Embodiment 1

[0031] (1)Cd 0.5 Zn 0.5 Preparation of S

[0032] Na 2 S (1.5608g, 20mmol) was dissolved in 40mL deionized water, and Cd(OAc) was added 2 2H 2 O (2.305g, 10mmol) and Zn(OAc) 2 2H 2 O (1.8348g, 10mmol) in 40mL of aqueous solution was stirred at room temperature for 24h. Then, the product was filtered, washed several times with deionized water, and dried in an oven at 80 °C for 5 h.

[0033] (2) Preparation of DTP

[0034] a: Place triptene (1.25g, 5mmol) in a three-necked flask, add concentrated HNO 3 50 mL, the mixture was heated and stirred at 75° C. for 24 h, and condensed under reflux. The reaction solution was a brown solution, which was cooled to room temperature, then poured into H 2 O (1000 mL) was stirred for 30 min. The precipitate was collected, washed with distilled water, and dried in air. The crude product was purified with dichloromethane / petroleum ether (1:1) as the eluent to give the white solid products 2,6,14-trinitrotriptene (2a) and 2,7,14-trin...
