Dumbbell fullerene 1 and ditopic bisdouble-calix[5]arene 2 were synthesized. Their iterative host-guest complexations create the supramolecular nano network. Scanning electron microscopy revealed the formation of the branched fiber, possessing a length of more than 100 mum and widths of 250-500 nm on a glass plate. More detailed information was given by atomic force microscopy. The formed fibers on

The formation of bio-inspired healable lanthanide luminescent hydrogels is detailed. These materials are composed of K(I)-stabilized guanosine quadruplexes (G4) that were bio-conjugated to mannose-derived picolinic acid ligand 1 using boric acid chemistry (G4-1). The supramolecularself-assembly between G4-1 and europium (Eu(III)) was confirmed, including the use of time-gated luminescence spectroscopy
