Abstract
A polymer comprising a fluorescent light-emitting repeating unit comprising a group of formula ED-EA wherein ED is an electron-donating unit; EA is an electron-accepting unit; and a band gap EgCT of a charge-transfer state formed from the electron-donating unit and the electron-accepting unit is smaller than the bandgap of either the electron-accepting unit EgEA or that of the electron-donating unit EgED.
