A new series of N-PSe resonance-based fluorescent molecules were developed and used for the detection of hypochlorous acid (HClO) with rapid response and high selectivity. These Se-containing molecules can selectively detect trace amounts of HClO in nM, showing significantly strengthened fluorescence due to the enhanced resonance variation with an increased distance between the fluorophore and Se. The design of N-PSe resonance molecules in donor-resonance-acceptor (D-r-A) architectures could be an important way to develop high-performance turn-on fluorescent probes for HClO detection.

Paragraph 0085; 0086, (2017/09/12)
The invention discloses a selenium atom-containing fluorescence probe, and a preparation method and an application thereof, and belongs to the field of functional materials. The structural general formula of above material is represented by formula (I) shown in the description; and in the formula (I), Ar is a carbazolyl or diphenylamino group, and Ph is a phenyl group. The preparation method of the material concretely comprises the following steps: reacting carbazole/diphenylamine with dichlorophenylphosphine/diphenylchlorophosphine to form a derivative containing an N-P structure, and carrying out chemical modification to introduce selenium atoms in order to form the selenium atom-containing fluorescence probe. The method has the advantages of simple synthesis steps, mild conditions, low production cost and high thermal stability. Se=O double bonds are formed through the reaction of the selenium atoms and hypochlorite radicals in order to generate fluorescence change. The selenium atom-containing fluorescence probe has the advantages of high sensitivity and high selectivity.

Increased resonance: The selective tuning of the optoelectronic properties of organic semiconductors is possible by enantiotropic resonance variation. Using resonance forms of N+i￡P-O- in a series of arylamine-phosphine oxide hybrids afforded low-voltage-driven phosphorescent OLEDs with outstanding performances. Copyright
