Overview | Product Information | MSDS | Related Products

[1,1'-Biphenyl]-2,2'-dicarbonitrile (CAS number 4341-02-0) is a biphenyl building block with two nitrile groups at its bay positions. With the two nitriles, [1,1'-biphenyl]-2,2'-dicarbonitrile undergoes trimerization reactions for the preparation of triazine-based COFs. [1,1'-Biphenyl]-2,2'-dicarbonitrile is a key component for the synthesis of azepiphthalocyanine, a π-conjugated bowl-shaped molecule. The resulting azepiphthalocyanine incorporates a seven-membered ring in its structure, attributing to the curved surfaces.

A thermally activated delayed fluorescent (TADF) emitter consists of a [1,1'-biphenyl]-2,2'-dicarbonitrile core and carbazoles. This narrow band TADF emitter exhibits deep blue fluorescence with a full width at half maximum of 48 nm and a quantum efficiency of 14%.
