We present a new family of supramolecular metallogels undergoing reversible multiphase transition triggered by temperature from amphiphilic alkynylplatinum(ii) complexes. Further investigation revealed that intermolecular PtPt and π-π stacking interactions facilitate such phase transitions upon increasing the temperature.
A chemical-responsive bis(m-phenylene)-32-crown-10/2,7-diazapyrenium salt [2]pseudorotaxane was prepared. It was found to form a supramolecular poly[2]pseudorotaxane in the solid state driven by π-π stacking interactions.
Chiral diporphyrin receptor 1, which has a macrocyclic cavity to sandwich aromatic guest molecules via double π-π stacking interactions, enabled the naked-eye detection of an aromatic explosive as well as chiral discrimination in NMR.
The (1)H NMR spectra of RNAs representing E. coli 23S rRNA helix 69 with [1,3-(15)N]pseudouridine modification at specific sites reveal unique roles for pseudouridine in stabilizing base-stacking interactions in the hairpin loop region.
A programmed assembly process produces rhombic grid networks from compounds L1-L4 in the crystal by pi-pi stacking interactions that generate a bimolecular grid synthon, which undergoes further NH...N hydrogen-bond-mediated assembly.
the stacking mechanism of the 1h-4h proton transfer in 4-pyridone, 4-pyridinthione and p-aminopyridineare constructed. for quantitative description of this process by means of the quamtumchemicalmethod density functional theory (dft) the activation energy (
