A novel set of multifunctional optically active -conjugated polymers incorporating perylenyl moieties, were designed and synthesized. Chirality transfer and amplification from chiral unit to the main-chain backbone in dilute solution was achieved, which was closely related to the stereocenter in the pendant of a -conjugated polymer. In addition, annealed films of these polymers exhibited near-infrared emission by direct absorption of visible light, resulting from the introduction of a strong fluorophore perylenyl moiety. Such a design strategy opens up new perspectives for the future development of novel optically active materials with near-infrared emission for photonic applications.
