Four novel receptors were designed and synthesized for colorimetric detection of F− ions. The introduction of four electron withdrawing groups into the backbone of the receptors makes the two phenolic groups efficient hydrogen bonding sites. The binding properties of receptors with anions were examined for the first time by UV–Vis, 1H NMR and fluorescence spectroscopies. The addition of F− resu...

The Cover Feature shows a fullerene molecule included in nanocage constructed from anthracene and triptycene units. strong affinity the supramolecular aromatic complex is attributed to multipoint CH⋅⋅⋅π interactions between cage host spherical guest. showed higher selectivity toward C70 compared C60.

a novel podand based anion receptor bearing benzimidazole motifs as recognition sites was designed and synthesized by reaction of 1,7-bis(2'-methylbenzoate)-1,4,7-trioxaheptane and phenylenediamine. the binding properties of anionic guest with this receptor were studied using uv-vis and fluorescence spectroscopy. these studies revealed that this receptor exhibit selective recognition towards f- ...

Emissive layers in phosphorescent organic light-emitting diodes commonly make use of guest–host blends such as Ir(ppy)3:CBP to achieve high external quantum efficiencies. However, while the blend has been studied experimentally, crucial questions remain regarding how exciton diffusion is dependent on distribution guest host, which can currently only be addressed at atomic level via computationa...

Clathrates are crystalline inclusion compounds formed by a physically stable reaction between host and guest molecules. Gas hydrate and hydroquinone (HQ) clathrate are one of the most studied and welldefined clathrate compounds. In this study, guest-free, CO2-loaded, CH4-loaded and CO2/CH4-loaded HQ clathrates were synthesized by gas-phase reaction and recrystallization. In addition, pure CO2 a...

The ability of an E-configured azobenzene guest to undergo photoisomerisation is controlled by the presence of a complementary host. Addition of base/acid allowed for a weakening/strengthening of the interactions in the divalent pseudo[2]rotaxane complex and hence could switch on/off photochromic activity.

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...

A new type of electron transfer (ET) system was built via the combination of a highly stable MOF host framework and methyl viologen guest molecule. The π-stacking arrangements adjust the distance between the D-A components, contributing to the formation of an ultra long-lived charge separated state in the photo/thermo dual stimuli-responsive complex.

Bisphosphorylpillar[5]arenes ( and ) were synthesized and used to study the host-guest complexation in organic solvents and water. The interactions between the guests and the phosphate of the hosts lead to strong binding towards alkyl dihalides and alkyldiammonium ions. may be used to detect or separate alkyl dihalides in water due to the rapid precipitation of the complex.
