Shape?Memory Metallopolymers Based on Two Orthogonal Metal–Ligand Interactions
نویسندگان
چکیده
A new shape-memory polymer is presented, in which both the stable phase as well switching unit consist of two different metal complexes. Suitable ions, simultaneously form labile complexes with histidine and ones terpyridine ligands, are identified via isothermal titration calorimetry (ITC) measurements. Different copolymers synthesized, contain butyl methacrylate main monomer metal-binding ligands side chains. Zn(TFMS)2 NiCl2 utilized for dual crosslinking, resulting formation metallopolymer networks. The temperature can simply be tuned by changing composition choice ion. Strain fixity rates (about 99%) very high strain recovery (up to 95%) achieved mechanism revealed using techniques such Raman spectroscopy.

Conducting metallopolymers based on azaferrocene.
A series of 2,5-thiophene-substituted 1',2',3',4',5'-pentamethylazaferrocene complexes were synthesized and electropolymerized to produce polymers with fully pi-conjugated backbones. The length and hence oxidation potential of the conjugated linker (the thiophene fragments) between the metal centers were varied to understand the influence of the metal-metal interactions on the overall electroac...
متن کاملA four-component organogel based on orthogonal chemical interactions.
A thermoresponsive organogel was obtained by orthogonal assembly of four compounds using dynamic covalent boronate ester and imine bonds, as well as dative boron-nitrogen bonds. It is shown that the gel state can be disrupted or reinforced by chemicals which undergo exchange reactions with the gel components.
متن کاملQuantum Private Query Protocol Based on Two Non-Orthogonal States
We propose a loss tolerant quantum private query (QPQ) protocol based on two non-orthogonal states and unambiguous state discrimination (USD) measurement. By analyzing a two-point attack by a third party, we find that our protocol has a stronger ability to resist external attacks than G-protocol and Y-protocol. Our protocol requires a smaller number of compressions than that in G-protocol (Gao ...
متن کاملGeographic Information Retrieval based on Two Orthogonal Criteria
A Geographic Information Retrieval (GIR) model is defined and the architecture of a GIR system, named Geo-Finder, is described. The GIR system is constituted by two main modules. The geo-indexing module applies bipolar criteria to automatically identify the geo-reference focus (footprint) of textual documents. The geo-retrieval module applies a context dependent matching function to evaluate qu...
متن کاملOn Two Dimensional Orthogonal Knapsack Problem
In this paper, we study the following knapsack problem: Given a list of squares with profits, we are requested to pack a sublist of them into a rectangular bin (not a unit square bin) to make profits in the bin as large as possible. We first observe there is a Polynomial Time Approximation Scheme (PTAS) for the problem of packing weighted squares into rectangular bins with large resources, then...
