Photo‐Switchable Self‐Assemblies Based on Thymine‐Containing Bolaamphiphiles

Photo‐Switchable Self‐Assemblies Based on Thymine‐Containing Bolaamphiphiles The photoswitching of photosensitive bolaamphiphiles based on thymine was investigated. Topochemical principles were applied to create light‐responsive supra‐amphiphiles by the utilisation of dynamic covalent bonds created by the photo‐dimerisation of a DNA base, thymine. In order to induce the photo‐dimerisation of thymine, two bolaamphiphilic molecules were designed and synthesised to meet the required [2 π+2 π] photo‐cycloaddition conditions. The amphiphiles were synthesised with different spacers and their photo‐reversibility and morphologies were studied by using UV/Vis, NMR and infrared spectroscopy, rheometry, dynamic light scattering and transmission electron microscopy. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png ChemPlusChem Wiley

Abstract

The photoswitching of photosensitive bolaamphiphiles based on thymine was investigated. Topochemical principles were applied to create light‐responsive supra‐amphiphiles by the utilisation of dynamic covalent bonds created by the photo‐dimerisation of a DNA base, thymine. In order to induce the photo‐dimerisation of thymine, two bolaamphiphilic molecules were designed and synthesised to meet the required [2 π+2 π] photo‐cycloaddition conditions. The amphiphiles were synthesised with different spacers and their photo‐reversibility and morphologies were studied by using UV/Vis, NMR and infrared spectroscopy, rheometry, dynamic light scattering and transmission electron microscopy.
