Amphiphilic molecule containing o-nitrobenzyl ester photo-degradation group

The invention discloses a novel photodegradable amphiphilic molecule and a synthetic method thereof, and belongs to the field of surfactants. The synthetic method comprises the five steps that (1) diethylenetriamine pentaacetic acid is taken as a raw material, acetic anhydride is taken as a dehydrating agent, and pyridine catalytic dehydration is performed to produce diethylenetriamine pentaaceticdianhydride; (2) methylene of 6-nitropiperonal is removed under the action of aluminum chloride and hydrobromic acid; (3) 4,5-dihydroxy-2-nitrobenzaldehyde and bromoalkane are subjected to an etherification reaction under an alkaline condition; (4) the 4,5-dihydroxy-2-nitrobenzaldehyde is reduced to 4,5-dihydroxy-2-nitrobenzyl alcohol under the action of a reducing agent; (5) the 4,5-dihydroxy-2-nitrobenzyl alcohol and the excess diethylenetriamine pentaacetic dianhydride are subjected to an esterification reaction to obtain the o-nitrobenzyl ester amphiphilic molecule. The novel photodegradable amphiphilic molecule and the synthetic method thereof have the advantages that the reaction condition of an o-nitrobenzyl alcohol derivative and the diethylenetriamine pentaacetic dianhydride is mild, the excess diethylenetriamine pentaacetic dianhydride is used for reducing the occurrence of side reactions, and the amphiphilic molecule has good ultraviolet photodegradability.

Mussel-inspired healing of a strong and stiff polymer

Self-healability will greatly improve the reliability, service life and maintenance of synthetic materials. However, it remains a big challenge to realize the self-healing of a strong and stiff polymer due to its poor molecular mobility. Inspired by the h

An approach to the asymmetric synthesis of 18F-labeled analog of l-threo-3,4-dihydroxyphenylserine (6-l-threo-[18F]FDOPS) - A new radiotracer for visualization of norepinephrine transporters by positron emission tomography

An asymmetric synthesis method has been suggested as a feasible approach for the preparation of fluorine-18-labeled (T 1/2 110 min) analog of l-threo-3,4-dihydroxyphenylserine, i.e., 6-l-threo-[18F]FDOPS ((2S,3R)-2-amino-3-(2-[1
