Three dinitro heteroaromatic ring-fused pyridazines,4,7-dinitrofurazano[3,4-d]pyridazine (DNFP),4,7-dinitrofuroxano[3,4-d]pyridazine (DNFOP)and 5,8-dinitropyridazino [4,5-e][1 ,2,3,4 ]tetrazine 1,3-dioxide (DNPTDO)were designed.On the basis of the stable geometries optimized at B3LYP/6-31G** theoretical level, the Wiberg bond order,bond dissociation energy (BDE),electrostatic potential,theoretical density and solid state phase heats of formation of title compounds were calculated at the same theoretical level.The detonation velocities (D),detonation pressures (p )and the performances of these compounds as monopropellants were predicted by Kamlet-Jacobs formula and the minimum free energy method,respectively.The results show that the BDE,ρ,D , and p of DNFOP are 80.37 kJ/mol,1.939 g/cm3 ,9 151 m/s,and 39.54 GPa,respectively,and the BDE,ρ,D ,and p of DNPTDO are 208.59 kJ/mol,1 .942 g/cm3 ,9 235 m/s,and 40.30 GPa,respectively,while DNFP presents relatively lower detonation velocity (8 811 m/s)and detonation pressure (36.27 GPa).As monopropellants,specific impulse of DNFP,DNFOP and DNPTDO are higher than that of RDX by 97.6,120.6 and 140.6 N·s/kg,respectively.
