对位取代的水杨基二醛是多孔有机笼、荧光染料、螺苯并吡喃、高氧杂杯芳烃、双核金属配合物、大环化合物和穴状配体的通用分子构建块。迄今为止，还没有报道用于合成对位芳基取代的水杨基二醛的方法，这将拓宽上述主题的范围，特别是在传感器和染料领域，因为芳香族π系统可以被扩大，并且吸收或荧光事件可以通过各种取代基进行微调。本文报道了两种同时具有吸电子和供电子芳香单元的对芳基取代水杨醛的合成路线。
para-Substituted salicyldialdehydes are versatile molecular building blocks for porous organic cages, fluorescent dyes, spirobenzopyrans, homooxacalixarenes, dinuclear metal complexes, macrocycles, and cryptands. To date, no procedures for the synthesis of para-aryl-substituted salicyldialdehydes have been reported, which would broaden the scope of the above-mentioned topics, especially in the field of sensors and dyes, because the aromatic π systems can be enlarged and absorption or fluorescent events can be fine-tuned by various substituents. Herein, two synthetic routes to para-aryl-substituted salicyldialdehydes with both electron-withdrawing and -donating aromatic units are reported.
