Iskudhisyada bimetallic ee ruthenium (II) oo ay isku xidheen heterocyclic ligands oo ay sameeyeen uumi 4,5-diazafluoren-9-mid leh diamines kala duwan, hydrazine, 1,4-phenylenediamine, benzidine, iyo 4,4'-methylenedianiline, Natiijooyinka xarumaha birta ee kala fogaansho kala duwan.Dhismayaashu waxay dhaliyaan nuugista birta-ilaa-ligand-dallaca-wareejinta ee gobolka 450 nm ee muuqaalka muuqda iyo intraligand pi --> kala-guurka pi ee gobolka 300 nm ee spectrum ultraviolet.Xarumaha ruthenium(II) waxa ay oksaydhaysan yihiin laba hab oo korantada ah oo isku dhow oo kala fogaanaya iyaddoo laga yaabo in ay ka wanaagsan tahay tan Ru(bpy)(3)(2+).Isku-xidhka isku-xidhka ayaa lagu dhimay laba hab-socod oo isku dhow oo hal elektaroonig ah oo leh awood aad u wanaagsan marka loo eego hoos u dhigista isku-xidhka bipyridine ligands (qiyaastii -1.30 V), in kasta oo diazafluorene = NN = diazafluorene ligand ligand dib loo yareeyo laba hal-elektroonig ah. Tallaabooyinka E (1/2) qiyamka -0.29 iyo -0.52 V. Ka dib markii la nadiifiyo iyada oo la nadiifinayo dhismooyinka saafiga ah ee ka sarreeya tiirarka silica jel oo leh qiyaaso kala duwan oo ah 0.10 M NH (4) PF (6) ee methanol, qiiqa wuxuu ku dhacaa kaliya matrix muraayad ah oo ah 77 K iyo heerkulka hooseeya ee xalka.Cimrada sii daaya ee 77 K ee 4:1 ethanol: galaaska methanol waa 5 +/- 1 &mgr;s.Daraasad nololeed oo heerkul-bedel ah ayaa daaha ka qaadaysa joogitaanka xaalad-jiif ah oo leh DeltaE = ku dhawaad ​​1500 cm(-)(1), iyo ka saarista heerkulka qolka waxay muujineysaa in cimriga sii daayo uu ku jiro xadka hoose ee labaad.
