title: A new backbone of artificial enzymes obtained by cross-linkage of poly(ethylenimine).
abstract: Cross-linkage of the branches of poly(ethylenimine) (PEI) suppresses flexibility of the polymer as revealed by decreased affinity of the amino groups on PEI backbone towards proton or Ni(II) ion. The cross-linkage improves ability of the PEI derivative equipped with beta-cyclodextrin to deacylate an ester containing t-butylphenyl moiety.
