| Abstract | In this work we present a procedure to achieve nanoscale mesoporous materials. Previously we have shown using hydrogen bonded amphiphiles that polymeric comb-coil supramolecules leading to lamellar-within-cylindrical assembly allow preparation of hairy tubes, i.e. nanoscale empty tubes with polymer brushes at the wall. Here the concept is generalized: We use comb-coil supramolecules with lamellar-within-lamellar structure based on coordination bonding. Polystyrene-block-poly(4-vinylpyridine), PS-block-P4VP, is used with zinc dodecyl benzene sulphonate Zn(DBS)2, which coordinates to the lone electron pair of pyridine nitrogen of the latter block. Due to the physical nature of coordination bonding part of supramolecular template can be removed after the structure is formed by selective dissolution resulting in empty space between lamellae with polymer brushes at the walls. |
