title: Generation of a triplet diradical from a donor-acceptor cross conjugate upon acid-induced electron transfer.
abstract: Enhancement of the electron acceptor ability of a para-quinodiimine unit by double protonation leads to the proton-induced intramolecular electron transfer from the donor unit to the cross-conjugated acceptor, giving rise to ground state triplet diradical reversibly.
