Compounds　2a-2f　were　synthesized　by　the　substitution　reaction　of　2-ferrocenyl-4,5-diphenylimi-dazole(1)　with　different　halohydrocarbons.　Then　compounds　2a-2f　were　reacted　with　iodomethane　to　get　compounds　3a-3f.　Finally,　compounds　3a-3f　were　exchanged　anion　with　ammonium　hexafluorophosphate　to　get　compounds　4a-4f.　All　these　compounds　were　structurally　characterized　by　means　of　infrared(IR),　mass　spectrometry(MS),　nuclear　magnetic　resonance(NMR),　high-resolution　mass　spectrometry(HRMS)　and　X-ray　crystal　diffraction.　Electrochemical　properties　of　these　compounds　were　studied　by　cyclic　voltammetry(CV).　Thermal　behavior　and　catalytic　performance　for　thermal　decomposition　of　ammonium　perchlorate(AP)　were　studied　by　thermogravimetric(TG)　and　differential　scanning　calorimetry(DSC).　The　results　indicate　that　all　the　synthetic　products　have　efficient　catalytic　effect　on　the　thermal　decomposition　of　AP.　The　iodized　salts(3a-3f)　indicate　better　catalytic　effect　than　the　hexafluorophosphate(4a-4f).　The　most　outstanding　compound　is　3b,　which　makes　the　second　decomposition　stage　of　AP　disappear,　and　the　first　stage　is　advanced　to　270.5　degrees　C.　The　novel　dinuclear　ferrocen-based　imidazolium　derivatives　would　have　great　value　in　preparing　high-burning-rate　catalyst　for　composite　solid　propellants.
