Abstract

This contribution describes the catalytic effect of heterolepticCu(I) complexes with pyrazino[2,3-f][1,10]phenanthroline-basedligands (C1-7) on the thermal decomposition of ammoniumperchlorate (AP). The complexes C2 and C4-7 were synthesizedand characterized by NMR, HRMS and, in the case of C7, by X-ray diffraction. The burning rate performance of C1-7 onthermal decomposition of AP was studied by differentialscanning calorimetry technique. The effect of the counter ion ype, the number of metal centers and ligand substitution wasevaluated. These AP+complex mixtures exerted a shift to lowerignition temperatures and an increase in the released heatsduring thermal decomposition compared with pure AP. Thecompound C4 showed the higher catalytic effect among thecomplexes series, and C5 exerted the highest energy release, incontrast to the other evaluated complexes and to the reportedcompounds CuO, [Cu2(en)2(HBTI)2]2and Catocene.
