Synthesis and optical and electrochemical memory properties of fluorene–triphenylamine alternating copolymer

Abstract

A fluorene–triphenylamine copolymer (PF–TPA) was designed and synthesized under Suzuki coupling reaction conditions in this work. It exhibited a typical electrical conductance switching behavior and non-volatile flash memory effects.

Flash memory devices and bistable nonvolatile resistance switching properties based on PFO doping with ZnO

“…When the negative voltage is scanned, ITO serves as anode (À4.80 eV) and an Al as cathode (À4.27 eV). 29 As shown in Fig. 11(a), the energy barrier between the cathode and the LUMO of PFO is 1.25 eV, much greater than the minimum .…”

Preparation and flash memory performance based on fluorene–triphenylamine copolymer (PF–TPA)/MWCNTs

“…The resulting heat and this repulsive coulombic interaction cause the lament to rupture and make the device make the device revert back to the OFF state. 37 In view of the limited charge conduction capacity of polymers, carbon nanotubes are more likely as electron trapping center, introduced into the polymer active lms to enhance charge injection and trapping. 25,36 As shown in Fig.…”

Regulating the electrical resistive switching behaviors of polyimides through different steric hindrance substituents on 2,7-position of tetraphenyl fluorene diamines moieties

“…For the past few years, with the birth of new memory device materials, the traditional inorganic silicon-based materials can no longer meet the future development needs, highperformance polymer resistance memory devices are more and more attention. [1][2][3][4][5][6][7][8][9] Among the polymers, aromatic polyimide (PI) is considered to be a promising candidate material owing to its solution processability, low cost, good scalability, excellent thermal stability, and chemical resistance. Therefore, a lot of research has focused on synthesizing PI molecules and exploring the relationship between molecular structure and memory behavior.…”
