An acceptor motor-driven electronic donor-acceptor supramolecular scaffold towards imaging-guided tumor therapy.

ABSTRACT: Traditional approaches to accessing near infrared (NIR) photothermal agents mainly focus on synthesis methods. Herein, based on a supramolecular strategy, an electrostatic force-driven electronic donor-acceptor complex is established with 1,4,5,8,9,11-hexaazatriphenylenehexacarbonitrile (HAT-CN) and perylene as the acceptor and donor, respectively. Due to the strong electronic affinity of the acceptor and the opposite electronic properties between them, through-space charge transfer occurs in the assembly, markedly narrowing the energy gap, thereby inducing obvious NIR absorption and benefiting photothermal conversion. More interestingly, the bond stretching vibration is dramatic and sufficient in the acceptor, making it an acceptor motor in the supramolecular complex to further enhance th
