“…Materials can also be prepared by sequential synthesis/self-assembly techniques and by crystal growth including from solution, the melt and the vapor phase [97][98][99][100][101][102][103][104][105][106][107]; however, these approaches have not been as widely adapted to the fabrication of prototype devices as have electric field poling methods.…”

Integrated (multi-scale) quantum and statistical mechanical theoretical methods have guided the nano-engineering of controlled intermolecular electrostatic interactions for the dramatic improvement of acentric order and thus electro-optic activity of melt-processable organic polymer and dendrimer electro-optic materials. New measurement techniques have permitted quantitative determination of the molecular order parameters, lattice dimensionality, and nanoscale viscoelasticity properties of these new soft matter materials and have facilitated comparison of theoretically-predicted structures and thermodynamic properties with experimentally-defined structures and properties. New processing protocols have permitted further enhancement of material properties and have facilitated the fabrication of complex device structures. The integration of organic electro-optic materials into silicon photonic, plasmonic, and metamaterial device architectures has led to impressive new performance metrics for a variety of technological applications.

“…The approach was recently widely utilized to control supramolecular organization in reversible media (34)(35)(36) and also to create tightly packed molecular assemblies for electronic and optoelectronic applications (37,38). Although some other non-covalent interactions were well investigated for the realization of supramolecular self-assembled structures for use in NLO applications (39)(40)(41)(42), there are few reports concerning the use of the Ar H -Ar F interaction in EO materials to both assist dipole alignment during electric-filed poling and provide physical cross-linking for lattice hardening.…”

Arene-perfluoroarene stacking interactions are explored in a new series of dendronized nonlinear optical (NLO) chromophores to create extended network structures and overcome intermolecular electrostatic interactions for improving their poling efficiency and alignment stability. These supramolecular self-assembled molecular glasses showed ultrahigh electro-optic (EO) activity (r 33 > 300 pm/V) and excellent thermal stability (at 85°C). These unprecedented EO activities could inspire the vigorous development of new integrated optical devices.Organic and polymeric electro-optic (EO) materials have been intensively studied for several decades due to their potential applications for the high speed/broad bandwidth information technologies (1-3), terahertz radiation generation and detection (4, 5), integrated circuitry, and multifunctional microand nanodevices (6-8). Their development is motivated not only by the large nonlinear optical (NLO) susceptibilities, but also by the versatility, ease of processability, and possibility of tailoring the physicochemical properties through In Organic Thin Films for Photonic Applications; Herman, W., et al.; ACS Symposium Series; American Chemical Society: Washington, DC, 2010.molecular engineering. Recently, significant advances (9, 10) in the design and synthesis of new-generation organic EO materials have led to the successful demonstration of ultralarge EO coefficients (r 33 values) of greater than 300 pm/V. This breakthrough result allowed organic NLO materials to significantly surpass the EO properties of lithium niobate, the dominant inorganic material currently used in modern EO modulator technology. These materials with such high EO activities and unprecedented performance in conventional device formats provide a powerful platform for building innovative devices such as hybrid systems using EO polymers integrated with silicon photonics (11,12).

“…For small molecules, the most commonly utilized method is organic molecular beam deposition (OMBD) (see Fig. 4(a)) whereby organic molecules are evaporated onto a thermally stabilized substrate under high or ultrahigh vacuum (UHV) conditions [23]. An alternative technique where small molecules are deposited onto a range of substrates is organic vapor-phase deposition [24] where the molecules are transported to the substrate by means of a carrier gas.…”

Herein, we describe a number of key issues that concern the commercialization of organic light-emitting diodes for display applications. We will firstly outline the historical and market contexts that show the potential for organic electronics as a viable display technology. Next, we will discuss the chemical structures for a range of both smallmolecular and polymer organic semiconducting compounds, and how the electronic properties are governed thereof. Also we will briefly discuss various common film deposition and device fabrication strategies. Then, we will describe two factors that are highly relevant for commercially viable organic light-emitting diodes, namely charge balance, and device degradation. Finally, we will outline some methods for achieving the high-volume throughput of organic electronics via well-established technologies that are used in the printing industry.
