The Solid Channel Structure Inclusion Complex Formed Between Guest Styrene and Host c-Cyclodextrin
The solid complex of guest styrene included inside the channels of host c-cyclodextrin (styrene/c-CDchannel-IC) was formed in order to perform polymerization of styrene in a confined environment (c-CD channels). The experimental molar ratio of styrene to c-CD in styrene/c-CDchannel-IC was found to be 2:1, which is consistent with molecular modeling studies, utilizing Quantum Mechanics PM3 param...
متن کاملElectrostatic 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 کاملSurface modification of polymeric vesicles via host-guest inclusion complexation.
We have prepared a novel kind of building block (CD-PI-CD) of polyether imide (PI) with beta-cyclodextrin (beta-CD) at the both ends that self-assembles into vesicles in water. The vesicles are "reactive" in supramolecular chemistry because the host groups of beta-CD equally distribute on the inside and outside surfaces of the vesicles. Isothermal titration calorimetry (ITC) and static light sc...
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 ...
