As promising nonlinear dynamic electronic devices with widespread potential applications in computer data storage and neuromorphic implementations, memristors have attracted tremendous attention in both materials science and condensed-matter physics. In this work, self-rectified memristive behavior was for the first time observed in a highly soluble metal-free all-organic material containing electron-rich fluorene and dithieno[3,2-b:2′,3′-d]pyrrole moieties in the oligomer mainchain as conjugated channels for charge carriers and electron-poor 9,9-bis(3,4-bis(3,4-dicyanophenoxy)phenyl side chains in the C-9 position of the fluorene units (hereafter denoted as "PFD-8CN"). Electrical conductance of PFD-8CN can be switched between two states with a rectification ratio of ～10, incrementally and repeatedly. Non-linear transmission characteristics of a biological synapse are also realized through consecutive multilevel conductance switchings. The novel electrical response of the device arises from electric field-induced charge transfer interactions in the donor-acceptor structured oligomer. The development of the organic memristor may offer new opportunities for the construction of molecular electronics that can greatly enhance the performance of modern computer systems.

A highly soluble polyfluorene-based copolymer containing electron-rich triphenylamine (TPA) and electron-poor 9,9-bis(3,4-bis(3,4-dicyanophenoxy)phenyl side chains in the C-9 position of the fluorene unit was synthesized under Yamamoto conditions. By appl
