Synthesis and properties of template-promoted switchable dithienylethene-based macrocycles
摘要:
Three switchable macrocycles based on photochromic dithienylethene were synthesized under the template of dibenzylammonium hexafluorophosphate. Their structure were well-confirmed by NMR, ESI-MS and X-ray diffraction. Their photochromism indicated that they showed good reversibility in solution. Additionally, the theoretical calculation suggested that photoirradiation can change the cavity of macrocycles. (C) 2013 Jun Yin. Published by Elsevier B.V. on behalf of Chinese Chemical Society.
