Abstract
Provided are any one of the following fluorescent compounds and a fluorescent labeled biological substance having this fluorescent compound. However, in a case where the ring β1 and the ring β2 are a 6-membered ring, and L1 and L2 are an arylene group, R5 is not an aryl group substituted with a linear alkyl group having 18 or more carbon atoms. In addition to the regulation of the ring β1, the ring β2, L1, and L2, in a case where R5 has a substituent having a dipyrromethene boron complex structure, the dipyrromethene boron complex structure has a structure in which a dipyrromethene skeleton is coordinately bonded to a boron atom in the tridentate or tetradentate coordination.
