Direct and Divergent Solid-Phase Synthesis of Azobenzene and Spiropyran Derivatives

Here, we report a solid-phase approach to synthesize azobenzene and spiropyran derivatives. The divergent synthesis process requires no purification steps to obtain the desired product with a 28-55% yield, depending on the specific compound. For the spiropyran compounds, solid-phase resin cleavage is performed under mild conditions to minimize spiropyran ring opening. The solid-phase method enables the synthesis of a library of azobenzene and spiropyran derivatives without the need to develop purification strategies for each derivative.

Linear double-branch azobenzene/graphene composite material and preparation method and application thereof

The invention discloses a linear double-branch azobenzene/graphene composite material and a preparation method and application thereof. The linear double-branch azobenzene/graphene composite material is characterized in that linear double-branch azobenzene is grafted to single-layer graphene. The preparation method includes: performing diazotization on 4-aminobenzoic acid, allowing the processed 4-aminobenzoic acid to have reaction with aniline to generate azobenzene molecules, performing amino protection on the azobenzene molecules, and performing amidation on the azobenzene molecules and para amino azobenzene-4-sulfonic acid to obtain amino protected double-branch azobenzene; removing amino protection, and hybridizing and compositing the prepared double-branch azobenzene and reduced graphene oxide through diazotization to obtain the linear double-branch azobenzene/graphene composite material. The prepared double-branch azobenzene/graphene hybrid material has the advantages that the energy value and half-life period of the material are greatly improved as compared with those of azobenzene small molecules, the energy density of the material is stabilized at 158Wh/Kg, the half-life period of the material is prolonged to above 1000 hours, and the material is good in thermal stability and circulating performance and beneficial to solar heat storage.

Fluorescent composite hydrogels of metal-organic frameworks and functionalized graphene oxide

GO MOFs! Azobenzoic acid functionalized graphene (A-GO) can act as a structure-directing template that influences hydrogel formation together with metal-organic frameworks (MOFs). Zn2+ MOFs of pyridine derivatives work as framework linkers between the A-GO sheets (MOF-A-GO, see figure). MOF-A-GO exhibits a strong fluorescence enhancement upon gel formation. In addition, MOF-A-GO selectively recognizes trinitrotoluene. Copyright
