Embodiment 1
[0054] Sodium azide POSS (139.32g 90mmol), compound 2 (see reaction formula 1) (43.25g 120mmol), n-hexyne (39.36g 480mmol) and CuI (1.71g 9mmol) were added in the there-necked flask, and the N 2 DMF10ml was added under atmosphere, and stirred at room temperature for 12 hours. After the initial product was filtered, it was successively washed with CHCl 3 , MeOH, H 2 O, THF, Et 2 O washed and dried under vacuum at 40°C for 12 hours. The molecular formula of the product is: (C 30 Si 2 N 8 o 2 h 28 ) 12 (C 9 SiN 3 Oh 18 ) 48 (Si 8 o 12 ) 9 , Yield 92%, Luminescence peak wavelength: 540nm.
