“…OLEDs have been available in the commercial market and have achieved highly efficient performance of RGB (red-green-blue) color and white light displays. [6][7][8] OSCs and OLEDs with efficient and stable performance have been reported using different metal oxides as the electron and hole transport layers (ETLs and HTLs). Metal oxides with a high work function such as MoO 3 , 9,10 V 2 O 5 , 11 WO 3 12,13 and NiO x 14,15 can function as HTLs in organic optoelectronic devices to address the degradation issue of poly (3,4-ethylenedioythiophene):poly(styrenesulfonate) (PEDOT:PSS)-based devices.…”

MoOx and V2Ox as hole and electron transport layers through functionalized intercalation in normal and inverted organic optoelectronic devices

To achieve fabrication and cost competitiveness in organic optoelectronic devices that include organic solar cells (OSCs) and organic light-emitting diodes (OLEDs), it is desirable to have one type of material that can simultaneously function as both the electron and hole transport layers (ETLs and HTLs) of the organic devices in all device architectures (i.e., normal and inverted architectures). We address this issue by proposing and demonstrating Cs-intercalated metal oxides (with various Cs mole ratios) as both the ETL and HTL of an organic optoelectronic device with normal and inverted device architectures. Our results demonstrate that the new approach works well for widely used transition metal oxides of molybdenum oxide (MoO x ) and vanadium oxide (V 2 O x ). Moreover, the Cs-intercalated metaloxide-based ETL and HTL can be easily formed under the conditions of a room temperature, water-free and solution-based process. These conditions favor practical applications of OSCs and OLEDs. Notably, with the analyses of the Kelvin Probe System, our approach of Cs-intercalated metal oxides with a wide mole ratio range of transition metals (Mo or V)/Cs from 1 : 0 to 1 : 0.75 can offer significant and continuous work function tuning as large as 1.31 eV for functioning as both an ETL and HTL. Consequently, our method of intercalated metal oxides can contribute to the emerging large-scale and low-cost organic optoelectronic devices.

“…Since then, enormous progress has been made in the macromolecular engineering of the !-conjugated polymers and in their uses as active materials in polymeric light-emitting diodes (PLEDs) [2][3][4][5][6]. These polymers are promising organic analogues of inorganic semi-conducting materials, and their exploitation in other electronic devices, such as thin-film transistors [7,8], photovoltaic cells [9,10], chemical sensors [11] and organic lasers [12] are currently expanding.…”

Abstract. New conjugated PPV derivatives containing the chiral isosorbide group (P1-3) have been synthesized via the Gilch reaction. The polymers are optically active, soluble in common organic solvents and show good film-forming abilities. High number-average molecular weights were determined by size exclusion chromatography (SEC) (16·10 3 -21·10 3 g·mol -1 ). The molecular structures of the polymers were confirmed by nuclear magnetic resonance (NMR) and Fourier transform infrared (FTIR) spectroscopies. Thermogravimetric analysis of the polymers showed good thermal stability up to 320°C. The optical properties of these !-conjugated materials were investigated by UV-vis absorption and photoluminescence (PL) spectroscopies. The polymers show a yellow fluorescence in dilute solution, and an orange emission is observed in thin films. The introduction of the polar isosorbide groups improved the PL intensity, and quantum yields between 50 and 73% were obtained. The HOMO-LUMO energy levels were estimated by cyclic voltammetry, and the electrochemical gaps were 1.81, 1.83 and 2.48 eV for P1, P2 and P3, respectively. Single-layer diode devices were fabricated and show relatively low turn-on voltages between 3.1 and 3.4 V.

This intractability has been addressed by chemically attaching aliphatic side-chains to the polymer backbone [19]. Hence, many PPV-type architectures are processed in a derivative form. The effects of the side-group structure on the opto-electronic properties have been extensively investigated [20]. However, most studies have involved nonpolar sidechains, and the effect of relatively polar side-groups was rarely reported (e.g PPV derivative containing ethylene oxide-type side chains) [12]. Here, we report the first PPV derivatives containing the polar and chiral isosorbide groups. In fact, the incorporation of chiral groups in polypyrroles and polythiophenes was reported. These groups confer original physico-chemical properties to the polymer [21][22][23]. Therefore, these optically active polymers were used to prepare chiral electrodes for asymmetric electrosynthesis, polarization-sensitive electro-optical devices, polarized photo-and electroluminescent devices and enantioselective sensors [24]. Herein, we present the synthesis and structural characterizations of the isosorbide-containing PPVs; the thermal, thin film surface, optical and electrochemical properties were investigated.
