Gold nanoparticles （AuNPs） functionalized with supramolecular macrocycles are versatile and diverse hybrid nanomaterials, which combine and enhance the characteristics of the two components. In this mini-review, we summarize the recent research progress on the synthesis and assembly of AuNPs functionalized with different supramolecular macrocyclic compounds, i.e., crown ethers, cyclophanes, cyclodextrins （CDs）, cucurbit[n]urils （CB[n]）, calix[n]arenes, and pillar[n]arenes （PIn]A）. Meanwhile, applications of these supramolecular hybrid nanomaterials in the fields of sensors, biomedicine and plasmonic devices are also presented.

Tunable luminescent materials are becoming more and more important owing to their broad application potential in various fields. Here we construct a pillar[5]arene-based hybrid material with stimuli-responsive luminescent properties and ion-sensing abilities from a pyridine-modified conjugated pillar[5]arene and a planar chromophore oligo(phenylenevinylene) upon coordination of Cd(II) metal cores. This new material not only shows an optimized luminescence due to the minimized π–π stacking and efficient charge transfer properties benefitting from the existence of pillar[5]arene rings, but also exhibits tunable multicolor emission induced by different external stimuli including solvent, ions and acid, indicating great application potential as a fluorescent sensory material, especially for Fe3+. With this pillar[5]arene-based dual-ligand hybrid material, valid optimization and regulation on the fluorescence of the original chromophore have been achieved, which demonstrates a plausible strategy for the design of tunable solid-state luminescent materials and also a prototypical model for the effective regulation of fluorescent properties of planarπ systems using synthetic macrocycle-based building blocks.

In recent years, cancer has become the number two cause of death around the world, and scientists have exploited various treatment maps. Calixarenes, with diversified features, have been widely applied into drug delivery systems, which can respond to multi-stimuli and exhibit excellent performance. In this mini-review, we summarize the recent advances on controlled drug delivery systems based on calixarenes, in the form of inclusion complexes, amphiphilic self-assembly nanocarriers including micelles, hydrogels, vesicles and liposomes, and supramolecular nanovalves on mesoporous silica nanomaterials.

A fluorescent supramolecular polymer network with an excellent triple-stimuli responsive property based on metal-ligand coordination and host-guest interactions has been constructed from a terpyridine-monofunctionalized leaning tower[6]arene,a tetraphenylethylene AIEgen,and a bridging coordination ion(Zn^2+).Addition of competitive binding agents,trifluoroacetic acid,and/or pillar[5]arene can break the metal coordination and/or host-guest inclusion complexation,and thermal heating can weaken the non-covalent interactions in the supramolecular polymer gel,all leading to the gel-to-sol transition.
