title: A photon-working on/off switch for intramolecular donor-acceptor interactions and invisible modulation of the fluorescence.
abstract: An on/off switching for charge-transfer interactions between the side chains of a diarylethene based on photochromic reactions has been proved by the disappearance and appearance of an additional fluorescence band.
