  Deep-blue emitting poly(2′,3′,6′,7′-tetraoctyl-2,7-spirosilabifluorene) simultaneously with good color purity and high external quantum efficiency

  摘要：

  A deep-blue emitting poly(2',3',6',7'-tetraoctyl-2,7-spirosilabifluorene), namely PSSiBF, has been newly developed for PLEDs. Unlike the previously-reported alkyl-functionalized P27SiF, the unwanted aggregation can be effectively prevented in PSSiBF due to the perpendicular arrangement between two spiro-linked dibenzosilole moieties. Compared with P27SiF (Phi(PL)=0.62), consequently, an improved PLQY of 0.84 is obtained for the film of PSSiBF accompanied by a significant reduction of the long-wavelength emission in the range of 450-550 nm. Based on a double-layer device configuration, PSSiBF gives a bright deep-blue electroluminescence, revealing a state-of-art EQE of 2.8% and CIE coordinates of (0.16, 0.06). The simultaneous realization of good color purity and high EQE clearly implies that the silicon-containing polymers do have the great potential in efficient PLEDs.

• Intramolecular strong electronic coupling in a discretely H-aggregated phthalocyanine dimer connected with a rigid linker

  accurate assembly of phthalocyanines is rather difficult because of the high aggregation property of phthalocyanines. In this study, a novel discrete phthalocyanine dimer was prepared in which the relative configuration of each component was tightly and accurately fixed in an H-aggregate form by a rigid U-shaped linker. Electrochemical measurements showed that there were strong intramolecular electronic interactions

  由于酞菁的高聚集性质，制备精确组装的酞菁是相当困难的。在这项研究中，制备了一种新颖的离散的酞菁二聚体，其中每个组分的相对构型通过刚性U形接头牢固而精确地固定为H聚集体形式。电化学测量表明，两种酞菁之间存在强烈的分子内电子相互作用。
• Formal Aryne Polymerization: Use of [2.2.1]Oxabicyclic Alkenes as Aryne Equivalents

  Despite the high utility of aryne in organic synthesis, its polymerization has long been a significant challenge in polymer chemistry. A critical bottleneck in this process is the intrinsic instability of aryne and consequent short lifetime for polymerization. In order to circumvent the problem, we focus on a synthetic equivalent of aryne, [2.2.1]oxabicyclic alkene, as a monomer for polymerization. Palladium-catalyzed coordination insertion polymerization of [2.2.1]oxabicyclic alkenes produced the corresponding polymers having an aliphatic main chain.. Subsequent acid-promoted dehydration allowed the aliphatic main chain to be converted into an aromatic main chain to form poly(o-arylene)s. These sequential processes represent the first formal aryne polymerization, which offers an efficient method to synthesize a variety of poly(o-arylene)s in a chain-growth polymerization manner.
