BACK TO BASICS SERIES: Compromise & Me! Being in Sweden: Lagom – Meeting in The Middle

Editor's Note: The Master Mediator is taking a break from his fascinating, in‐depth series on neuroscience and the psychological factors and cognitive biases that may affect dispute resolution. As Bob Creo's earliest columns, describing and discussing mediation room techniques and practice issues, appeared a number of years ago, and only on the CPR website, Alternatives is delighted that he has agreed to reprise and update them, beginning in this issue, in a new “Back to Basics” series. This column deals with the concept of compromise; future columns in the series will cover “ghostbusting” in mediation, terms of reference, and constructing settlements.     

Back to Basics Series: Ghostbusters & Me

Editor's Note: The Master Mediator is taking a break from his in‐depth series on neuroscience and the psychological factors and cognitive biases that may affect dispute resolution. As Bob Creo's earliest columns, describing and discussing mediation room techniques and practice issues, appeared only on the CPR website, he has agreed to reprise and update them for Alternatives, beginning with last month's issue, in a new “Back to Basics” series. Last month's column covered the concept of satisfactory compromise, while this one addresses “ghostbusting” in mediation. Future columns will cover such essentials as terms of reference and constructing settlements.     

Back to Basics: Legos and Me

Editor's Note: Master Mediator columnist Bob Creo has taken a break in the past two issues of Alternatives from his focus on neuroscience, psychological factors and cognitive biases that affect dispute resolution to revisit his past. He has returned to his earliest columns on mediation room techniques and practice issues—some nearly a decade old—and is reprising and updating them for a “Back to Basics” series. The articles are new to these pages, originally having appeared exclusively on the website of Alternatives' publisher, the International Institute for Conflict Prevention and Resolution. Last month's column faced “ghostbusting” in mediation—that is, dealing with the specters of “persons with influence over the outcome, but who are not physically present at the mediation session.” The November column covered the concept of satisfactory compromise. This month's column looks at the building blocks of a mediation resolution, literally. Still to come is a back‐to‐basics examination of constructing settlements.     

1,3,6,8‐Tetraphenylpyrene Derivatives: Towards Fluorescent Liquid‐Crystalline Columns?

Tetraphenylpyrene has been selected as a discotic core to promote liquid‐crystalline fluorescent columns in view of its high fluorescence quantum yield in solution and ease of substitution by flexible lateral side chains. The synthesis and characterization of ten new derivatives of pyrene have been carried out; the pyrene core has been substituted at the 1,3,6,8‐positions by phenylene rings bearing alkoxy, ester, thioether, or tris(alkoxy)benzoate groups on the para position; the compounds have been characterized by mass spectrometry and ¹H NMR and UV‐vis spectroscopies. In order to generate liquid‐crystalline phases, the nature, number, and size of the side chains as well as the degree of polarity around the tetraphenylpyrene core have been varied. However, the desired liquid‐crystalline behavior has not been observed. The supramolecular order together with the absorption and emission properties in solution and the solid state are discussed and compared to theoretical predictions. Quantum‐chemical calculations rationalize the high solid‐state fluorescence of a tetraphenylpyrene derivative for which the crystal structure has been determined.     

Alignment of a Perylene‐Based Ionic Self‐Assembly Complex in Thermotropic and Lyotropic Liquid‐Crystalline Phases

The thermotropic and lyotropic liquid‐crystalline (LC) phases of the ionic self‐assembled complex N,N′,‐bis(2‐(trimethylammonium)ethylene)‐perylene‐3,4,9,10‐tetracarboxyldiimide‐bis(2‐ethylhexyl)sulfosuccinate have been studied using polarizing microscopy, differential scanning calorimetry (DSC), and X‐ray scattering techniques. A two‐dimensional (2D) columnar thermotropic LC phase with π–π stacking of the perylene tectonic units and a lyotropic LC phase in dimethyl sulfoxide (DMSO) have been found. Different techniques have been applied to align both systems and included: surface interactions, electric and magnetic fields, shear force, and controlled domain formation at the LC–isotropic phase‐transition front (PTF). Characterization of the alignment in films has been performed using polarized UV‐vis spectroscopy and transmission null‐ellipsometry. The best results have been obtained for alignment of the material in a lyotropic phase by controlled domain formation at the PTF of the LC–isotropic phase transition. In this case, a dichroic ratio of 18 is achieved with packing of columns of perylenediimide tectons perpendicular to the PTF.     

Molecular Engineering of Host Materials for High‐Performance Phosphorescent OLEDs: Zig‐Zag Conformation with 3D Gridding Packing Mode Facilitating Charge Balance and Quench Suppression

A group of bipyridine/carbazole hybrid compounds, namely m‐BPyDCz, p‐BPyDCz, m‐BPySCz, and p‐BPySCz, are designed and developed as host materials for phosphorescent organic light‐emitting diodes (PhOLEDs). By tuning the p/n molar ratio and para‐/meta‐ substitution style, scorpion‐, Y‐, Z‐, and L‐shape molecular conformations are generated. In virtue of intermolecular hydrogen bonds and π–π interaction, these compounds form different molecular packing patterns in their single crystals. Particularly the Z‐shaped m‐BPySCz achieves 3D gridding packing with regular and ordered carbazole and pyridine columns as carrier hoping channels and larger intermolecular distance, which not only guarantees charge balance but also suppresses exciton quenching. Consequently the m‐BPySCz hosted sky‐blue and green PhOLEDs exhibit high external quantum efficiencies of 27.3% and 28.0% and low efficiency roll‐offs of 8.1% (at brightness of 1000 cd m^?2 for blue) and 14.3% (at 10000 cd m^?2 for green), all superior to other analogs and many reported host materials. The excellent performance of m‐BPySCz versus its lowest molecular weight and lowest amorphous stability manifests that the molecular packing style of host material dominates to determine the overall performance of PhOLEDs and the 3D gridding packing mode of zig‐zag conformation may be one ideal strategy to eliminate efficiency roll‐off in PhOLEDs.     

Epitaxial Ferroelectric Heterostructures with Nanocolumn‐Enhanced Dynamic Properties

The possibility to tailor ferroelectricity by controlling epitaxial strain in thin films and heterostructures of complex metal oxides is well established. Here it is demonstrated that apart from this mechanism, 3D film growth during heteroepitaxy can be used to favor specific domain configurations that lead to step‐like polarization switching and a giant nonlinear dielectric response in sub‐switching ac electric fields. A combination of cube‐on‐cube epitaxial growth and the formation of columnar structures during pulsed laser deposition of Pb_0.5Sr_0.5TiO₃ films on La_0.5Sr_0.5CoO₃ bottom electrode layers and MgO (001) substrates stabilizes ferroelectric nanodomains with enhanced dynamic properties. In the Pb_0.5Sr_0.5TiO₃ films, a‐ and c‐oriented epitaxial columns grow from the bottom to the top of the film leading to random polydomain architectures with strong associations between the ferroelectric domains and the nanocolumns. Polarization switching in the two domain populations is initiated at distinctive fields due to domain wall pinning on column boundaries. Moreover, piezoelectric coupling between ferroelectric domains leads to strong interdomain elastic interactions, which result in an enhanced Rayleigh‐type dielectric nonlinearity. The growth of epitaxial films with 3D columnar structures opens up new routes towards the engineering of enhanced ferroelectric and electromechanical functions in a broad class of complex oxide materials.
