Design of PolyMOCs and the synthesis of crosslinkers for the BASP platform
… integration of metal-organic cages (MOCs) into polymers were explored. The first strategy creates Block Co-PolyMOCs (BCPMOCs), which feature the integration of MOCs into block copolymers (BCPs). In the first assembly step, BCPs functionalized with a bispyridyl ligand on the chain end undergo Pd …

Investigation of Copper Wire-Mediated Controlled/Living Radical Polymerization
Copper wire mediated controlled living radical polymerization (CLRP) is a powerful tool that provides numerous opportunities for the development of new materials. It requires low catalyst loading and mild reaction conditions, but does involve use of organic solvents. There is a need for greener …

Effect of structure and plasticizer on the glass transition of adsorbed polymer
<p>"The effect of molecular mass on adsorbed poly(methyl methacrylate) (PMMA) on silica was determined using temperature-modulated differential scanning calorimetry (TMDSC). A two-component model, based on loosely-bound polymer (glass transition temperature, T<sub>g</sub>, similar to that of bulk) …

Mechanical and optical characterization of force induced chemical reactions in solid state linear polymers
… chemical species (mechanophores) into polymer backbones, mechanical force can drive chemical reactions. Mechanophores have been developed with potential as damage sensing, self-healing, and self-reinforcing materials. This research investigates the conditions for promoting mechanophore …

Control of mechanochromic reactions in a polymer matrix
… and recently developed naphthopyran (NP), in polymeric matrices. First, the effect of force on the rate constants and activation energies for SP–merocyanine (MC) transition is characterized in bulk polymers. Under different values of a macroscopic tensile stress, the change in fluorescence …

Spiropyrans as color-generating mechanophores
… reaction products and smart materials such as polymers that response to mechanical stimuli. Mechanically responsive polymers are already known, but they generally rely on the disruption or formation of non-covalent bonds. Expanding their scope to include covalent bond changes in force-sensitive …
