Small molecule chemisorption on indium-tin oxide surfaces: Enhancing probe molecule electron-transfer rates and the performance of organic light-emitting diodes

Article Abstract:

Indium-tin oxide (ITO) surfaces are modified by chemisorption of carboxylic acid functionalized small molecules and the electron-transfer rate coefficients and the performance of organic light-emitting diodes (OLEDs) are examined. The results have confirmed the efficacy of small molecule chemisorption as a route to transparent conducting oxide (TCO) modification, creating a small polar surface, with increased electron-transfer rates to solution probe molecules but without the change in the effective work function of this associated with PEDOT:PSS (a poly(thiophene)/poly(stryenesulfonate) ITO modifier) treatments.

Electron-transport properties and use in organic light-emitting diodes of a bis(dioxaborine)fluorene derivative

Article Abstract:

The electron-transport (ET) properties that are the electronic, thermal, charge-transport, and electrical properties, of the bis(dioxaborine)fluorene (DOB) are investigated. The way in which a near-infrared (NIR) dopant can be used to fabricate a NIR-emitting organic light-emitting diode (OLED) using energy transfer from this exciplex/charge-transfer complex is shown.
