 2mPCCzPDBq in the toluene solution of 2mPCCzPDBq, the absorption peaks were observed at approximately 305 nm and 374 nm, and the emission wavelength peak was observed at 480 nm (excitation wavelength: 305 nm). As shown in FIG. 15, in the case of 2mPCCzPDBq in the thin film of 2mPCCzPDBq, the absorption peaks were observed at approximately 208 nm, 257 nm, 308 nm, 361 nm, and 379 nm, and the emission wavelength peak was observed at 515 nm (excitation wavelength: 380 nm).
