Efficient synthesis of 1,3-dibromopyrene from 1-methoxypyrene was achieved with an overall yield of 71 %. This compound was successfully converted into 13OPA, a long-axially symmetricpyrene dye with electron donor–acceptor groups, which exhibits photophysical properties markedly distinct from those of its point-symmetric and short-axially symmetric isomers. These findings are valuable for the development
