“…A strong bathochromic shift of the long-wavelength maximum on going from solution to the solid state is a remarkable feature of hydrogen-bonded pigments [65][66][67][68][69][70][71][72][73][74]. This phenomenon, like the appearance of the J-band in aggregated dyes, is explained by the more efficient coupling of the transition dipole moments in the solid state compared with in solution.…”

“…High performance of the hydrogen-bonded pigments in photovoltaic devices and FET has been very recently demonstrated [70][71][72][73][74]. It was found, for example, that a quinacridone- Power conversion efficiencies as high as 0.83% have been recently demonstrated for bulkheterojunction solar cells fabricated with a soluble quinacridon precursor [75].…”

This review discusses some general aspects of the highly directional intermolecular interactions in organic solids, followed by an overview of π-conjugated systems exhibiting directional preference in the intermolecular connection and demonstrating enhanced energy and/or charge carrier transfer. As examples, "small" dyes and pigments, "intermediate-sized" N-heteroacenes, and "large" hydrogen-bonded oligomers are considered. In all of these systems the intermolecular interactions between polarized peripheries of the π-conjugated moieties ensure a preferential direction in the molecular packing. The most important among these interactions are hydrogen bonds (both strong and weak). As demonstrated recently, hydrogen bonding represents a dominant attractive force even for molecules with different polarization of the π-conjugated aromatic or heterocyclic moieties, considered to be the most favorable condition for "face-to-face" orientation (π−π stacking).The solid-state anisotropy, most likely, results from the nematic liquid-crystalline ordering of both thermotropic and lyotropic origin. Moreover, the unique efficiency of the exciton diffusion in the J-aggregates of dyes indicates significant potential of the nematic liquidcrystalline state itself for the design of organic semiconductors.

“…Besides, it was found that the generated adsorbate structures are temporally and thermally stable. Further, it can be said that the QAC arrays are chemically and mechanically resistant, [26][27][28][29][30][31][32] and can be built up within minutes or even seconds. [20][21] Additionally, previous investigations have shown, that alkyd resin can be used to seal a QAC adsorbate layer, providing a resistant protection layer without damaging the supramolecular structures.…”

“…We exemplify our approach using the organic semiconductor quinacridone (QAC), a cheap and commercially available pigment with promising electrical properties, low toxicity, excellent physical and chemical stability and biocompatibility for applications within the living organism. [26][27][28][29][30][31][32] The chemical structure of a single QAC molecule is shown in Fig. 1.…”

Growing low-dimensional supramolecular crystals directly from 3D particles

We show that one-dimensional (1D) nanostructures and two-dimensional (2D) supramolecular crystals of organic semiconductors can be grown on substrates under ambient conditions directly from three-dimensional (3D) organic crystals. The approach does not require dissolving, melting or evaporating of the source crystals and is based on the Organic SolidSolid Wetting Deposition (OSWD). We exemplify our approach by the pigment quinacridone (QAC). Scanning Tunnelling Microscopy (STM) investigations show that the structures of the resulting 2D crystals are similar to the chain arrangement of the alpha and beta QAC polymorphs and are independent of the 3D source crystal polymorph (gamma). Furthermore, distinct 1D chains can be produced systematically.

“…The semiconductors are used as gate-controlled charge transport material between the source and drain electrodes [23]. Additionally, natural chlorophyll, hemin, phenazine, terpenoid molecules and indigo (13a) are listed as natural p-and n-type semiconductors, whereas nature inspired materials such as indanthrene yellow G, brilliant orange RF, epindolidione (14), perylene diimide (15) [27] and also determined the charge carrier mobilities in the range of ~10 −4 cm 2 V −1 ·s −1 when applied in OTFTs. Ambipolar indigoids and quindacridones showed the most promising semiconductor properties due to their long-range order, crystallinity and highly dielectric characteristics.…”

Abstract:In recent years, both biodegradable and bio-based electronics have attracted increasing interest, but are also controversially discussed at the same time. Yet, it is not clear whether they will contribute to science and technology or whether they will disappear without major impact. The present review will address several aspects while showing the potential opportunities of bio-organic electronics. An overview about the complex terminology of this emerging field is given and test methods are presented which are used to evaluate the biodegradable properties. It will be shown that the majority of components of organic electronics can be substituted by biodegradable or bio-based materials. Moreover, application scenarios are presented where bio-organic materials have advantages compared to conventional ones. A variety of publications are highlighted which encompass typical organic devices like organic light emitting diodes, organic solar cells and organic thin film transistors as well as applications in the field of medicine or agriculture.
