  • Scope and Optimization of the Double Knorr Cyclization: Synthesis of Novel Symmetrical and Unsymmetrical Tricyclic 1,8-Diazaanthraquinones
    作者:Dianqing Sun、Allan Prior
    DOI:10.1055/s-0036-1589134
    日期:2018.2
    thereof via double Knorr cyclization of di-β-ketoanilide precursor substrates is reported. The scope and generality of the double Knorr cyclization were investigated along with an optimization study. The double Knorr cyclization was found to be sensitive to steric bulk on precursor substrates. In addition, the presence of a 5-hydroxy group on the 1,3-di-β-ketoanilide facilitated the double Knorr cyclization

  • Dimensional, Pilling, and Abrasion Properties of Weft Knits Made from Open-End and Ring Spun Yarns
    作者:C. Candan、L. Önal

    日期:2002.2

    This paper focuses on the dimensional, pilling, and abrasion properties of a series of plain jersey, lacoste, and two-thread fleece fabrics made from cotton ring and open-end spun yams as well as from blend yams (50/50 cotton/polyester, dyed). The results show that both structural differences and fiber type play a large part in determining the dimensions of these fabrics. It is apparent that the knits from blend yams have a lower dimensional stability when compared to fabrics from 100% cotton ring and open-end spun yams. Findings for the two-thread fleece fabrics suggest that the inlay yam mainly governs their dimensional behavior in the widthwise direction. The pilling tendency of the test samples and their resistance to abrasion are evaluated with the ICI pilling box (at three different test revolutions) and the Martindale abrasion tester, respectively. In addition, an extensive SEM examination is used to study the effect of fiber type and repeated launder ings on both pilling development and the degree of fiber damage within fuzz assemblies. The results show that unlike plain jersey fabrics, lacoste fabrics perform very well, and that in general fabrics knitted from open-end spun yams have a lower propensity to pilling. In the case of the two-thread fleece structure, the samples from 100% cotton (i.e., both face and fleece yam) open-end yams have higher pilling rates compared to FBOE (face yam is cotton, fleece yam is 50/50 PET/cotton) and FBB (both face and fleece yam are 50/50 PET/cotton) fabrics. The SEM study reveals that for the same number of test revolutions, the degree of damage to fibers within the fuzz entanglements tends to increase with an increased number of launderings, and that the kind of damage varies from small cracks and fractures to slight flaking, depending on the fabric and yam type. Note, however, that any damage occurring as a result of repeated launderings and pilling tests is not as severe as that reported in the literature. The lacoste fabrics have the least resistance to abrasion.

    本文关注由棉纱和开口纱以及混纺纱(50/50棉/涤纶,染色)制成的一系列普通针织、拉科斯特和双线绒布织物的尺寸、起球和耐磨性能。结果显示,结构差异和纤维类型在决定这些织物尺寸方面起着重要作用。显然,与100%棉纱和开口纱制成的织物相比,混纺纱制成的针织织物具有较低的尺寸稳定性。双线绒布织物的研究结果表明,插入纱主要影响它们的宽向尺寸行为。测试样品的起球倾向和抗磨损性能分别通过ICI起球箱(在三种不同的测试转数下)和Martindale耐磨测试仪进行评估。此外,利用广泛的扫描电子显微镜检查了纤维类型和重复洗涤对起球发展和毛球组织内纤维损伤程度的影响。结果显示,与普通针织织物不同,拉科斯特织物表现非常出色,总体上,由开口纱制成的织物起球倾向较低。在双线绒布结构的情况下,100%棉(即正面和绒布纱)开口纱制成的样品与FBOE(正面纱为棉,绒布纱为50/50涤棉)和FBB(正面和绒布纱均为50/50涤棉)织物相比,起球率更高。SEM研究表明,在相同数量的测试转数下,随着重复洗涤次数的增加,毛球缠结内纤维的损伤程度往往增加,损伤的类型因织物和纱线类型而异,从小裂缝和断裂到轻微剥落不等。然而需要注意的是,任何由于重复洗涤和起球测试而导致的损伤并不像文献中报道的那样严重。拉科斯特织物对耐磨性最差。

  • The Power of Packing: Metallization of an Organic Semiconductor

    Benzoquino-bis-1,2,3-dithiazole 5 is a closed shell, antiaromatic 16 pi-electron zwitterion with a small HOMO-LUMO gap. Its crystal structure consists of planar ribbon-like molecular arrays packed into offset layers to generate a "brick-wall" motif with strong 2D interlayer electronic interactions. The spread of the valence and conduction bands, coupled with the narrow HOMO-LUMO gap, affords a small band gap semiconductor with sigma(RT) = 1 X 10(-3) S cm(-1) and E-act = 0.14 eV for transport within the brick-wall arrays. Closure of the band gap to form an all-organic molecular metal with sigma(RT) > 10(1) S cm(-1) can be achieved by the application of pressure to 8 GPa.
