A range of ionic solvatochromic dye (SD) transducers for use in ion-selective emulsified optical sensors are introduced and characterized. They share the same chromophore group, (E)-4-(4-(dimethylamino)styryl)pyridinium, but vary in their lipophilicities by grafted alkyl or ethoxy groups. The calibration curve is found to shift by a total of 2.7 orders of magnitude with the lipophilicity of the SD.
介绍并表征了一系列用于离子选择性乳化光传感器的离子溶剂化变色染料（SD）转换器。它们具有相同的生色团（E）-4-（4-（二甲基氨基）苯乙烯基）吡啶翁，但通过接枝的烷基或乙氧基基团在亲脂性上有所不同。发现 SD 的亲脂性使校准曲线总共移动了 2.7 个数量级。
