In the past years spirobifluorene-based molecules have been applied in different technological fields due to its chemical versatility.1 In particular, we recently showed that the spirobifluorene bearing two triphenylamine groups in position 2 and 7 produces blue ECL emission with quantum yield higher than the standard 9,10-diphenylanthracene.2 Although many ECL organic molecules have been investigated in solution, studies about the electrochemiluminescent properties in solid state of this kind of compounds are still limited. In this sense, research focused on the effect of surface functionalization attracts lot of interest in the ECL community. In order to investigate the ECL properties on solid state, we functionalized the surface of ITO electrode with a monolayer of spirobifluorene-based molecule using different approaches.

Abstract
In the past years spirobifluorene-based molecules have been applied in different technological fields due to its chemical versatility.1 In particular, we recently showed that the spirobifluorene bearing two triphenylamine groups in position 2 and 7 produces blue ECL emission with quantum yield higher than the standard 9,10-diphenylanthracene.2 Although many ECL organic molecules have been investigated in solution, studies about the electrochemiluminescent properties in solid state of this kind of compounds are still limited. In this sense, research focused on the effect of surface functionalization attracts lot of interest in the ECL community. In order to investigate the ECL properties on solid state, we functionalized the surface of ITO electrode with a monolayer of spirobifluorene-based molecule using different approaches. In this communication we report the characterization of self assembled monolayer covalently bound to the surface.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
