Embodiment Construction

[0035] The preparation and properties of the copolymerized pillar 5 arene and its gel of the present invention will be further illustrated below through specific examples.

[0036] 1. Synthesis of copolymerized pillar 5 aromatics (compound DCP5-12)

[0037] Synthesis of intermediates: hydroquinone (4.4g, 40mmol), potassium carbonate (40g, 280mmol), potassium iodide (4g, 24mmol), bromododecane (10.96g, 44mmol) and acetone (300.0mL) were added Put it into a 500mL round-bottom flask, stir for 3 days (72h), the solid precipitates out, and the intermediate is obtained. 1H NMR (400MHz, CDCl 3 , 275 K) δ (ppm): 6.81(d, 4H), 3.91-3.87 (t, 4H), 1.74 (t, 4H), 1.43 (t, 4H), 1.26 (t, 32H), 0.88-0.86 ( t, 6H). The yield was 80%.

[0038] The synthesis of DCP5-12: the intermediate (2.23g, 5mmol), p-xylylene dimethyl ether (2.76g, 20mmol) was added to dissolve in 80mL 1,2-dichloroethane; then paraformaldehyde (0.75g, 25mmol), boron trifluoride diethyl ether (3.2mL, 25mmol) were added to...

Abstract

The invention discloses a preparation method of supramolecular copolymerization column five-aromatic hydrocarbon gel with ductility and stretchability. The preparation method comprises that a long alkyl chain is introduced to a column aromatic hydrocarbon structure of the copolymerization column five aromatic hydrocarbons as gelators and penetrates into the cavity of the column aromatic hydrocarbon structure under the action of C-H. pi driving power so that the supramolecular copolymerization column five-aromatic hydrocarbon gel is formed by self-assembling. The gel can be reversely transformed between gel and a solution by heating and cooling. The gel has good ductility, stretchability and transparency, good resistance to inorganic acid and alkali, and good latent uses in acid- and alkali-resistant materials.

Description

technical field [0001] The invention relates to a supramolecular gel, in particular to the preparation of a supramolecular copolymerized column 5 arene gel with condensed state fluorescence, and belongs to the field of organic gels. Background technique [0002] Organogel is a low molecular weight organic compound (gel molecule) in an organic solvent through hydrogen bonding, van der Waals force, π-π Supramolecular (soft) materials formed by self-assembly of weak interactions between molecules such as stacking. This material has the unique advantages of solid materials and liquid materials at the same time: the gel molecules maintain their own chemical properties and can carry out some reactions in the solution. At the same time, the gel material has the stability similar to solids, such as easy storage, etc. Advantages, therefore, have broad applications in the field of supramolecular soft materials. [0003] Pillararenes as a new class of macrocyclic molecular hosts have...
