We propose the photopolymerization of lipoic acid (LA) as an novel approach to produce a cross-linked polymeric matrix of lipoic acid monomers (PALA) which helps to control the size of plasmonic gold nanostructures when using 3,3,6,8-tetramethyl-1-tetralone as the photo-initiator for the reduction of Au(III) to Au. A complete characterization of the polymer is included, and the dual behaviour of LA as an in situ stabilizer and reducing agent is investigated. These findings are relevant to the understanding of the photochemical transformation of this biologically relevant compound and would benefit the increasing use of LA and PALA for the synthesis of various nanomaterials.
我们提出利用 lipoic acid (LA) 的光聚合作用来制备 lipoic acid 单体的交联聚合物基质 (PALA)，当使用 3,3,6,8-四甲基-1-四氢萘作为光引发剂还原 Au(III) 为 Au 时，这种方法有助于控制等离子体金纳米结构的大小。我们对聚合物进行了全面的表征，并研究了 LA 作为原位稳定剂和还原剂的双重行为。这些发现对于理解这种具有生物相关性的化合物的光化学转化具有重要意义，并将有益于越来越多地使用 LA 和 PALA 来合成各种纳米材料。
