Cooperative self-assembly and gelation of organogold(i) complexes via hydrogen bonding and aurophilic Au⋯Au interactions

Abstract

With the synergistic combination of intermolecular Au(i)-Au(i) and hydrogen bonding interactions, a rod-coil alkynyl-gold(i)-isocyanide monomer tends to form supramolecular fibers and gels via a cooperative nucleation-elongation self-assembly mechanism, which display Ag(i) ion-triggered responsiveness.

Recent Progress on Supramolecular Luminescent Assemblies Based on Aurophilic Interactions in Solution

“…So, upon addition of MeOH, self-assembly assisted by aurophilic interactions and other noncovalent forces occurred in order to minimize the contact between the apolar groups and the polar solvent. The same year, the alkynyl-gold(I)-isocyanide metallogelator 76 was reported by Wang et al [52]. The complex was able to form a reversible supramolecular gel in an apolar methylcyclohexane/CHCl 3 (95:5, v:v) solution (Figure 29A).…”

Au(i)-, Ag(i)-, and Pd(ii)-coordination-driven diverse self-assembly of an N-heterocyclic carbene-based amphiphile

“…1 H-NMR spectra were recorded on a Bruker NMR spectrometer (Avance 400, Bruker Biospin Co., Inc., USA) operated at 400 MHz. 13 C-NMR spectra were recorded on the same instrument operated at 100 MHz. All the NMR spectra were recorded in CDCl 3 .…”

“…All the NMR spectra were recorded in CDCl 3 . Both the 1 H-NMR and 13 C-NMR spectra were calibrated using tetramethylsilane as an internal reference. Elemental analyses were carried out using a Flash 2000 instrument (Thermo Fisher Scientic Inc., USA).…”

“…S1 and S3, ESI †). In the 13 C NMR spectra, the chemical shis for the carbenoid carbons were found at 173.6 ppm (Fig. S2 and S4, ESI †) for Au-MS and 180.3 ppm for Ag-MS. 11 Notably, the carbenoid carbon of Ag-MS appeared as singlet.…”

Aggregation and Tunable Color Emission Behaviors of l‐Glutamine‐Derived Platinum(II) Bipyridine Complexes by Hydrogen‐Bonding, π–π Stacking and Metal–Metal Interactions

“…More recently, transition‐metal coordination complexes with unique square‐planar structures were explored for the construction of functional materials due to their ability to form intermolecular π–π stacking and metal–metal interactions, thus inducing intriguing luminescence properties ,. One example are the platinum(II) polypyridine complexes which have been extensively investigated ,.…”
