Iodide-Mediated or Iodide-Catalyzed Demethylation and Friedel–Crafts C–H Borylative Cyclization Leading to Thiophene-Fused 1,2-Oxaborine Derivatives
摘要:
The first synthesis of dithieno-1,2-oxaborine derivatives was achieved via iodide-mediated or iodide-catalyzed demethylation of 3-methoxy-2,2'-bithiophene and subsequent C-H borylation. A wide variety of thiophene-fused oxaborines could be synthesized by the procedure.

We report the first example of a general, exhaustive Pd-mediated cross-coupling of polychloroarenes in the presence of a deficit of nucleophiles, mediated by the highly active PEPPSI-IPent catalyst.

A series of small-sized model π-conjugated oligomers have been prepared from thienylene and phenylene or dimethylor dimethoxy-substituted phenylene units. Crystallographic data for the methoxylated compound show a quasi-planar conformation with a non-covalent S–O interaction. The resulting strong conjugation in the gas phase has also been highlighted by UV/photoelectron spectroscopy and theoretical

The present invention generally relates to the field of conducting polymers. More specifically, the present invention relates to polymerisable monomers comprising a probe capable of binding one or more nucleic acids or comprising a nucleic acid or an analogue thereof, conducting polymers comprising monomer units of such monomers, and methods of making such polymers. The present invention also relates to sensors comprising the polymers, sensor systems comprising the sensors, methods of making the sensors, and methods for determining the presence or absence or amount of targets employing the sensors. The present invention also relates to methods, systems and apparatuses for amplifying nucleic acids employing the conducting polymers.
Volatile solid additives (SADs) are considered as a simple yet effective approach to tune the film morphology for high-performance organic solar cells (OSCs). However, the structural effects of the SADs on the photovoltaic performance are still elusive. Herein, two volatilizable SADs were designed and synthesized. One is SAD1 with twisted conformation, while the other one is planar SAD2 with the S···O
挥发性固体添加剂(SAD)被认为是调节高性能有机太阳能电池(OSC)薄膜形态的简单而有效的方法。然而,SAD 对光伏性能的结构影响仍然难以捉摸。在此,设计并合成了两种挥发性SAD。一种是具有扭曲构象的SAD1,另一种是具有S·O非共价分子内相互作用(NII)的平面SAD2。理论和实验结果表明,占据较小空间的平面SAD2更容易插入Y6分子之间,有利于热处理后Y6形成更紧密的分子间堆积模式。结果,经过SAD2处理的OSC表现出更少的复合损失、更平衡的电荷迁移率、更高的空穴传输率和更有利的形貌,从而实现了创纪录的18.85%的功率转换效率(PCE)(认证PCE:18.7%)。单结二元 OSC。这项研究的普遍性有助于理解 SAD 对 OSC 光伏性能的构象影响。
