Organic material based on fluorene ring and preparation method and application thereof

The invention discloses a fluorene ring-based organic material and a preparation method and application thereof.The fluorene ring-based carboxyl-containing organic material 9-bis (3-benzoic acid) ethylene-fluorene is synthesized for the first time, and the material has an obvious aggregation-induced emission effect, is weak in luminescence property in a benign solvent and is strong in luminescence property in a poor solvent. The material can be used for detecting aqueous-phase permanganate radicals, meanwhile, due to the fact that the material contains carboxyl, compared with other fluorene compounds, more metal types can be coordinated with oxygen, application is wider, the preparation method is simple, the yield is high, reaction activity is good, and large-scale application and popularization can be achieved. 本发明公开了一种基于芴环的有机材料及其制备方法与应用，本发明首次合成了一种基于芴环且含羧基的有机材料9-二(3-苯甲酸)乙烯-芴，该材料具有明显的聚集诱导发光效应，其在良性溶剂中发光性能弱，在不良溶剂中的发光性能强。该材料能够用于检测水相高锰酸根，同时由于其含羧基，相较于其他芴类化合物可以和氧配位的金属种类更多，应用更广泛，且制备方法简单，产率高，反应活性好，能够大规模应用推广。
