Realizing shape and size control for the synthesis of coordination polymer nanoparticles templated by diblock copolymer micelles

Abstract

The combination of polymers with nanoparticles offers the possibility to obtain customizable composite materials with additional properties such as sensing or bistability provided by a switchable spin crossover (SCO) core....

Thermal hysteresis of stress and strain in spin-crossover@polymer composites: towards a rational design of actuator devices

“…Such matrix effects have notably been reported on the spin transition temperature, hysteresis width and kinetic properties. 29–33 Despite this considerable practical interest, the current knowledge about the effective thermomechanical properties of SCO@polymer composites remains largely incomplete, 13,14,17,19,20,34,35 making rational material and device designs difficult. Of particular interest would be to understand how efficiently one could transform the elastic strain energy stored in SCO particles 7 (up to several tenths of J cm −3 ) into a force or a stroke in a SCO@polymer composite material.…”

Morphology and orientation change of layer-by-layer deposited one- and two-dimensional coordination polymer nanocrystals containing rhodium paddle-wheel units

“…Coordination polymers and their subgroup of metal-organic frameworks are mainly studied in the literature for their suitability for gas storage, catalysis and their use in and as sensors. [1][2][3][4][5][6][7][8][9][10][11][12] For the latter, knowledge about the deposition behaviour of the compounds on interfaces is elementary. 13 The deposition of the particularly extensively characterized MOF HKUST-1 on functionalized gold surfaces by means of the so-called layer-by-layer process has been well studied.…”

Optimized Local Synthetic Conditions Induce Size Reduction and Phase Purification in {[Fe(Htrz)2(trz)](BF4)}n Spin Crossover Particles

“…For instance, block copolymers (BCPs) can form micellar structures because of the strong difference in solubilities between one block and the other in a given solvent. Depending on the ratio between each block, the size and amount of NPs embedded in this polymer can be tuned. , Additionally, other organic polymers have been used such as PVP (polyvinylpyrrolidone), PVA (polyvinyl alcohol), PEG (polyethylyneglycol), Triton, etc. with a less efficient control over the particle size. , The recent review by Salmon and Catala reports in a more exhaustive way the various approaches and uses of such SCO NPs …”
