A new electrochemiluminescence (ECL) detector for capillary electrophoresis (CE) based on tris(2,2′-bipyridyl)ruthenium(II) (Ru(bpy) 32+ ) immobilized in Nafion/PTC-NH 2 (an ammonolysis product of 3,4,9,10-perylenetetracarboxylic dianhydride (PTCDA)) composite film was presented for the first time. The Nafion/PTC-NH 2 composite film could effectively immobilize tris(2,2′-bipyridyl)ruthenium(II)...
Three new compounds of Ga(III), Au(III), Sn(IV) with matrine (MT), [H-MT][GaCl 4 ] (1), [H-MT][AuCl 4 ] (2) and [Sn(H-MT)Cl 5 ] (3), have been synthesized and characterized by elemental analysis, IR, ESI-MS and single crystal X-ray diffraction methods. The crystal structural analyses indicate that 1 and 2 are ionic compounds, whereas 3 is a tin(IV) complex formed by the monodentate...
An effective method for immobilization of Ru(bpy) 32+ on glassy carbon electrode surface (GCE) is developed for the preparation of a novel electrochemiluminescence sensor. First of all, the positively charged Ru(bpy) 32+ is modified on the surface of negatively charged gold nanoparticles (nano-Au) via the electrostatic interactions to obtain the Ru(bpy) 32+ /nano-Au...
