Abstract:

Three main types of light-sensitive polyaminoacids PAA such as rod-like dyes contained photoactive rotaxanes and inorganic-organic cyclophosphazene hybrids are considered in the context of intelligent materials creations. Light-manipulative biomimetics preparation involves strategy via combinatorial synthesis computation and modelling of possible molecular architecture self-organization and supramolecular phase formation function on nanoscale stimula-responsive study intelligent materials formation. Modified polyglutamic acid with dyes regular set possesses specific ability to self-assembly with cooperative rearrangement under outer temperature carbocyanines bonded, pH fluoresceine bonded. Ion-sensitivity of photoactive peptide oligo-glutamic or oligo-glycine rotaxanes is a promising feature for molecular switches construction. Inorganic-organic hybrids with cyclophosphazene cores star-like design of poly-glutamic or poly-alanine are the convenient matrixes for different fragments immobilization that can result in light-controlled conformation of PAA in variable states solution, gel, film.
