In this work we demonstrates the development of coating polarizer based on guest-host effect between polymerizable liquid crystal monomer and dichroic dye. By optimization formulation guest dyes host crystals as well additives, have developed film possesses a single transmittance 32.5% polarization efficiency 99.3% with thickness 4.5um. Further optimizations should be done to improve properties...

Host systems with guest binding ability in water and/or biological fluids are a current challenge in supramolecular host–guest chemistry. Here we present the first syntheses of water-soluble N-ethanol ammonium resorcinarene chlorides (NARCls) with terminal hydroxyl groups at the upper rim. The NARCls possess deep cavities and are shown to bind a variety of guest molecules such as linear and cyc...

Single crystal X-ray diffraction analyses of the 2 : 1 complexes of phenazine with hydroquinone and 1,5-dihydroxynaphthalene and the 3 : 1 complex of phenazine with 4,4 ́-dihydroxybiphenyl have been performed. It is shown that in these complexes and also in the 3 : 1 complex of phenazine with 5,10-dihydrophenazine, phenazine forms a host framework consisting of onedimensional channels. The varia...

The development of stimulus-responsive polymeric materials is of great importance, especially for the development of remotely manipulated materials not in direct contact with an actuator. Here we design a photoresponsive supramolecular actuator by integrating host-guest interactions and photoswitching ability in a hydrogel. A photoresponsive supramolecular hydrogel with α-cyclodextrin as a host...

Ureidopyrimidinone functionalized pillar[5]arene (UPyP5) was synthesized and employed to complex with a bisparaquat derivative (G) to form supramolecular polymers at relatively high concentration. The orthogonal binding interactions including quadruple hydrogen bonding and host-guest interaction should play vital roles in the construction of this linear assembly.

Photochromism in a diarylethene derivative (1O) can be gated by a host-guest interaction where the thiazole orange groups are bound into the hydrophobic cavity of CB[8] in water. The closed-ring isomer (1C), which cannot be obtained freely in aqueous solution, survives even when the complex is dissociated by displacement from CB[8] by competition with 1-adamantanamine hydrochloride.

N-benzyl-tert-butyl nitroxide derivatives substituted at the aromatic ring form host-guest inclusion complexes with β-and γ-cyclodextrin. They were employed as probes to assess substituent effects on the geometry of the complex and on the kinetics of this complexation by combining EPR and (1)H NMR data.

The knowledge of the host-guest complexes using cyclodextrins (CDs) has prompted an increase in the development of new formulations. The capacity of these organic host structures of including guest within their hydrophobic cavities, improves physicochemical properties of the guest. In the case of pesticides, several inclusion complexes with cyclodextrins have been reported. However, in order to...

A responsive drug delivery system (DDS) for oxaliplatin (OX) has been designed with a view to overcoming several drawbacks associated with this anticancer agent, including fast degradation/deactivation in the blood stream, lack of tumor selectivity, and low bioavailability. The present approach is based on the direct host-guest encapsulation of OX by a pH-responsive receptor, carboxylatopillar[...

Supramolecular chemistry is a rapidly growing field, which has had remarkable impact on the life sciences on one hand and on materials sciences on the other. In the life sciences, the networks of noncovalent interactions between the constituents of cells, for example, have shifted into the current focus. Selfassembly, templation, self-sorting and multivalent binding all contribute to setting up...
