Abstract:
A simple "solvent quenching" approach to align an alpha-helical end-grafted poly(gamma-benzyl l-glutamate) monolayer is presented. By sequentially treating poly(gamma-benzyl l-glutamate) with good solvent (chloroform) and bad solvent (acetone), we obtained a highly aligned monolayer with an average tilt angle as small as 3 degrees .
