  Synthesis, characterization, and solvent-independent photochromism of spironaphthooxazine dimers

  摘要：

  Specifically angled, conjugated spiroindolinonaphthooxazine dimers (SNOD) have been synthesized. The photochromic reactions of two types of SNOD were studied under continuous UV irradiation in solvents of different polarity. Comparison of these results with the single unit provides the examination of the specific effect of substituents on their photochromic properties and relaxation kinetics. The photomerocyanine isomers showed positive solvatochromism, supporting the premise for a less polar quinoidal structure. The thermal closing rate at 25 degrees C ranged from 0.2 to 1.6 s(-1) depending on the compound and solvent. Photochromism of these new compounds showed little dependency on solvent polarity and stable cyclability. (C) 2011 Elsevier B.V. All rights reserved.

• Designing dendritic frameworks using versatile building blocks suitable for CuI-catalyzed alkyne azide ‘click’ chemistry
  作者：Rami Hourani、Anjali Sharma、Ashok Kakkar

  DOI：10.1016/j.tetlet.2010.05.061

  日期：2010.7

  Synthesis of molecular building blocks that incorporate azide and alkyne-terminated functionalities suitable for Cu-I-catalyzed cycloaddition between alkynes and azides is reported. Their utility in constructing dendritic frameworks with 4, 6, or 12 peripheral acetylene groups using either the convergent or divergent methodology, and their functionalization with desirable end groups are demonstrated.
