N，N '-二环己基-N-（6'-甲氧基蒽基-2-羰基）脲（1a）具有较强的溶致变色性，并具有荧光性质。1a的最大发射峰与溶剂的阴离子稳定性质有很好的相关性。该特征允许检测具有高受体数的分析物，例如醇和羧酸，以及检测与酰胺基氢原子形成强氢键的分析物，例如氟离子。
N,N‘-Dicyclohexyl-N-(6‘-methoxyanthryl-2-carbonyl)urea (1a) exhibits a strong solvatochromism with respect to its fluorescence properties. The emission maxima of1acorrelate well with the anion-stabilizing properties of the solvent. This feature allows the detection of analytes with high acceptor numbers, such as alcohols and carboxylic acids, and the detection of analytes such as fluoride ions which form strong hydrogen bonds with the amido hydrogen atom.
