Smart apex 2 ultra

General, Measurement, and Materials. 1 H, 19 F, and 13 C{ 1 H} NMR spectra were recorded using Bruker AVANCE-400 NMR spectrometer and AVANCE-600 NMR spectrometer. Elemental analyses were carried out using a Perkin-Elmer 2400 CHN elemental analyzer and Yanaco CHN coder MT-6 or MT-5. Anhydrous toluene and THF were purchased from Kanto Chemical and used as dry solvents. Crystal Structure Determination Intensity data were collected on a Bruker SMART APEX II ULTRA with Mo Kα radiation. UV-vis absorption spectra in solution states were recorded on a Hitachi U-3900H spectrophotometer. Excitation and emission spectra in solution states were recorded on a Hitachi F-2700 fluorescence spectrophotometer. The PL quantum yields of the emission were measured using a Hamamatsu Photonics C9920-02 absolute PL quantum yield spectrometer. UV-vis absorption spectra and photoluminescence spectra for the vacuum-deposited films were recorded on a Hitachi U-3010 and JASCO FP-6500 spectrophotometer, respectively. The HOMO energy level was estimated by photoelectron yield spectroscopy (PYS) using a Riken Keiki AC-3 spectrometer. Out-of-plane and in-plane XRD measurements were performed using MiniFlex600 and SmartLab diffractometer (Rigaku Corporation, Cu Kα radiation), respectively. The incident angle ω was set to 0.3° for in-plane measurement.
