All reagents were purchased from commercial sources and used without further purification unless otherwise stated. All experimental water used was deionized water.
1H and 13C NMR spectra were recorded on a Bruker AV 400 NMR spectrometer (Bruker, Switzerland) by using deuterated chloroform as solvent and tetramethylsilane as internal standard. High resolution mass spectrometry (HRMS) were obtained on a LCMS-IT-TOF high resolution mass spectrometer (Shimadzu, Japan). Fluorescence spectra were recorded on a HORIBA Fluorolog-3 high-sensitivity fluorescence spectrometer (HORIBA, Japan). Single crystal X-ray diffraction data were performed on a Bruker APEX-II CCD diffractometer. During the data collection process, the crystals was kept at 150 K.
