  一种有机电致发光材料、应用及器件

  摘要：

  本发明涉及一种有机电致发光材料，其由下式(I)所示：其中，Ar1为三芳胺类共轭基团。其选择吡嗪并喹喔啉作为母体，刚性碳骨架均在一个共平面上，有利于电子及空穴传输，通过引入炔基、氰基，提高了吡嗪并喹喔啉的电子传输性能；通过在炔基上引入具有良好空穴传输性能的三芳胺类化合物，使其兼具空穴及电子传输性能。因此，该有机电致发光材料具有较高的空穴及电子传输性能，较强的抗氧化能力，以及较高的玻璃化温度，容易形成良好的无定形薄膜，其可被应用在有机电致发光领域，作为有机材料的发光层和/或电子传输层和/或空穴传输层使用。

• Host-guest complexation. 61. C- and Z-shaped ditopic cavitands, their binding characteristics, and monotopic relatives
  作者：Donald J. Cram、Linda M. Tunstad、Carolyn B. Knobler

  Readily available octol 1, when treated with 3 mol of CH2ClBr, gave hexol 2 (3%), tetrol 3 (7%), diol 4 (17%), and tetra-bridged 5 (10%). The tetrol and diol served as starting materials for preparing mixed-bridged systems. Diol 4 reacted with 2,3-dichloroquinoxaline (7) to give 7% of cavitand 8, whereas tetrol 3 reacted with only one of the 2 mol of quinoxaline 7 to give the chiral diol 9 (18%). When 2 mol of diol 4 were treated with 1 mol of fluoranil (6), the mixture of 42% of Z-shaped 10 (Z-10) and 12% of C-shaped 10 (C-10) produced was easily separated. The crystal structures of 4.CHCl3.H2O, C-10.3CH3CN.CH2Cl2, Z-10.4CH3CO2CH2CH3, Z-10.4CH3COCH2CH3, and Z-10.6C6H5NO2 were determined and found to resemble what was predicted from molecular model examination. When 1 mol of diol 4 was mixed with tetrachlorotetraazaanthracene 12, a 16% yield of what is probably Z-11 was obtained. One-to-one association constants of C-10 in CD2Cl2 at 21-degrees-C were determined by H-1 NMR titrations with guests as follows: C6D5NO2 (K(a) = 0.6 M-1), C6D5CD3 (K(a) = 1.8 M-1), p-CD3C6D4CD3 (K(a) = 1.6), and CH3COCH2CH3 (K(a) = 1.2 M-1). Attempts to detect binding failed with 2-butyne, 2-pentyne, and methylcyclohexane, although molecular model examination suggested that all seven of the above guests are complementary to the highly preorganized ditopic cavity of C-10.
• Hinged Molecular Capsules:  Synthesis and Conformational Control via Temperature, pH, or Solvent Composition
  作者：Sang-Woo Kang、Peter P. Castro、Gang Zhao、Jose E. Nuñez、Carlos E. Godinez、Linda M. Gutierrez-Tunstad

  DOI：10.1021/jo0521807

  日期：2006.2.1

  Three new covalently linked molecular capsules were synthesized from their resorcinarene cavitand precursors in good yields. The capsules undergo reversible conformational switching between the closed "vase" form and the open "kite" form upon temperature or pH variation. The kite conformation obtained via either method in CDCl(3) switches to vase conformation upon addition of polar solvents such as acetone-d(6) or THF-d(8).

  The present invention relates to a microporous material which is a non-network polymer having a chain comprised of repeating units bonded to each other and each including a first generally planar species and a rigid linker, the linker having a point of contortion such that two adjacent first planar species connected by a rigid linker are held in a non-coplanar orientation, the rigid linker further being such that the polymer chain has a rigid contorted structure, and the polymer being such that said repeating units comprised of the first generally planar species and the rigid linker are bonded predominately to two other such repeating units.
