Nhepfenyuro ye bimetallic complexes ye ruthenium(II) yakavharwa neheterocyclic ligands yakaumbwa ne condensation ye4,5-diazafluoren-9-imwe ine madiamine akasiyana-siyana, hydrazine, 1,4-phenylenediamine, benzidine, uye 4,4'-methylenedianiline, inoguma nenzvimbo dzesimbi dzakaparadzaniswa nemadaro akasiyana.Iwo macomplexes anopa simbi-ku-ligand kuchaja-kutamisa kunyudzwa munharaunda ye450 nm yeinooneka spectrum uye intraligand pi --> pi shanduko munharaunda ye300 nm yeultraviolet spectrum.Nzvimbo dzeruthenium(II) dzakaiswa oxidized muzvikamu zviviri zvakaparadzana one-electron process pane zvingangoita zvakanaka pane zveRu(bpy)(3)(2+).Mabhuroko emagetsi anotapudzwa nemaitiro maviri akanyatsopatsanurwa erekitironi pane zvimwe zvakanaka zvinogoneka pane izvo zvekudzikisa zvakabatanidzwa bipyridine ligands (inenge -1.30 V), kunyangwe iyo diazafluorene=NN=diazafluorene bridging ligand yakaderedzwa zvakadzoreka mune maviri-elektroni. nhanho paE(1/2) kukosha kwe -0.29 uye -0.52 V. Mushure mekucheneswa kuburikidza nekuruting yakachena complexes pamusoro pe silica gel column ine zvakasiyana-siyana zve 0.10 M NH (4)PF (6) mu methanol, kubuda kunoitika chete mu girazi matrix pa 77 K uye pakudzika kwakadzika mumhinduro.Hupenyu hwekuburitsa pa77K mu4:1 ethanol:methanol girazi i5 +/- 1 &mgr;s.Kuchinja-kupisa kuburitsa kwehupenyu hwese kudzidza kunoratidza kuvepo kwenzvimbo yakaderera-yakadzika neDeltaE = ingangoita 1500 cm(-) (1), uye kuwedzeredza kune tembiricha yekamuri kunoratidza hupenyu hwekuburitsa huri mu subnanosecond renji.
