Embodiment 1

[0028] In a 250mL four-necked flask equipped with a thermometer, a reflux condenser and a mechanical stirrer, add 30.5g (0.167mol) of 4-chlorophthalic anhydride and succinic acid (1:1 in molar ratio), and heat up to 210°C. Start stirring, add potassium acetate (the molar ratio of potassium acetate to 4-chlorophthalic anhydride is 0.2:1), and react at 210°C for 2.5 hours. Then lower the temperature to 100°C, add hot water and introduce steam. Until the reaction product forms crushed particles, filter, wash the product with hot water, dry, and boil with ethanol to remove resinous impurities. Filter again, wash with ethanol until the eluate is colorless, and dry to obtain 18.3 g of reddish yellow powder, which is an intermediate for synthesizing 4-chloroindene isolactone.

[0031] In a 250mL four-neck flask equipped with a thermometer, reflux condenser and mechanical stirring, add 30.5g (0.167mol) of 4-chlorophthalic anhydride and succinic acid (molar ratio: 1:1.5), and heat up to 210°C . Start stirring, add potassium acetate (the molar ratio of 4-chlorophthalic anhydride to potassium acetate is 1:0.3), and react at 210°C for 2.5 hours. Then lower the temperature to 100°C, add hot water and introduce steam. Until the reaction product forms crushed particles, filter, wash the product with hot water, dry, and boil with ethanol to remove resinous impurities. Filter again, wash with ethanol until the eluate is colorless, and dry to obtain 15.6 g of reddish-yellow powder, which is an intermediate for the synthesis of 4-chloroindene isolactone.

[0034]In a 250mL four-neck flask equipped with a thermometer, reflux condenser and mechanical stirring, add 30.5g (0.167mol) of 4-chlorophthalic anhydride and succinic acid (molar ratio: 1:2), and heat up to 210°C . Start stirring, add potassium acetate (the molar ratio of 4-chlorophthalic anhydride to potassium acetate is 1:0.3), and react at 210°C for 2.5 hours. Then lower the temperature to 100°C, add hot water and introduce steam. Until the reaction product forms crushed particles, filter, wash the product with hot water, dry, and boil with ethanol to remove resinous impurities.

Abstract

The invention discloses a solid magnetic and fluorescent difunctional organic compound of 4-chlorobiindenylisolactone and a synthesis method thereof. The method synthesizes the 4-chlorobiindenylisolactone of the structural formula below by using tetrachlorophthalic anhydride and succinic acid as raw materials. The synthesis method comprises the following steps that: the tetrachlorophthalic anhydride and the succinic acid are mixed to form an intermediate for synthesizing the 4-chlorobiindenylisolactone; and then the intermediate is used to synthesize the 4-chlorobiindenylisolactone in the presence of a sodium methoxide catalyst. The 4-chlorobiindenylisolactone provided by the invention is a difunctional organic compound having fluorescent and magnetic functions and can be used in the fields of fluorescent marks and fluorescent recognition as well as the fields of new-generation high storage capacity information materials, insulating materials, light bandwidth microwave absorbent, magnetic sensors, low-loss high-frequency microwave communication apparatuses, magnetically sealing apparatuses, magnetic shielding, magnetic separation and microwave communication.

Description

【Technical field】: [0001] The invention belongs to the technical field of organic material synthesis, in particular to an organic compound with dual functions of fluorescence and magnetism and a synthesis method thereof. 【Background technique】: [0002] Organic magnets are a multidisciplinary interdisciplinary frontier subject, which involves organic, inorganic, organometallic, polymer, physical chemistry, condensed matter physics, etc. The design, synthesis and application of [1] Molecular solid (Molecular solid), an emerging multidisciplinary research field. For a long time, people thought that only inorganic substances had the above properties, while organic substances were considered to be diamagnetic substances or electrical insulators. Until recently, it has been proved theoretically and experimentally that certain special organic materials can exhibit magnetism or transform into conductors or even superconductors after being doped or combined with other organic or i...
