Cyclodextrin-based nanotubes have been widely investigated and their secondary assembly (SA) behavior was found in our previous works. Here we report the self-assembly behavior between lithium bis(trifluoromethylsulfonyl)imide (LiNTf 2 ) and b-cyclodextrin (b-CD). Nanosheet structures with regular shape were obtained in the concentrated LiNTf 2 @b-CD solution. This phenomenon can be explained in terms of the SA mechanism of CD induced by the inorganic guest LiNTf 2 . LiNTf 2 and b-CD firstly forms nanotubes, and the nanotubes further stack with each other to form nanosheets by SA. We confirm that the hydrogen-bonding interaction contributes a lot to the formation of the nanotubes and their SA, and Li ? shows a special effect in the SA by inducing hydrogenbonding network between the adjacent b-CD to regularly pack the nanotubes.

This review discusses supramolecular biofunctional materials, a novel class of biomaterials formed by small molecules that are held together via noncovalent interactions. The complexity of biology and relevant biomedical problems not only inspire, but also demand effective molecular design for functional materials. Supramolecular biofunctional materials offer (almost) unlimited possibilities and opportunities to address challenging biomedical problems. Rational molecular design of supramolecular biofunctional materials exploit powerful and versatile noncovalent interactions, which offer many advantages, such as responsiveness, reversibility, tunability, biomimicry, modularity, predictability, and, most importantly, adaptiveness. In this review, besides elaborating on the merits of supramolecular biofunctional materials (mainly in the form of hydrogels and/or nanoscale assemblies) resulting from noncovalent interactions, we also discuss the advantages of small peptides as a prevalent molecular platform to generate a wide range of supramolecular biofunctional materials for the applications in drug delivery, tissue engineering, immunology, cancer therapy, fluorescent imaging, and stem cell regulation. This review aims to provide a brief synopsis of recent achievements at the intersection of supramolecular chemistry and biomedical science in hope of contributing to the multidisciplinary research on supramolecular biofunctional materials for a wide range of applications. We envision that supramolecular biofunctional materials will contribute to the development of new therapies that will ultimately lead to a paradigm shift for developing next generation biomaterials for medicine.

SummaryIn the present work we report the synthesis of poly((4-hydroxy-3-(pyridin-3-yldiazenyl)phenethyl)methacrylamide-co-dimethylacrylamide) and its reversible optical and complex-forming properties due to copper and cyclodextrin (CD) interactions. Color changing effects are characterized by UV–vis spectroscopy and the supramolecular behavior is investigated by dynamic light scattering experiments.
