“…[3][4][5][6][7][8][9][10][11] In recent years, considerable efforts have been made to take advantage of rhodamine dyes in constructing fluorometric probes for metal ions, [12][13][14][15][16] and a number of excellent fluorescent probes for Cu 2+ or Hg 2+ have been reported. [17][18] However, the probes that can sense two or more mental ions separately were rarely reported. [19][20][21] In the present work, a novel fluorescent probe (RD) based on dansyl-appended rhodamine B was designed and synthesized for detection of Hg 2+ and Cu 2+ (Scheme 1).…”

A novel fluorescent probe based on dansyl-appended rhodamine B was developed. The probe can selectively recognize and sense Hg 2+ and Cu 2+ from other common metal ions by showing unique fluorescence and absorption characteristics. In MeCN/HEPES buffer solution, the probe gives a ratiometric fluorescent response to Hg 2+ , which was ascribed to the fluorescence resonance energy transfer from dansyl moiety to the ring-opened rhodamine B moiety, while the presence of Cu 2+ causes fluorescence quenching. Beside the fluorescence change, the presence of Cu 2+ and Hg 2+ can induce intensive absorption at about 555 nm, which resulted in a color change from colorless to pink.

Özet: Polimerik bakır (II) komplekslerinin tasarımı ve sentezi, moleküler biyoloji, manyetizma ve fotolüminesans alanlarındaki potansiyel uygulamalarından dolayı büyük ilgi uyandırmaktadır. Bu çalışmada, fotolüminesans özellikler gösteren {Cu4O4} kübik formda, C38H40Cl4Cu4N4O10 (1) kompleksi rapor edilmektedir. Kompleks 1, solvotermal reaksiyon ile sentezlendi ve element analizi, FT-IR, katı UV-Vis spektroskopisi ve tek kristal X ışını kırınımı ile karakterize edildi. Kristal yapı çalışmaları, kompleks 1 in kristal yapısındaki dört çekirdekli birimdeki bakır(II) iyonlarının bozulmuş kare piramit geometriye sahip olduğunu gösterdi. Kompleks 1 ve ligandı H2L'nin katı durumdaki fotolüminesans özellikleri ise görünür bölgede oda sıcaklığında incelendi. Kompleks 1 ve ligandı H2L UV ışık ile 349 nm de uyarıldığı zaman, kompleks 1 görünür bölgede 452 nm'de şiddetli mor emisyon gösterirken, ligandı H2L 504 nm'de yeşil emisyon göstermektedir. Bu umut verici fotolüminesans davranış, bu tip bileşikler için duyarlı moleküler cihazlar veya organik ışık yayan diyotlar (OLEDs) için olası uygulamalara kapı açmaktadır. Investigation of Abstract:The design and synthesis of polymeric coordination copper(II) complexes are of great interest due to potential applications in the areas of molecular biology, magnetism and photoluminescence. In this study, reports the cubane-type {M4O4} complex of the formula C38H40Cl4Cu4N4O10 (1) showing photoluminescence properties. Complex 1 has been synthesised by the solvothermal reaction and characterized by element analysis, FT-IR, solid UV-Vis spectroscopy and single crystal X-ray diffraction. Crystal structural studies show that the Cu(II) centres in the tetrameric unit in complex 1 adopt distorted squarepyramidal geometries. The solid state photoluminescence properties of complex 1 and its ligand H2L have been investigated at room temperature in the visible region. When complex 1 and its ligand H2L are excited under UV light at 349 nm, complex 1 displays a strong violet emission at 452 nm and its ligand H2L displays green emission at 504 nm in the visible region. This promising luminescent behavior opens up possible applications for these compounds as sensing molecular devices or organic light emitting diodes (OLEDs).
