Abstract
A novel amphiphilic Ru dinuclear complex, [(L18)Ru(tppz)Ru(L18)](4+), was s ynthesized and was introduced as a redox-active complex in Langmuir-Blodget t (LB) films, where L18 = 2,6-bis(2'-(1'-octadecylbenzimidazol))pyridine an d 2,3,5,6-tetrakis(2'-pyridyl)pyrazine (tppz). This Ru complex leads to a s table LB film formation and monolayers of this complex were transferred an glass and indium-tin oxide (ITO) substrates. The rr-A isotherm indicates an orientation of the complex with Ru-Ru axis nearly parallel to the substrat e surface. Two succesive one-electron oxidation processes were observed for the LB monolayer on ITO electrode.
