1 H and C NMR spectra were obtained on a BRUKER AMX 500-MHz instrument. High-resolution mass spectra were recorded using a Xevo G2-XS Q-Tof Mass spectrometer. The UV-Vis absorption spectra of the compounds were acquired by a Perkin Elmer Lambda 365. The photoluminescence emission spectra, the lifetime and time-resolved emission spectra of the solution, and film samples were recorded using an Edinburgh FLS1000 luminescence spectrophotometer equipped with a xenon arc lamp (Xe 900), a picosecond laser. The PL quantum efficiency was measured on Quantaurus-QY C11347-11. Circular dichroism spectroscopy was collected on Applied Photophysics Chirascan. CPL spectra were performed with a JASCO CPL-300 spectrometer.
