“…This suggests that the resistance switching would not be dominated by filament conduction since there is no effective pathway for metal penetration in the uniform and crack-free active layer. [15][16][17] To elucidate the conduction mechanism of resistive switching in the memory device, the optimized molecular geometry and electronic properƟes are depicted in Figs. 3 and S2 (ESI †) through density functional theory simulation method.…”

Solution processable star-shaped donor-acceptor (D-A) conjugated molecules (TPA-T-NI and TPA-3T-NI) with an electron-donating triphenylamine (TPA) core, three thienylene or terthienylene spacers, and three 1.8-naphthalimide (NI) electron-withdrawing end-groups are explored for the first time as charge storage materials for resistor-type memory devices owing to the efficient electric charge transfer and trapping.

Three two-dimensional like conjugated copolymers PFSDCN, PFSDTA and PFSDCNIO, which consist of alternating fluorene and triphenylamine main chain, and different pendant acceptor groups (malononitrile, 1,3-diethtyl-2-thiobarbituric acid and 2-(1,2-dihydro-1-oxoinden-3-ylidene)malononitrile) with thiophene as -bridge, have been designed, synthesized and characterized. The structure-property relationships of the two-dimensional like conjugated copolymers were systematically investigated. The absorption spectra, band gaps, and energy levels of the polymers were effectively tuned by simply attaching different acceptor groups. As the electron-withdrawing ability of the acceptors increased, the band gaps of the polymers were narrowed from 2.05 to 1.61 eV; meanwhile, the LUMO energy levels of the polymers decreased from 3.27 to 3.75 eV, whereas their relatively deep HOMO energy levels of ~5.35 eV were preserved. BHJ solar cells were fabricated and characterized by using the three polymers as donor materials and the highest power conversion efficiency of 2.87% was achieved for the device based on PFSDTA:(6,6)-phenyl-C 71 -butyric acid methyl ester blend. conjugated polymers, two-dimensional like polymers, band gaps, bulk-heterojunction solar cells

A thin conductive polymer recording medium with angstrom-scale surface roughness has been formed on template-stripped gold (TSG) surface by surface-graft polymerization for scanning multiprobe data storage. A gold film is deposited on a mica plate, which is bonded onto the silicon substrate with a gold film using gold-gold direct bonding technique. By removing the mica plate, gold surface with the angstrom-scale surface roughness is formed. A conductive polymer film as a recording medium is deposited on the TSG surface by the surface-graft polymerization. As a result, the polymer film with small roughness is obtained. Thus, the use of the TSG surface is efficient way to form the flat conductive polymer film. Finally, reversible electrical modification on the polymer film is demonstrated using atomic force microscopy. These results show the possibility that this formation method of the conductive polymer film provides rewritable recording media with small roughness for scanning multiprobe high-density data storage.
