Photo-controllable percolation of decorated nanoparticles in a nanopore: molecular dynamics simulation study

By means of molecular dynamics simulations we study formation of the wall-to-wall     percolation cluster in the solution of decorated nanoparticles in a pore. The model takes into account photo-switching between unpolar \trans\ and polar \cis-isomers of azobenzene. This leads to either colloidal dispersion of the particles or their aggregation     in a polar solvent. The dynamics of percolation cluster formation is analysed by applying a pulse-like illumination.

Synthesis and Electrooptical Properties of Side-Chain Polymethacrylates and Polycomplexes Containing Azobenzene Moieties with Different Length Spacers

We propose new structures of metal-containing azopolymers with changeable electro-optical properties depending on different length spacers. The new monomers – 4-{4-[4-(methacroyloxy)butoxy)phenyl]diazenyl benzoic acid, 4-{4-[4-(methacroyloxy)octyl)oxy]phenyl}diazenyl] benzoic acid and their complexes with Co and polymers based on these ones were synthesized. The influence of the electric field on the absorption spectra of new metal-containing azopolymers was investigated.
