Recently there has been a great deal of interest and associated research into aspects of the coordination chemistry of lanthanides and bismuth—elements that show intriguing common features. This work focuses on the synthesis and characterization of a novel bismuth(III) polynuclear metallamacrocyclic complex derived from aminohydroxamic acid, in order to compare the coordination ability of Bi3+ with the similarly sized La3+ ions. A polynuclear tyrosinehydroximate Bi(OH)[15-MCCu(II)Tyrha-5](NO3)2 (1) was obtained according to the synthetic routes previously described for water-soluble Ln(III)-Cu(II) 15-MC-5 metallacrowns. Correlations between structural parameters of Bi(III) and Ln(III) complexes were analyzed. DFT calculations confirmed the similarity between molecular structures of the model bismuth(III) and lanthanum(III) tyrosinehydroximate 15-metallacrowns-5. Analysis of the electronic structures revealed, however, stronger donor-acceptor interactions between the central ion and the metallamacrocycle in the case of the lanthanum analogue. Thermochromic properties of 1 were studied.

Water-soluble luminescent semiconductor nanocrystals also known as quantum dots (QDs) that have prominent photostability, wide absorption cross sections and tunable narrow emission, have been shown as promising probes in immunoassays. QDs are often used as donors in fluorescence resonance energy transfer (FRET) based sensors using organic dyes or fluorescent proteins as acceptors. Here, the FRET between a QD donor and fluorescent protein acceptors has been studied. The fluorescent protein (FP)mCherry appended with a hexa-histidine-tag could effectively self-assemble onto CdTe to produce small donor-acceptor distances and hence highly efficient FRET (efficiency > 80%) at relatively low FP: CdTe copy numbers (ca.1). Using the Förster dipole–dipole interaction formula, the Förster radius (R0) and respective donor-acceptor distances for the CdTe -FP FRET systems have been calculated. The binding constants (Kd) of the QD-FP systems have also been evaluated by the emission spectra.

ABSTRACTThe synthesis and self-assembly of a water-soluble, tricyclic, self-complementary heterocycle that features the hydrogen bond donor-acceptor arrays of both guanine (G) and cytosine (C) juxtaposed between a pyridine ring is presented. In solution, this tricycle, which has been termed xK1, self-assembles into Rosette Nanotubes (RNTs) that have an inner diameter of 1.4 nm. Unlike the RNTs formed from the bicyclic congener K1, we demonstrate that xK1 with its extended ð system, forms a J-type RNT assembly determined through UV-Vis, CD and fluorescence spectroscopy experiments. This observation brings the possibility of developing electrically conducting RNTs for applications in the areas of photovoltaics and molecular wires.
