A fluorescent and halochromic indolizine switch

An indolizine heterocycle switches from a nonemissive to an emissive form upon protonation. The co-entrapment of this molecular switch and a photoacid generator in polymer films allows the imprinting of fluorescent patterns in the resulting materials. These operating principles permit the writing and reading of information under optical control.

Instrumental and sensory analysis of Greek wines; Implementation of principal component analysis (PCA) for classification according to geographical origin

Wine is one of the most important products of Greece and other Mediterranean countries. Adulteration of wines, either in terms of geographical origin or variety, has been a major topic of debate and extensive research. Various instrumental methods (gas chromatography, high pressure liquid chromatography) and sensory analysis, in conjunction with statistical analysis, were developed and applied in an attempt to provide reliable answers to this issue. This research aimed at classifying 33 greek wines from various regions by employing both instrumental and sensory analysis. Application of principal component analysis (PCA) to our experimental data resulted in satisfactory classifications of only Greek red wines in terms of their geographical origin. Greek wines were effectively distinguished in two or three groups (depending on PCA figure); wines from Aegean/Ionean islands. North Greece and South Greece. However, further work with greater numbers of samples is required in order to draw more valid conclusions and to obtain a detailed map of greek wines according to their geographical origin and variety.

Syntheses of imidazo-, oxa-, and thiazepine ring systems via ring-opening of aziridines/Cu-catalyzed C-N/C-C bond formation

A simple and unpredicted synthetic pathway toward racemic and scalemic tetrahydrodibenzoimidazoazepines has been invented serendipitously proceeding through an SN2-type ring-opening of N-activated aziridines with 2-bromobenzylamine followed by a hitherto unprecedented cascade cyclization reaction sequence comprising a Cu-catalyzed cross dehydrogenation C-N coupling and an Ullmann C-C bond formation reaction. The tetrahydrobenzoxazepine and the tetrahydrobenzothiazepine derivatives have also been synthesized via the ring-opening of aziridines with 2-bromobenzyl alcohols and -mercaptan, respectively, followed by Cu-catalyzed N-arylation reaction.

A triphenylamine-based colorimetric and fluorescent probe with donor-bridge-acceptor structure for detection of G-quadruplex DNA

In this Letter, three triphenylamine-based dyes (TPA-1, TPA-2a and TPA-2b) with donor-bridge-acceptor (D-pi-A) structure were designed and synthesized for the purpose of G-quadruplexes recognition. In aqueous conditions, the interactions of the dyes with G-quadruplexes were studied with the aim to establish the influence of the geometry of the dyes on their binding and probing properties. Results indicate that TPA-2b displays significant selective colorimetric and fluorescent changes upon binding of G-quadruplex DNA. More importantly, its distinct color change enables visual detection and differentiation of G-quadruplexes from single and duplex DNA structures. CD titration date reveals that TPA-2b could induce and stabilize the formation of G-quadruplex structure. All these remarkable properties of TPA-2b suggest that it should have promising application in the field of G-quadruplexes research.
