Copillararene convoy: A linear supramolecular polymer can be efficiently constructed in solution with a copillararene monomer (see picture). Single‐crystal X‐ray analysis and NMR spectroscopy revealed that aggregation was enthalpically driven by quadruple CH⋅⋅⋅π interactions between the octyl tail (blue) and the aromatic cavity (red).

Core-shell structured dual-mesoporous silica spheres (DMSS) that possess smaller pores (2.0 nm) in the shell and larger tunable pores (12.8-18.5 nm) in the core have been successfully synthesized by utilizing an amphiphilic block copolymer (polystyrene-b-poly (acrylic acid), PS-b-PAA) and cetyl trimethyl ammonium bromide (CTAB) as cotemplates. The thickness of the shells and the larger pore size in the core could be easily tuned by changing the amounts of TEOS and the hydrophobic block (PS) length during synthesis, respectively. By encapsulating hydrophobic magnetite nanoparticles into the cores, superparamagnetic dual-mesoporous silica spheres were obtained. Drug storage and release testing results showed that the diffusing rate of the stored drug could be efficiently controlled by changing the shell thickness of DMSS.

A simple seed-mediated growth route is developed to fabricate monodisperse, uniform superparamagnetic Fe(3)O(4) core/gold shell structured nanocomposites with tunable sizes and optical properties, in which gold seed formation and attachment onto the core surface via S-Au covalent bonding proceeds almost simultaneously in the one-pot synthesis. The as-prepared nanocomposite is demonstrated to have a great potential for magnetic resonance imaging (MRI)-guided, focused photothermal tumor therapy under near-IR laser radiation.

A host–guest recognition motif based on a crown ether moiety was employed to construct a supramolecular polymer gel from a low molecular weight A–B monomer. Reversible thermo‐ and pH‐induced gel–sol transitions of the dual‐responsive gel are demonstrated for the controlled release of rhodamine B.

Bildet eine Kette: Ein Copillararen‐Monomer bildet in Lösung ein lineares supramolekulares Polymer (siehe Bild). Einkristall‐Röntgenstrukturanalysen und NMR‐Spektren belegen die enthalpisch angetriebene Aggregation über vierfache CH⋅⋅⋅π‐Wechselwirkungen zwischen dem Octylrest (blau) und dem mit aromatischen Gruppen ausgekleideten Hohlraum (rot).
