The memory-driven order-disorder transition of a 3D-supramolecular architecture based on calix[5]arene and porphyrin derivatives

A 3D supramolecular polymer based on calix[5]arene tetheredpoly(p-phenyleneethynylene) with a complementary porphyrinendowed with alkanediyldiammonium functions is prepared insolution but, collapses when transferred to a chemically inert solidmatrix forming a dispersion of de-phasing porphyrin aggregates.We found that a short thermal shock induces the de-aggregationof the porphyrin aggregates, and a partial restoration of theoriginal 3D-supramolecular architecture.
