Biomimetic Polyaminoacids as Precursors for Optical-Active Intelligent Materials
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.
