Jerin rukunin bimetallic na ruthenium (II) da aka haɗa ta hanyar haɗin gwiwar heterocyclic da aka kafa ta hanyar haɓakar 4,5-diazafluoren-9-daya tare da diamines daban-daban, hydrazine, 1,4-phenylenediamine, benzidine, da 4,4'-methylenedianiline, yana haifar da cibiyoyi na ƙarfe da aka rabu da nisa daban-daban.Rukunonin suna haifar da ɗaukar nauyin ƙarfe-zuwa ligand caji-canjawa a cikin yanki na 450 nm na bakan da ake iya gani da intraligand pi --> pi a cikin yanki na 300 nm na bakan ultraviolet.Cibiyoyin ruthenium (II) suna da iskar oxygen a cikin matakai guda biyu masu nisa tsakanin hanyoyin lantarki guda ɗaya a cikin abubuwan da suka fi dacewa fiye da na Ru (bpy) (3) (2+).An rage haɗin haɗin haɗin gwiwa ta hanyar matakai guda biyu masu nisa tsakanin hanyoyin lantarki guda ɗaya a mafi kyawun ma'auni fiye da na rage haɗin haɗin gwiwar bipyridine (kimanin -1.30 V), kodayake diazafluorene = NN = diazafluorene bridging ligand yana raguwa a cikin biyu-electron guda biyu. matakai a darajar E (1/2) na -0.29 da -0.52 V. Bayan tsarkakewa ta hanyar cire tsattsauran ra'ayi a kan ginshiƙin gel na silica tare da nau'i daban-daban na 0.10 M NH (4) PF (6) a cikin methanol, fitarwa yana faruwa ne kawai a cikin matrix na gilashi a 77 K kuma a ƙananan yanayin zafi a cikin bayani.Tsawon rayuwa a 77 K a cikin 4: 1 ethanol: gilashin methanol shine 5 +/- 1 & mgr;s.Wani bincike na rayuwa mai canzawa-zazzabi yana nuna kasancewar ƙasa mara ƙarfi tare da DeltaE = kusan 1500 cm(-) (1), kuma haɓakawa zuwa yanayin ɗaki yana nuna lokacin rayuwa yana cikin kewayon subnanosecond.
