Multianalyte Sensing of Addictive Over-the-Counter (OTC) Drugs

Abstract: A supramolecular sensor array composed of two fluorescent cucurbit[n]uril-type receptors (probe 1 and probe 2) displaying complementary selectivities was tested for its ability to detect and quantify drug-related amines. The fluorimetric titration of the individual probes showed highly variable and cross-reactive analyte-dependent changes in fluorescence. An excellent ability to recognize a variety of analytes was demonstrated in qualitative as well as quantitative assays. Importantly, a successful quantitative analysis of several analytes of interest was achieved in mixtures and in human urine. The throughput and sensitivity surpass those of the current state-of-the-art methods that usually require analyte solid-phase extraction (SPE). These results open up the opportunity for new applications of cucurbit[n]uril-type receptors in sensing and pave the way for the development of simple high-throughput assays for various drugs in the near future.

Solvent Switching between Charge Transfer and Intraligand Excited States in a Multichromophoric Platinum(II) Complex

Abstract: The photophysical properties of a new multichromophoric platinum(II) complex, Pt(dbbpy)(C≡C−nap)2 (1) (dbbpy = 4,4‘-(di-tert-butyl)-2,2‘-bipyridine; C≡C−nap = 1-ethynylnaphthalene), is reported in four different solvent systems of varying polarity: toluene, 2-methyltetrahydrofuran, dichloromethane, and acetonitrile. Since the low-energy dπ Pt → π* dbbpy metal-to-ligand charge transfer (MLCT) transitions in this chromophore are negative solvatochromic in nature, increasing solvent polarity raises the energy of the MLCT state. At the same time, the low-lying, metal-perturbed π,π* triplet intraligand (3IL) state present within the molecule on the −C≡C−nap fragments are largely invariant to solvent polarity as evidenced by the absorption and emission properties of the model chromophore lacking the low-energy charge transfer state, Pt(dppe)(C≡C−nap)2 (2) (dppe = 1,2-bis(diphenylphosphino)ethane). In solvents of low polarity, the static and dynamic absorption and luminescence spectroscopy of 1 are largely cons...

An ecological momentary assessment of relapse crises in dieting.

Abstract: Much of the research on relapse crises in dieting has focused on isolated lapse events and relied heavily on retrospective self-report data. The present study sought to overcome these limitations by using ecological momentary assessment (EMA) techniques to examine situations of dietary temptation and lapse with a sample of obese, formerly sedentary, postmenopausal women (N = 37) during the final week of a weight-loss intervention. Mood was associated with reports of dietary lapse. Abstinence-violation effects were more strongly associated with dietary lapses than temptations. Finally, coping responses distinguished dietary temptations from lapses. Education on the factors associated with relapse crises in dieting may be imperative for weight loss success and maintenance.
