Because volatile compounds evaporate from surfaces that are usually exposed to daylight, photoresponsive delivery systems are particularly suitable to control their release. In the present study, we investigated 4,4-diphenyl-4H-benzo[d][1,3]dioxins as profragrances for the light-induced delivery of aldehydes in functional perfumery. The efficiency of fragrance release was investigated on cotton after
由于挥发性化合物会从通常暴露在日光下的表面蒸发,因此光响应性输送系统特别适合于控制其释放。在本研究中,我们研究了4,4-二苯基-4H-苯并[d] [1,3]二恶英作为在功能性香料中光诱导醛的传递的香精。研究了从织物柔软配方直接和间接表面沉积后,棉花上香精释放的效率与香气结构的取代方式之间的关系。棉花表面上方的动态顶空分析表明,与目标表面的沉积量相比,香气的结构对香气释放的影响要大得多。尽管观察到的溶液中光解的一些趋势也适用于棉花反应,但通常无法根据其溶液性质预测结构上不同的前体在表面上的光化学行为。本系统在干燥表面上执行的事实使其成为用于其他类型的生物活性挥发性化合物(例如信息素或农用化学品)的有趣的光触发传递媒介。
