  Synthesis of calixarene-based ketocyanine fluorophores

  摘要：

  Cup-shaped calix[4]arenes bearing one or two ketocyanine fluorophore fragments at the wide rim of the macrocycle are synthesized by condensation of formyl calix[4]arenes with arylmethylene(hetarylmethylene)cyclopentanones in the presence of the ionic liquid, dimethylammonium dimethylcarbamate (DIMCARB) and characterized using UV-vis and fluorescence spectroscopy. Strong positive solvatofluorochromism for the calixarene ketocyanines is observed. (C) 2011 Elsevier Ltd. All rights reserved.

  摘要：

  The complex formation of 2,5-bis[4-(1,7,10,13-tetraoxa-4-azacyctopentadec-4-yl)benzyl-idene]cyclopentanone and several model compounds, prospective metal-sensitive fluorescent probes, with Mg2+, Ca2+, and Ba2+ ions in acetonitrile was studied. The azacrown derivatives of dibenzylidenecyclopentanone have two complex formation centers, azacrown cycle and carbonyl group. The sequence of binding to these sites is different for different ions, The efficient ejection of the Ca2+ and Ba2+ ions from their complexes with azacoronands was observed in the excited state, whereas in the case of the Mg2+ ion, this process occurred only partially.

  [EN] Disclosed is an ink, which has a viscosity and a volumetric shrinkage, controlled to 20~80 cP and 10~30%, respectively, by controlling an amount of each of : (a) a first monomer having a viscosity of 7~l,600 cP and having one or two polymerizable functional groups; and (b) a second monomer having a viscosity of 30-20,000 cP and having at least three polymerizable functional groups, in the presence of 0~20 wt% of a solvent, and which can form a convex portion due to its surface tension controlled to 20~40 mN/m, so as to compensate for its volumetric shrinkage, wherein the viscosity and the surface tension are measured at 25°C. A substrate, which is patterned or information-recorded with the ink, and a display device having the substrate are also disclosed.
  [FR] L'invention concerne une encre, présentant une viscosité et une réduction volumétrique de 20~80 cP et de 10~30 %, respectivement, par réglage de la quantité (a) d'un premier monomère présentant une viscosité de 7~1 600 cP et contenant un ou plusieurs groupes fonctionnels polymérisables, et (b) d'un second monomère présentant une viscosité de 30-20 000 cP et contenant au moins trois groupes fonctionnels polymérisables, en présence de 0~20 % en poids d'un solvant, et pouvant former une partie convexe grâce à sa tension de surface réglée sur 20~40 mN/m, de manière à compenser sa réduction volumétrique, la viscosité et la tension de surface étant mesurées à 25 °C. L'invention concerne également un substrat présentant un motif ou des informations enregistrées à l'aide de l'encre, et un dispositif d'affichage formé dudit substrat.
