Electrostatic Interactions in Host-Guest Complexes
In this article the quantum chemically calculated charge density distribution of 18-crown-6 and the K+ . . .l8-crown-6 complex are compared with the charge density distribution of smaller molecules and corresponding complexes which can be considered as fragments of the 18-crown-6 molecule. An analysis of the charge density distribution in terms of atomic charge distribution according to the sto...
متن کاملHost-guest interactions in acid-porphyrin complexes.
In this report we use the weak interactions of acid-porphyrin complexes to selectively bind competing acids to the faces of a rigid cyclic porphyrin dimer, and characterise the resulting interactions by NMR spectroscopy and nano-electrospray ionisation spectrometry.
متن کاملHybrid host-guest complexes: directing the supramolecular structure through secondary host-guest interactions.
A set of four hybrid host-guest complexes based on the inorganic crown ether analogue [H12W36O120]12- ({W36}) have been isolated and characterised. The cluster anion features a central rigid binding site made up of six terminal oxygen ligands and this motif allows the selective binding of a range of alkali and alkali-earth-metal cations. Here, the binding site was utilised to functionalise the ...
متن کاملCyclodextrin-based supramolecular nanoparticles stabilized by balancing attractive host-guest and repulsive electrostatic interactions.
Multicomponent, negatively charged supramolecular nanoparticles (SNPs) were formed by multivalent host-guest interactions without the need of a stopper in water and in PBS. Their size and stability are controlled owing to a balance of forces between attractive supramolecular and repulsive electrostatic interactions.
متن کاملNanometer arrays of functional light harvesting antenna complexes by nanoimprint lithography and host-guest interactions.
We show an approach based on a combination of site-directed mutagenesis, NIL and multivalent host-guest interactions for the realization of engineered ordered functional arrays of purified components of the photosynthetic system, the membrane-bound LH2 complex. In addition to micrometer-scale patterned structures, we demonstrated the use of nanometer-scale hard NIL stamps to generate functional...
