Pillararenes and their derivatives have emerged in supramolecular chemistry as unique macrocycles for applications in host-guest chemistry, materials science and biomimetics. Many variations have been conceived and synthesized in recent years and in this review, we relate progress in water-soluble versions: leaning towerarenes, extended-pillararenes, biphenarenes, helicarenes and octopusarenes. These are applied in targeted drug delivery, selective uptake and release of aromatic guests, fabrication of gold/silver and mesoporous silica nanoparticles, cell imaging, pollutant separation, biomedicine (e.

Cardiac fibroblasts are activated following myocardial infarction (MI) and cardiac fibrosis is a major driver of the growing burden of heart failure. A non-invasive targeting method for activated cardiac fibroblasts would be advantageous because of their importance for imaging and therapy. Targeting was achieved by linking a 7-amino acid peptide (EP9) to a perfluorocarbon-containing nanoemulsion (PFC-NE) for visualization by F-combined with H-MRI.

As common complications of diabetes, long-term hyperglycemia and inflammatory infiltration often lead to prolonged unhealing of chronic diabetic wounds. The natural hydrogel-containing plant polysaccharides were recorded to have effective hypoglycemic and anti-inflammatory effects. This study focused on the accelerating effect of diabetic wound healing of hydrogels doped with polysaccharide (DOP)─calcium carbonate (CaCO) microspheres, which have glucose-responsive insulin release and anti-inflammatory effects.

The scalable synthesis of figure-eight π-systems is challenging for the conventional bottom-up approach. We have recently reported that the oxidative inner-bond cleavage of commercially available dibenzo[g,p]chrysene efficiently furnishes a figure-eight π-acceptor, cyclobisbiphenylenecarbonyl (CBBC), in large quantity. Furthermore, its donor-acceptor-type derivative with four N-carbazolyl substituents at the meta-positions of the carbonyl groups exhibited thermally activated delayed fluorescence (TADF) and circularly polarized luminescence (CPL) with a high |gCPL| value of 1.
