A widely used electron deficient anthraquinone building block

For the synthesis of semiconducting small molecules or polymers in application of fluorophores, photocatalyst, OLEDs and organic solar cells

2,6-Dibromoanthraquinone (CAS number 633-70-5) has an electron deficient structure of anthracene-9,10-dione with bromo substituents at 2,6-position of the anthraquinone ring. Both the bromo and 9,10-dione functional groups enable the anthracene core to extend its conjugation for the preparation of more complex structures, i.e., semiconducting small molecules or polymers in application of fluorophores, photocatalyst, OLEDs and organic solar cells.

Containing anthraquinone center prepared by cross-coupling reaction between 2,6-dibromoanthraquinone and 1,1,2,2-tetrakis(4-ethynylphenyl)ethene, conjugated organic polymer (AQTEE-COP) demonstrated efficient photocatalytic H2O2 production with an initial rate of 3204 μmol g-1 h-1 under visible light (λ ≥ 400 nm) irradiation without any additional photosensitizers, organic scavengers, or co-catalysts.

Developed for bioimaging in the NIR-II window, novel donor–acceptor–donor type second near-infrared AIE fluorophores AQMN, based on strong electron-acceptor 2,2′-(anthracene-9,10-diylidene) dimalononitrile which was also derived from 2,6-dibromoanthraquinone, exhibit good photostability and can be used in mouse ear vessel imaging with high resolution (FWHM = 93.4 μm/SBR = 1.5) after capsuling in nanoparticles with good biocompatibility.
