Abstract

Abstract : A 3D-supramolecular structure, "pre-formed" in solution, collapses when transferred to a solid matrix: a short thermal shock partially restore the original 3D-architecture. Abstract : A 3D supramolecular polymer based on calix[5]arene tethered poly( p -phenyleneethynylene) with a complementary porphyrin endowed with alkanediyldiammonium functions is prepared in solution but collapses when transferred to a chemically inert solid matrix forming a dispersion of de-phasing porphyrin aggregates. We found that a short thermal shock induces the de-aggregation of the porphyrin aggregates, and a partial restoration of the original 3D-supramolecular architecture.
