| 摘要 |
<p>The present invention concerns novel macromolecules, i.e. polypeptides having formula (I), wherein each of the groups Ri means independently the amino acid residue (II), (III), (IV), (V) and/or (VI), which over the carbon atom is bound to the frame, and Xi means a) an aliphatic long-chained hydrocarbon group which may contain double bonds, or b) an aliphatic long-chained hydrocarbon group which may contain double bonds, and which contains covalently bound a group Z which with an adjacent Z group may participate in the transfer of a photon, electron or proton, R' means hydrogen, lower alkyl, especially methyl or ethyl, benzyl or allyl, R'' means hydrogen, t-butyloxycarbonyl, benzyloxycarbonyl or fluorenylmethyloxycarbonyl, and the integer n indicates the number of repeating units, whereby the amino acids forming two consecutive units in the molecule are of opposite optical configuration, i.e. D and L, respectively. The compounds may be used for the manufacture of Langmuir-Blodgett films which, depending on the nature of the group Z, may be tailor-made to exhibit specific electrical properties, or in the case the side chains are saturated may be used as insulating films.</p> |
