Abstract The intriguing effect of metal ions and biomolecules on various biological entities warrants developing selective sensitive fluorescent chemosensors in water other organic solvents. A review comparable literature related areas, including material chemistry, environmental science, supramolecular indicates that most the research work is carried out varying types existing chemosensor explores use solvents, DMSO/H₂O, methanol, DMF/HEPES systems, photoinduced electron transfer (PET)‐based chemosensors. DMSO DMF are strong polar solvents resulting fluorescence emission. Additionally, dichlorobenzene chlorobenzene employed to form gels with urea compounds, further improving sensor's functionality selectivity. Also, parallel investigations, when as a solvent, revealed decrease binding/ detection ability guest analytes since molecules strongly solvated (hydrated) moieties, whereas non‐polar (or amphiphilic molecules) found aggregations or self‐assemblies. present attempts analyze characterize water‐soluble (FCHs) into cyclic acyclic per their topological structural architectures. In addition, seminal examples synthetic FCHs, included herein, provide an understanding rational designs, fundamental properties, interactions, emerging switchable properties aqueous medium. Thus, knowledge these high affinity selectivity would facilitate synthesis novel FCHs potential future applications.

Exploring the Differences in Self‐Assembly Behavior, Structure, and Properties of Two Novel Pentanuclear Zinc (II) Salamo‐Type Complexes Possessing Solvent Effect

ABSTRACT A salamo‐type biscompartmental ligand was successfully prepared. On this basis, two novel pentanuclear zinc (II) complexes possessing solvent effect were self‐assembled with different salts: [Zn 5 (L) 2 ( μ ‐OAc) (CH 3 COCH )] 1 ) and CN)] ). Complex contains fully deprotonated 4− units, five Zn(II) atoms, coordinating acetate anions, one acetone molecule. The atoms are all in a slightly distorted triangular bipyramidal geometrical configurations. consists of anions acetonitrile structures the self‐assembling may be attributed to various effects applied self‐assembly. As result, involved bridging coordination, thereby expanding distance between secondary building units (SBUs). In addition, polar nonprotonic solvents, especially molecules, coordination process. Finally, reaction sites intermolecular interactions further discussed by MEP, IRI, Hirshfeld surfaces, their fluorescence properties explored.

Salamo‐type ligand H 2 L was designed and synthesized reacted with Cu (II) Zn acetate, respectively, to obtain two binuclear complexes: [Cu (L) ]·2CH 3 OH ( 1 ) [Zn ] having the same coordination number but distinct geometries. Complex is a complex containing crystalline ethanol molecules, where atoms are surrounded by utterly deprotonated 2− parts, forming slightly twisted tetragonal pyramidal configurations of pentacoordinate. In , parts surround atoms, pentadentate triangular bipyramidal configurations. The complexes were elucidated via IR analyses ultraviolet spectroscopy. Using DFT theoretical calculation, MEPs, IRI, Hirshfeld surface analysis investigate further molecular interactions reaction sites. Ultimately, fluorescence characteristics its discussed.
