1,1′-Azobis-1,2,3-triazole is a moderately explosive but comparatively stable chemical compound which contains a long continuous chains of nitrogen atoms, with an unbroken chain of eight nitrogen atoms cyclised into two 1,2,3-triazole rings. It is stable up to 194 °C. The compound exhibits cis–trans isomerism at the central azo group: the ''trans'' isomer is more stable and is yellow, while the ''cis'' isomer is less stable and is blue. The two rings are aromatic and form a conjugated system with the azo linkage. This chromophore allows the ''trans'' compound to be isomerised to the ''cis'' when treated with an appropriate wavelength of ultraviolet light. ==Related compounds== In 2011 Azobis(tetrazole) was prepared by Klapötke and Piercey which has a ten-nitrogen chain. The record was later taken by a N11 chain compound synthesized by a group of Chinese researchers. A branched chain N11 system has also been reported as part of an unstable but highly nitrogen rich azidotetrazole derivative with formula C2N14.
