Larger Groups, Smaller Enantioselectivity? Two Anthracene-Containing, Pyridino-Crown Ether-Based Fluorescent Sensor Molecules

Formation of Supramolecular Polymers from Homoditopic Molecules Containing Secondary Ammonium Ion and Crown Ether Moieties

A New Saccharides and Nnucleosides Sensor Based on Tetrathiafulvalene-anthracene Dyad with Two Boronic Acid Groups

A new saccharides sensor based on the TTF-anthracene dyad with two boronic acid (2) groups was designed and synthesized. This new saccharides sensor shows selectivity towards D-glucose while its analogue with one boronic acid group (1) was reported to bind D-Fructose selectively. Moreover, reaction of compound 2 with uridine induced even larger fluorescence enhancement under the same condition.

A new optical/electrochemical Na+ sensor based on platinum(II) complexes containing crown ether annelated dithiolate ligands.

Two new platinum(II) complexes containing both 4,4'-di-tert-butyl-2,2'-bipyridine (dbbpy) and crown ether annelated dithiolate ligands, [Pt(dbbpy)(3O-C2S4)] (, 3O-C2S4(2-)=1,4,7-trioxa-10,13-dithiacyclopentadec-11-ene-11,12-dithiolate) and [Pt(dbbpy)(4O-C2S4)] (, 4O-C2S(4)2-=1,4,7,10-tetraoxa-13,16-dithiacyclooctadec-14-ene-14,15-dithiolate), have been prepared and characterized. These two comp...

Predicting Customer-Expectation-Based Warranty Cost for Smaller-the- Better and Larger-the-Better Performance Characteristics

The quality loss function assumes a fixed target and only accounts for immediate issues within manufacturing facilities whereas warranty loss occurs during customer use. Based on the two independent variables, product performance and consumers’ expectation, a methodology to predict the probability of customer complaint is presented in this paper. The formulation presented will serve as a basic ...

Responsive supramolecular gels constructed by crown ether based molecular recognition.

Responsive supramolecular gels were constructed from crown ether terminated four-arm star poly(epsilon-caprolactone) (PCL-DB24C8) and dibenzylammonium-terminated two-arm PCL-DBAS (see scheme), exploiting the formation of pseudorotaxane linkages between crown ether and ammonium moieties. The resultant supramolecular gels exhibit thermo- and pH-induced reversible gel-sol transition.
