The invention relates to the technical field of metal organic framework materials, in particular to a polyhydroxy compound and a preparation method and application thereof. The polyhydroxy compound is a 2D[pi]-containing conjugated nitrogen-doped polyhydroxy ligand. By introducing nitrogen atoms and changing the electron density of the ligand, the deprotonation process is relatively easy in the ligand synthesis process, a single crystal can be obtained, and after MOF is synthesized, the MOF is used as a post-modification site and is coordinated with other metals, so that the conductivity is enhanced by increasing the polycyclic aromatic hydrocarbon size of the ligand and enhancing pi-pi conjugation. 本发明涉及金属有机框架材料技术领域，尤其涉及一种多羟基化合物及其制备方法与应用。本发明公开了一种多羟基化合物，该化合物一种含2Dπ共轭氮掺杂多羟基配体，通过引入氮原子，改变配体的电子密度，使在合成配体过程中，脱质子过程比较容易，能得到单晶，并且在合成MOF后，作为后修饰位点，与其他金属进行配位，通过增大配体的多环芳烃尺寸，增强π-π共轭，从而导电性得到增强。
