Pre patterned ito substrates

Graphite powder (synthetic, conducting grade, 325 mesh, 99.9995%) was purchased from Alfa Aesar. RuCl₃.3H₂O, 2(2-Pyridyl) benzimidazole, aniline monomer and aluminium (Al) evaporation slug were procured from Sigma-Aldrich. Pre-patterned ITO substrates, PEDOT:PSS, P3HT, PTB7, PC₆₀BM and PC₇₀BM were purchased from OSSILA, Ossila Limited, Kroto Innovation Centre, Broad Lane, Sheffield, S3 7HQ, UK. All other solvents and reagents were received and used without further purification.

The electrospinning fiber precursor was poly (methyl methacrylate) PMMA (Mw = 350,000, Sigma Aldrich) 10 wt%, dissolved in dimethylformamide (DMF, ≥99.8%, Sigma-Aldrich). The PEDOT-PSS conductive polymer Al 4083, Hellmanex, and pre-patterned ITO substrates were purchased from Ossila. The IrQ(ppy)₂ emissive organometallic compound was synthesized in our laboratory and described previously [22 (link)]. The CBP electrically conductive and transparent material and dichloromethane (DCM) anhydrous were purchased from Sigma-Aldrich. Gold (99.99%) as the sputtering target was purchased from Kurt J. Lesker.
