Synthesis and bonding of trans-dichloro bis (L) ruthenium (III) chloride to a self assembled monolayer and its effect on conducting polymer sheet conductivity.

 

Our previous work has shown that Ru (II) complexes, possessing aromatic ligands, enhance sheet conductivity. Here we examine the effect that non-aromatic ligand have on conductivity. In this work, we report the monitoring of the synthesis of trans-Dichlorobis (L) ruthenium (III) chloride complexes (L; ethylenediammine, propyllenediammine and 1, 3-Diaminopropane). We then looked for UV broadened band at around 350nm for some low intensity components. This is a common absorption band in ruthenium (III) amine and haloamine complexes characteristic of a d-d transition. The complexes are then bonded to a self assembled monolayer on quartz, followed by deposition of conducting polymer PANI, PEDOT and Ppy. We will discuss key parameters which can be adjusted to tune both the physical properties of the Ru (III) surfaces and the sheet conductivity of the deposited conducting polymers thin films. This indirect structural method of tuning polymer conductivity can be extended to a wide variety of conducting polymers and a wide variety of substances.
