  Switching among logic XNOR, IMPLICATION and INHIBIT gates at molecular level and selectively sensing of Cu2+

  摘要：

  In this work, 2-(5-methylpyridine-2-yl)imidazole was synthesized to perform a fluorescence sensing system depending on the imidazole derivative as a sensor for Cu2+. According to the required measurements, the imidazole derivative was shown to be used as a sensing agent for Cu2+ with the low detection limit of 1.70 mu M and quantitation limit of 5.65 mu M. Binding ratio was found as 1:1 by using Job's plot. To present the interactions of copper ions and EDTA with the target sensor, H-1 NMR titration measurements were done. Logic gate applications in the presence of EDTA and Cu2+ were investigated. When three outputs (at 372 nm, 395 nm and 418 nm) were examined in 2(4) cases of the two inputs (Cu2+ and EDTA), three different logic gates were obtained as XNOR, IMPLICATION and INHIBIT, respectively.

  A series of the pyridine-imidazole (PyIm) Cu(I) complexes with different substituents (bromide (P1), methyl (P2), and phenyl (P3)) attached on the pyridine ring are synthesized and characterized. All the complexes show the typical metal-to-ligand charge transfer (MLCT) absorption in the visible region. Complex P1 with an electron-withdrawing substituent on the pyridine ring, e.g., a bromine group, shows a red shift of the emission wavelength. Conversely, an electron-donating substituent on the pyridine ring in complex P2, e.g., a methyl group, shifts the emission to longer wavelength. Similarly, complex P3 containing the extended pi-conjugation system of the ligand also exhibits a red shift of the emission wavelength. All of the complexes exhibit efficient green-yellow emission in PMMA films at room temperature with emission wavelength of 547-569 nm and quantum yields of 24.8-53.0%. Meanwhile, DFT and TDDFT methods were employed to explain the photophysical properties.

  An object of the present invention is to provide a novel structure that enables one-dimensional arraying of metal atoms and can stably exist. The present invention relates to a double-stranded oligonucleotide derivative, which contains two oligonucleotide derivatives each containing at least one nucleotide derivative wherein a base portion of a nucleotide is substituted with a metal coordination group that is resistant to oxidation and metal atoms, wherein the double strands are formed by coordination of each metal coordination group contained in each oligonucleotide derivative to a metal atom so as to form a complex.
