Metallo‐organic Conjugated Systems for Organic Electronics

Abstract

a] the extended life-time of the triplet state. This has successfully resulted in some high performance electronic devices containing metallo-organic p-conjugated small molecules and polymers. Herein, we review the recent advances made in metallo-organic materials (small molecules and polymers) for organic electronics.

Triazole‐fused indolo[2,3‐a]carbazoles: synthesis, structures, and properties

“…The conjugated molecular scaffolds having high planarity, structural rigidity, extended π conjugation, and compact molecular packing have found applications in the organic electronic devices such as organic solar cells (OSCs), [ 1–3 ] organic field effect transistors (OFETs), [ 4–6 ] and organic light emitting diodes (OLEDs). [ 7–9 ] In this regard, fused‐ring aromatic compounds such as acenes are found to be very effective. [ 10 ] However, poor solubility and oxidative instability of higher acene derivatives restrict their scope as potential materials in organic electronics.…”

New π-stacking motifs for molecular semiconducting materials: bis(bis(8-quinolinyl)amide)metal(ii) complexes of Cr, Mn, Fe, and Zn

“…Powder and thin film samples were dissolved in dichloromethane (DCM) prior to ESI-MS analysis. 1 H-Nuclear Magnetic Resonance (NMR) spectra were measured with a Bruker Advance III HD spectrometer at 400 MHz. Infrared (IR) Spectra were recorded on a Bruker Vertex 70 as thin films on BaF 2 .…”

“…[1][2][3] Alteration of the metal centre allows facile tuning of the electronic properties; phthalocyanine derivatives are prime examples in this context. 1,[4][5][6][7] Their charge carrier mobilities are amongst the highest reported in single crystalline samples as well as in thin film transistors. 1,8,9 Planar molecular structures are a common motif, often leading to stacking along one direction or in a herringbone type.…”

Copper Coordination Complexes for Energy-Relevant Applications

“…Organometallic luminescent emitters based on Ir, Pt or Os are widely used for OLEDs because of their color tunability, high efficiencies [3,4] and long-lived triplet excited states [58]. However, to meet the mass market production demand, these expensive noble metals have been replaced by luminescent complexes based on more abundant, non-toxic and cost effective metal complexes of copper.…”
