All reagents were purchased from commercial suppliers and used as received. High-resolution ESI (HR-ESI) mass spectrometry spectra were acquired on a Thermo Scientific Q Exactive Mass Spectrometer. Elemental analysis was performed on a PerkinElmer 240C analyzer. The samples were dried under vacuum at 50 °C for 24 h to remove solvated molecules prior to elemental analysis. The 1H and 13C NMR spectra were obtained on a Bruker DRX-400 spectrometer. Coupling constants are given in hertz. UV-vis spectra were measured on a UV-3600 spectrophotometer. Photoluminescence (PL) spectra were measured with the Hitachi F-4600 PL spectrophotometer (λex = 420 nm). Circular dichroism (CD) spectra in CH2Cl2 solution were recorded on a Jasco J-810 spectropolarimeter at a scan rate of 100 nm min−1 and a resolution of 1 nm at room temperature. CPL spectra were recorded using a circularly polarizer on a Jasco CPL-300 spectrophotometer at a scan rate of 100 nm min−1 and a resolution of 1 nm at room temperature.
Cpl 300 spectrophotometer
Manufactured by Jasco
The CPL-300 spectrophotometer is a laboratory instrument designed to measure the absorbance or transmittance of light in a sample across a range of wavelengths. It is capable of analyzing the light absorption or emission properties of various materials and solutions.

Dichloromethane was used as solvent to dissolve the nanoclusters for UV-vis spectroscopy and a time-dependent UV-vis test was performed using a Metash UV-6000 spectrophotometer. The X-ray photoelectron spectroscopy (XPS) test was performed on an ESCALAB 250 high-performance electron spectroscopy instrument with a monochromatic Al-Kα (1486.8 eV) excitation source. An electrospray ionization mass spectrometry (ESI-MS) test was performed with a Waters Xevo G2-XSQ-TOF mass spectrometer. Single-crystal X-ray diffraction (SCXRD) was carried out on a STOE STADIVARI diffractometer, using graphite-monochromated Cu Kα radiation (λ = 1.54186 Å). Circular dichroism was analysed on a Biologic MOS-500 spectrophotometer. Tests on photoluminescence including fluorescence quantum yield and fluorescence lifetime were measured on an FL-4500 fluorescence spectrometer with a relative optical density of 0.1. Circularly polarized luminescence properties were measured on a JASCO CPL-300 spectrophotometer. Nuclear magnetic resonance (NMR) spectra were measured using a JEOL JNM-ECZ400S. Gas chromatography-mass spectra (GC-MS) were measured using a Thermo Fisher TSQ8000EVO.

All reagents were purchased from commercial suppliers and used as received (Caution: Perchlorates are potentially explosive and must be handled with great care and in small amounts. Collision and friction must be avoided.) Mass spectra were acquired on an LCQ Fleet ESI Mass Spectrometer. The NMR spectra were obtained on a Bruker DRX-500 spectrometer. Coupling constants are given in hertz. UV-Vis spectra were measured on a UV-3600 spectrophotometer. Elemental analysis was performed on a PerkinElmer 240C analyzer. Photoluminescence (PL) spectra were measured by using a Hitachi F-4600 PL spectrophotometer (λ ex = 420 nm). Luminescent quantum yields and lifetimes were measured on a HORIBA JY system. The electronic circular dichroism (ECD) spectra in CH 2 Cl 2 solution were recorded on a Jasco J-810 spectropolarimeter (using a 10 mm quartz cell for a concentration of 5 × 10 -5 mol L -1 ). The CPL spectra were recorded using a circular polarizer on a Jasco CPL-300 spectrophotometer at a scan rate of 100 nm min -1 and 1 nm resolution at room temperature (using a 10 mm quartz cell for a concentration of 5 × 10 -5 mol L -1 ). Mononuclear complexes (-)-(C^N^N)PtCl and (+)-(C^N^N)PtCl were prepared according to a previous method. 20 Compounds (+)-1 and (+)-2 were obtained using the same procedures as for (-)-1 and (-)-2, respectively.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
