Recent progress in organic resistance memory with small molecules and inorganic–organic hybrid polymers as active elements

Abstract

The organic resistance memory has attracted a lot of attentions due to its high scalability, flexibility, easy processing, low fabrication cost, etc. Organic small molecules, which own well-defined structures and more accurate experimentsimulation matching, have been widely explored as the active materials for the application in organic resistance memory. In addition, inorganic-organic hybrid polymers have been expected to have charming resistive switching properties because they can potentially combine the advantages of both inorganic materials and organic polymers. This review presents the recent progress of organic resistance memory based on several families of organic small molecules and some typical inorganic-organic hybrid polymers, and the discussion on their structure-property relationships. 53,54 Since then, great progresses have been achieved. The welldefined structures of organic small molecules make them have good batch-to-batch reproducing ability in processing. In addition, the more accurate experiment-simulation matching of organic small molecules is favour for better understanding

Synthesis of new conjugated polymers with coordinated praseodymium complexes for polymer memory devices

“…The Pr-coordinated polymers (PFPh(BipyPr) n ) were prepared by coordination reaction with the Pr-free polymer and Pr triisopropoxide. The feed ratios of Pr complex in the polymers were 4, 6, 8 and 10 mol%, and the corresponding polymers were named PFPh(BipyPr) 4 , PFPh(BipyPr) 6 , PFPh(BipyPr) 8 , PFPh(BipyPr) 10 , respectively. of PFPh(Bipy) n ( Fig.…”

“…In the pioneering studies of polymer resistive memory devices, the doped or blended polymer systems, namely polymer composites, are oen used as the active materials. [6][7][8] Most recently, much attention have been paid to single polymer-based memory materials and devices, which can avoid the problem of phase separation and exhibit promising application for nextgeneration memory devices.…”

Chemistry, synthesis and progress report on biological activities of thiadiazole compounds - a review

“…Approach to practice of medicinal chemistry has developed from an empirical one involving synthesis of new organic compounds based on modification of chemical compounds of known biological activities could be better explored. It is well established that slight alteration in the structure of certain compounds are able to bring drastic changes to yield better drug with less toxicity to the host it observed that chemical modification not only alters physiochemical properties but also pharmacological properties 7 .…”

New acylated 5-thio-beta-D-glucopyranosylimino-disusbstituted 1,3,4-thiadiazoles prepared by cycloaddition of the glycosyl isothiocyanate with the reactive intermediates 1-aza-2-azoniaallene hexachloro antimonates, and have been tested in vitro antiviral activity against HIV-1, HIV-2, human cytomegallovirus (HMCV) [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] .…”

Recent progress on intramolecular charge-transfer compounds as photoelectric active materials

“…Recently, the design and synthesis of novel structures of intramolecular charge-transfer (ICT) compounds have attracted much attention due to their diverse applications in nonlinear optics (NLO) [1], organic photovoltaics [2-8], organic light-emitting diodes (OLEDs) [9], memory devices [10][11][12][13][14], field effect transistors (FETs) [15][16], and so on. ICT compounds normally have coexisted electron donor (D) and electron acceptor (A) moieties, which are connected together through conjugated linkers.…”
