Patent ID: 8901312

Claim:
A cyclic compound comprising a cyclic skeleton of an 8-membered ring and two triazole rings sharing carbon-carbon double bond sites with the cyclic skeleton, wherein the triazole rings are formed by adding and ligating an azide compound having an azido group to each of the two carbon-carbon triple bond sites on the cyclic skeleton in a cyclic diyne compound by a double click reaction; and the cyclic compound further comprises two benzene rings sharing the carbon-carbon double bond sites with the cyclic skeleton, wherein the cyclic compound is represented by formula (1) or (2) below: (in formula (1), each R independently represents hydrogen or a hydrocarbon group, and each n independently represents an integer of 0 to 4), and, (in formula (2), each R independently represents hydrogen or a hydrocarbon group, and each n independently represents an integer of 0 to 4).
