A simple structured and efficient triazine-based molecule as an interfacial layer for high performance Organic Electronics
Energy & Environmental Science, 2016Co-Authors: Nallan Chakravarthi, Antonio Facchetti, Kumarasamy Gunasekar, Woosum Cho, Dang Xuan Long, Yun-hi Kim, Chang Eun Song, Jong-cheol Lee, Myungkwan Song, Yong-young NohAbstract:Achieving the state-of-the-art performance of solution processable and flexible Organic Electronics requires efficient, stable, and cost-effective interfacial layers (ILs). Here, we report an alcohol soluble phosphine oxide functionalized 1,3,5-triazine derivative (PO-TAZ) as an IL, which remarkably tailors the work function of conductors including metals, transparent metal oxides and Organic materials, making it an ideal candidate for an interfacial material in Organic Electronics. Consequently, PO-TAZ thin films enable the fabrication of Organic and Organic–inOrganic (perovskite) solar cells with power conversion efficiencies of 10.04% and 16.41%, respectively, and n-channel Organic field-effect transistors with an electron mobility of 8 cm2 V−1 s−1. Owing to the low-cost processing associated with PO-TAZ and the tremendous improvement in device performances as compared to the devices without PO-TAZ along with ambient stability, PO-TAZ is a good choice for efficient Organic Electronics in large area printing processes.

gate dielectrics for Organic field effect transistors new opportunities for Organic Electronics
Advanced Materials, 2005Co-Authors: Antonio Facchetti, Myunghan Yoon, Tobin J MarksAbstract:In this contribution we review the motivations for, and recent advances in, new gate dielectric materials for incorporation into Organic thin-film transistors (OTFTs) for Organic Electronics. After a general introduction to OTFT materials, operating principles, and processing requirements for optimizing low-cost Organic Electronics, this review focuses on three classes of OTFT-compatible dielectrics: i) inOrganic (high-k) materials; ii) polymeric materials; and iii) self-assembled mono- and/multilayer materials. The principal goals in this active research area are tunable and reduced OTFT operating voltages, leading to decreased device power consumption while providing excellent dielectric/insulator properties and efficient low-cost solution-phase processing characteristics.

Rylene and related diimides for Organic Electronics
Advanced Materials, 2011Co-Authors: Xiaowei Zhan, Antonio F. Facchetti, Stephen Barlow, Michael R Wasielewski, Mark A Ratner, Tobin J Marks, Stephen R MarderAbstract:Organic electron-transporting materials are essential for the fabrication of Organic p-n junctions, photovoltaic cells, n-channel field-effect transistors, and complementary logic circuits. Rylene diimides are a robust, versatile class of polycyclic aromatic electron-transport materials with excellent thermal and oxidative stability, high electron affinities, and, in many cases, high electron mobilities; they are, therefore, promising candidates for a variety of Organic Electronics applications. In this review, recent developments in the area of high-electron-mobility diimides based on rylenes and related aromatic cores, particularly perylene- and naphthalene-diimide-based small molecules and polymers, for application in high-performance Organic field-effect transistors and photovoltaic cells are summarized and analyzed.

Conjugated Polymer–Porphyrin Complexes for Organic Electronics
Chemphyschem : a European journal of chemical physics and physical chemistry, 2015Co-Authors: Rolf E. Andernach, Iain Mcculloch, Stephan Rossbauer, Raja Shahid Ashraf, Hendrik Faber, Thomas D. Anthopoulos, Martin Heeney, Hugo BronsteinAbstract:We present the synthesis of novel conjugated polymer–porphyrin complexes for use in Organic Electronics. Linear and star-shaped platinated porphyrins were attached to regioregular poly(3-hexylthiophene-2,5-diyl) (P3HT) arms to investigate whether porphyrin stacking and increased dimensionality can be used to control polymer morphology. The novel materials display similar optical properties to P3HT, but give higher mobilities when used in Organic field-effect transistors. Atomic force microscopy measurements show that incorporation of only a small amount of porphyrin into the conjugated polymer backbone leads to increased aggregation. These materials demonstrate that polymer morphology and performance can be tuned and enhanced effectively through the use of conjugatively linked porphyrins.

Synthesis of two dihydropyrroloindoledione-based copolymers for Organic Electronics
Journal of Polymer Science Part A: Polymer Chemistry, 2012Co-Authors: Joseph W. Rumer, Sheng Yao Dai, Matthew Levick, Laure Biniek, David J. Procter, Iain MccullochAbstract:Two novel dihydropyrroloindoledione (DPID)-based copolymers have been synthesized in a two directional approach and characterized (gel permeation chromatography (GPC), ultra- violet-visible (UV-vis), cyclic voltammetry, and computational models). These planar, broad absorption copolymers show promise for use in Organic Electronics, with deep energy levels and low bandgaps. The two-directional Knoevenagel condensa- tion used demonstrates the versatility of DPID as a useful yet underexploited conjugated unit. V C 2012 Wiley Periodicals, Inc. J. Polym.
