Abstract Self-assembly of multiple building blocks via hydrogen bonds into well-defined nanoconstructs with selective binding function remains one the foremost challenges in supramolecular chemistry. Here, we report discovery a enantiopure nanocapsule that is formed through self-assembly eight amino acid functionalised molecules nonpolar solvents 48 bonds. The remarkably robust, being stable at low and high temperatures, presence base, presumably due to co-operative geometry bonding motif....
The development of efficient fluorescent sensors for detecting anions is paramount importance due to the critical roles that play in biological systems, environmental processes, and industrial applications. Sensitive selective detection methods are essential monitoring complex competitive environments. Herein, we report synthesis photochemical properties a novel sensor designed inorganic organic media. based on charge‐neutral europium (III) complex, formed through coordination Eu3+ ions with...
Abstract Noncovalent self‐assembly creates an effective route to highly sophisticated supramolecular polymers with tunable properties. However, the outcome of this assembly process is dependent on external conditions. In work, a monomeric naphthalene diimide (NDI), designed allow solubility in wide range solvents, can assemble into three distinct noncovalent species depending solvent composition and temperature. Namely, while chlorinated solvents yields relatively short, hydrogen‐bonded...
We report on the characterization of two imine type ligands containing photoresponsive azobenzene units as side groups and their transition metal ions complexes.
Complexation of metal ions by a ligand bearing azobenzene linker yielded two types complexes: an [M 2 L ] 4+ metallocycle and 4 6 8+ tetrahedral cage, which can be further converted into libraries mononuclear [M(L′/L′′) n 2+ species.
Herein we report the self-assembly of an amino-acid substituted tetraphenylethylene (TPE) into a hydrogen-bonded dimeric capsule. Depending on conditions applied presented TPE derivative exhibits bluish photoluminescence with QYs up to 24% due AIE effect and excimer formation.
The functionalization of a spherical Keplerate-type polyoxometalate {Mo<sub>72</sub>V<sub>30</sub>} with cationic azobenzene surfactant has been achieved through ionic self-assembly.
The hierarchical self-assembly of l-tyrosine substituted naphthalenediimide has been explored in solution by NMR spectroscopy and the solid-state atomic force microscopy. Spontaneous non-covalent polymerisation led to formation a three-dimensional fibre-like supramolecular polymer with n-type semiconducting properties.
The non-covalent aggregation of four benzene-1,3,5-tricarboxamide (BTA) derivatives formed from glycine or l-valine esters (-Me, -iPr), has been investigated in the solid-state and chloroform solution by means several analytical methods (NMR, FT-IR, single crystal XRD). Two types self-assembled structures were characterized: a dimeric capsule –NH···OC- (ester) bonding columnar assembly with characteristic (amide) bonds (alongside monomers). In-depth studies revealed significant role steric...
A bifunctional ligand 4,4-dimethyl-1-(pyridin-4-yl)pentane-1,3-dione (HL) able to provide two distinct coordination sites, i.e. anionic β-diketonate (after deprotonation) and neutral pyridine, has been used in the synthesis of Ag(I), Pd(II) Pt(II) complexes that then have applied as metalloligands for construction new heterometallic polymeric materials. The ambidentate nature L- enables switching between different modes within mononuclear or their conversion into species a fully controllable...
We describe here the generation of new donor-acceptor disulfide architectures obtained in aqueous solution at physiological pH. The application a dynamic combinatorial chemistry approach allowed us to generate large number macrocyclic together with type [2]catenanes consisting four distinct components. Up fifteen types structurally-distinct have been generated through one-pot exchange reactions between thiol-functionalized distribution products formed was found be strongly dependent on...
Small π-conjugated molecules can be designed and synthesized to undergo controlled self-assembly forming low-dimensional architectures, with programmed order at the supramolecular level. Such is of paramount importance because it defines property obtained material. Here, we have focused our attention four pyromellitic diimide derivatives exposing different types side chains. The joint effect noncovalent interactions including π–π stacking, H-bonding, van der Waals forces on yielded...

Harnessing geometrical electrical changes in response to multiple external stimuli on level modulate properties remains a fundamental challenge. Herein, reversible formation aggregates l ‐tyrosine E ‐azobenzene‐tetracarboxamide ( ‐ ABT ) is shown be finely controlled by light, solvent,...

Here, we report a reaction cascade employing the substituent-induced post-assembly modification of Co(iii) complex. Unexpectedly, found that (triisopropylsilyl)alkynyl moiety introduced to Sonogashira with bromo-functionalized assembly plays "Trojan horse" role, triggering subsequent, second step cascade, i.e. Co(ii) reduction. The reported substituent-activated Sonogashira-redox might set new direction in construction specific chemical sensors.
Hydrogen-bonded polymers are a class of highly dynamic supramolecular aggregates, whose self-assembly may be tuned by very mild external or internal stimuli. However, the rational design chiral supramolecules remains challenging especially when flexible components involved. The combination inherent weakness and nature intermolecular bonds that hold together such assemblies with unrestricted molecular motions introduces additional factors which affect process. In this report, four amino...
