Method for preparing coronene compound from non-cyclic olefin
-
Paragraph 0077-0085, (2020/10/30)
The invention relates to a method for preparing a coronene compound from non-cyclic olefin. The method is characterized by comprising the following steps of: putting a reaction raw material into a reactor, and carrying out contact reaction with a catalyst containing an activated silicon-aluminum molecular sieve to obtain the coronene compound; wherein the reaction raw material comprises non-cyclicolefin. The method is mild in preparation condition, easy to operate and simple in process; the adopted raw material is low in cost and easy to obtain, therefore the method is suitable for large-scale production.

Paragraph 0356; 0359; 0360; 0363; 0364, (2019/02/13)
An organic compound, a three-dimensional organic structure formed by using the organic compound, a separation sieve and an optical layer having the organic structure, and an optical device having the optical layer as an optical amplification layer are provided. The organic structure includes a plurality of organic molecules self-assembled by non-covalent bonding. Each of the unit organic molecules has an aromatic ring, a first pair of substituents being connected to immediately adjacent positions of substitutable positions of the aromatic ring, and a second pair of substituents being connected to immediately adjacent positions of remaining substitutable positions of the aromatic ring. The unit organic molecules are self-assembled by van der Waals interaction, London dispersion interaction or hydrogen bonding between the first and the second pairs of the substituents and by pi-pi interactions between the aromatic rings.
1, 5, 9-trisubstituted coronene compound and synthesis method thereof

Paragraph 0058; 0059; 0062; 0063, (2017/05/02)
The present invention relates to a 1, 5, 9-trisubstituted coronene compound and a synthesis method thereof. The structural formula of the compound is shown in img file = 'dest _ path _ image 001. TIF 'wi = '109 'he = '108', wherein R represents H, C1-C18 alkyl, phenyl, 4-methylphenyl, 4-methoxy phenyl, benzyl, cyclohexyl, 4-trifluoromethylphenyl, thiophene, furan and the like. According to the technical scheme of the invention, the easily prepared 1, 5, 9-triamido triphenylene is subjected to diazotization and halogenation reaction to obtain the tri-halogenated triphenylene. After that, the tri-halogenated triphenylene is subjected to Sonogashira reaction with various alkynes to generate atriyne-triphenylene compounds. Finally, through the metal-catalyzed reaction and the cyclization reaction under the effect of an organic base, various 1, 5, 9-trisubstituted coronene compounds, novel in structure, can be obtained. According to the technical scheme of the invention, raw materials are easy for mass preparation. Meanwhile, the synthesis step is relatively short and the operation is convenient. The obtained trisubstituted coronene compound is good in thermal stability and chemical stability, and the trisubstituted coronene emits the relatively strong fluorescence within the range of 420-550 nm according to the fluorescence emission spectrum of the trisubstituted coronene compound. Therefore, the trisubstituted coronene is an excellent fluorescent material for preparing UV ultraviolet charge-coupled devices (UV-CCD) and organic light-emitting diodes (OLEDs), and has a wide application prospect in the field of electronic materials.
