Embodiment Construction

[0012] The present invention will be further described in detail below in combination with specific embodiments.

[0013] A kind of novel fluorescent macrocyclic molecular compound containing imidazolium salt proposed according to the present invention, its preparation method is:

[0014] Add 10 mL of acetone, 5 mmol of carbazole, 7.5 mmol of NaOH, 0.008 g of TBAB to the reaction flask, reflux for 2 hours, then add 5 mmol of hexyl bromide, stir, reflux for 24 hours, cool to room temperature, and concentrate the obtained reaction solution in vacuo Finally, add a large amount of water, filter, and recrystallize from ethanol to obtain N-hexylcarbazole as a white powder with a yield of 90%;

[0015] Under nitrogen protection, add 5 mmol N-hexylcarbazole, 20 mmol paraformaldehyde, 0.5 mmol ZnCl to 20 mL of anhydrous THF 2 , stirred, added dropwise HBr solution, reacted at 60°C for 24h, and obtained 3,6-dibromomethyl-9-hexylcarbazole after post-treatment, a light yellow solid with ...

Abstract

The invention belongs to the super-molecule chemistry field and specifically relates to a novel carbazole-based cyclophane. The structure formula of the novel carbazole-based cyclophane is shown in the specification, wherein n is greater than 0. The novel carbazole-based cyclophane is good in fluorescence and wide in application range, and can be used for constructing super-molecule sensors in the molecule identification field; and meanwhile, the cyclophane containing long-chain alkyl in the novel carbazole-based cyclophane can be taken as quaternary ammonium salt type surfactants and has potential application prospect in the field of surfactants.

Description

technical field [0001] The invention belongs to the field of supramolecular chemistry, and in particular relates to a novel carbazole-based cyclopan. Background technique [0002] Carbazole and its derivatives have good optical and thermal properties because of their large π-electron conjugated system, rigid planar structure, and strong intramolecular electron transfer properties, and are a superior hole-transporting material. At present, most of the research on carbazole and its derivatives is focused on the direction of optoelectronic materials. The 3,6-position substituted carbazole and 2,7-position substituted carbazole and their derivatives are often used in In the production of OLED materials, carbazole-based supramolecular chemistry has been less studied. [0003] The research field of supramolecular chemistry mainly involves molecular recognition, molecular catalysis, molecular self-assembly, supramolecular drugs, etc. Among them, molecular recognition is the proce...
