7650-91-1, Pt(tht)2Cl2 (synthesized according to a method disclosed in J. Chem. Soc., Dalton Trans. 1980, 888-894; 100 mg, 1 eq, ?tht? represents tetrahydrothiophene), benzyldiphenylphosphine purchased from Alfa Aesar (68 mg, 1.1 eq), and sodium acetate (94 mg, 5 eq) were added in a 50 mL round-bottomed flask, and degassed xylene (purchased from ECHOChemical; Product no: XA2101-000000-72EC; 6 mL) was then added therein with mixing to obtain a mixture, followed by heating to 100 C. and reacting for 12 hours. The mixture was then cooled to room temperature, and a precursor solution (PS1) of a phosphorescent four-coordinated platinum (II) complex was obtained. 4-(tert-butyl)-2-(3-(tert-butyl)-1H-pyrazol-5-yl)pyridine (59 mg, 1 eq) was added into the PS1 obtained from Synthesis Example 1 to obtain a mixture, and the mixture was heated to 100 C. and reacted for 6 hours, followed by cooling to room temperature and removing the solvent. Silica-gel column chromatography was conducted to purify the mixture using an eluent of dichloromethane and n-hexane (dichloromethane:hexane=1:1 (by volume)). Recrystallization was then conducted using dichloromethane/n-hexane so as to obtain a light yellow crystalline product, referred to as complex E2 (59.9% yield; 98.9 mg). The reaction scheme for producing the complex E2 is represented as follows: The spectrum analysis for the complex E2 is: 1H NMR (400 MHz, CD2Cl2, 298 K) delta 9.05 (d, J=7.6 Hz, 1H), 7.86-7.91 (m, 3H), 7.62 (d, J=2.0 Hz, 1H), 7.46-7.54 (m, 5H), 7.26-7.31 (m, 2H), 7.17 (d, J=7.0 Hz, 1H), 6.98-7.11 (m, 4H), 6.60 (s, 1H), 3.80 (d, J=11.4 Hz, 2H), 1.44 (s, 9H), 1.28 (s, 9H) ppm, 31P NMR (200 MHz, CD2Cl2, 298 K) delta 36.68 ppm, FAB-MS m/z 727.7 [M+1]+
