在这里，我们报告的光不稳定的硝基藜芦基表面活性剂，形成不同类型的超分子结构，这取决于烷基链的长度范围从8到12个碳原子的家庭的合成和表征。通过引入可光裂解的α-甲基-邻-硝基藜芦基部分，表面活性剂可以通过光照射以受控的方式降解，沿着它们相应的超分子结构。的两亲性表面活性剂的自组装，其特征在于通过电导测定，以确定形成的超分子结构的临界浓度，透射电子显微镜，以确定的大小和形状的超分子结构，和动态光散射（DLS），以确定在水溶液中的结构的流体动力学直径。使用紫外可见光谱，质谱，和DLS的表面活性剂和超分子结构的光降解进行了确认。该表面活性剂家族可能在药物递送、有机合成和其他应用中具有潜在的用途。
Here we report the synthesis and characterization of a family of photolabile nitroveratryl-based surfactants that form different types of supramolecular structures depending on the alkyl chain lengths ranging from eight to twelve carbon atoms. By incorporating a photocleavable α-methyl-o-nitroveratryl moiety, the surfactants can be degraded, along with their corresponding supramolecular structures, by light irradiation in a controlled manner. The self-assembly of the amphiphilic surfactants was characterized by conductometry to determine the critical concentration for the formation of the supramolecular structures, transmission electron microscopy to determine the size and shape of the supramolecular structures, and dynamic light scattering (DLS) to determine the hydrodynamic diameter of the structures in aqueous solutions. The photodegradation of the surfactants and the supramolecular structures was confirmed using UV-Vis spectroscopy, mass spectrometry, and DLS. This surfactant family could be potentially useful in drug delivery, organic synthesis, and other applications.
