Quintic trigonometric Bézier curve with two shape parameters

The fifth degree of trigonometric Bézier curve called quintic with two shapes parameter is presented in this paper. Shape parameters provide more control on the shape of the curve compared to the ordinary Bézier curve. This technique is one of the crucial parts in constructing curves and surfaces because the presence of shape parameters will allow the curve to be more flexible without changing its control points. Furthermore, by changing the value of shape parameters, the curve still preserves its geometrical features thus makes it more convenient rather than altering the control points. But, to interpolate curves from one point to another or surface patches, we need to satisfy certain continuity constraints to ensure the smoothness not just parametrically but also geometrically

Electrode Doping and Dielectric Effect in Hole Injection into Organic Semiconductors through High Work-Function Oxides

High work-function metal oxides are common for enhancing hole injection into organic semiconductors. However, the current understanding of the electrostatic mechanism needs to be more consistent with materials’ electronic properties. Here, we study the electrostatic profile of high work-function oxides by considering their dielectricity and energetic disorder. Using MoO3 as an example, we first show that the significant vacuum-level change at the electrode–oxide interface originates from electrode doping rather than the conventionally assumed interface dipole. Moreover, electrode doping is enough to explain the Fermi-level shift, so MoO3’s characteristic n-type property is not necessarily due to intrinsic donors. This conclusion also applies to the n-type oxides with reduced work functions, like WO3, V2O5, and p-type NiO. Finally, the dielectricity of the oxide, either n-type or p-type, reduces the surface p-doping of the further deposited organic layer. Increasing the oxide’s metallicity and energetic disorder facilitates the hole injection

Heterobimetallic Lanthanide/Sodium Phenoxides: Efficient Catalysts for Amidation of Aldehydes with Amines

Heterobimetallic lanthanide/sodium phenoxides were found to be efficient catalysts for amidation of aldehydes with amines under mild conditions. The reactivity follows the order Nd 2C6H3O iPr)2C6H3O tBu)2C6H3O for phenoxide groups. In comparison with the corresponding monometallic complexes, heterobimetallic complexes show higher activity and a wider range of scope of amines. A cooperation of lanthanide and sodium in this process is proposed to contribute to the high activity of the present catalyst

Synthesis, Reactivity, and Structural Characterization of Sodium and Ytterbium Complexes Containing New Imidazolidine-Bridged Bis(phenolato) Ligands

A new imidazolidine-bridged bis(phenol) [ONNO]H2 ([ONNO]H2 = 1,4-bis(2-hydroxy-3,5-di-tert-butyl-benzyl)imidazolidine) was prepared in relatively high yield by Mannish reaction of 2,4-di-tert-butylphenol, formaldehyde, and ethylenediamine in a 2:3:1 molar ratio. Reaction of the bis(phenol) with NaH in THF, after workup, afforded the sodium bis(phenolate) {[ONNO]Na2(THF)2}2·2THF (1) as a dimeric tetranuclear complex in an almost quantitative yield. Reaction of YbCl3 with complex 1 in a 2:1 molar ratio in THF, in the presence of HMPA, produced the desired bis(phenolate) ytterbium dichloride as bimetallic complex [ONNO]{YbCl2(HMPA)}2·2.5C7H8 (2). Complex 2 can be used as a precursor for the synthesis of ytterbium derivatives by salt metathesis reactions. Reaction of complex 2 with NaOiPr in a 1:2 molar ratio in THF led to the formation of bimetallic alkoxide [ONNO]{Yb(μ-OiPr)Cl(HMPA)}2·THF (3). However, the residual chlorine atoms in complex 3 are inactive for the further substituted reaction. Further study revealed that the bulkiness of the reagent has profound effect on the outcome of the reaction. Complex 2 reacted with bulky NaOAr (ArO = 2,6-di-tert-butyl-4-methylphenoxo) or NaNPh2 in a 1:2 molar ratio under the same reaction conditions, after workup, to give the ligand redistributed products, (ArO)2YbCl(HMPA)2 (4) and [ONNO]YbCl(HMPA)2 (5) for the former and complexes 5 and (Ph2N)2YbCl(HMPA)2 (6) for the latter. If the molar ratio of complex 2 to NaNPh2 decreased to 1:4, the expected ligand redistributed products [ONNO]YbNPh2(HMPA) (7) and (Ph2N)3Yb(HMPA)2·C7H8 (8) can be isolated in high yields. All of the complexes were well characterized, and the definitive molecular structures of complexes 1−4, 7, and 8 were provided by single-crystal X-ray analysis
