Fluoreszenz und Fluoreszenz‐Thermochromie bei Alkyl‐pyridinokupfer(I)‐Halogeniden

Abstract: Durch Zugabe von Acetylhalogenid zu Lösungen von Kupfer(I)‐acetat in Acetonitril/Essigsäuregemischen sind reinste Kupfer(I)‐Halogenide darstellbar. Diese bilden mit Pyridin und Alkylpyridinen (= L) gelbe bis grüngelbe Verbindungen der Zusammensetzung Cu(L)3X. Durch thermische Zersetzung können daraus farblose Verbindungen der Zusammensetzung Cu(L)X dargestellt werden. Alle diese Verbindungen zeigen eine intensive Fluoreszenz der verschiedensten Farben. Einige Verbindungen der Zusammensetzung Cu(L)X ändern bei … Show more

“…For example, copper(I) halidess upported by pyridines and phosphines have been reported to display photoluminescence. [54][55][56][57][58][59][60] In view of increasing importance of emissive materials in relation with devices, sensors, and artificial photosynthesis, studies on luminescent copper(I) complexes have been extended to those stabilized by diversified organic ligandsc ontaining nitrogen, phosphorus, carbon, and sulfur donor atoms. [61,62] Cu I -Cu I interactions have also been proposed to be involved in superconductivity in ceramic coppero xide superconductors according to an electron diffraction study of Cu 2 O.…”

“…It, however, should be noted that cuprophilic interactions have been implicated to play important roles in unexpected photophysical properties and conductivity of copper(I) compounds. For example, copper(I) halides supported by pyridines and phosphines have been reported to display photoluminescence . In view of increasing importance of emissive materials in relation with devices, sensors, and artificial photosynthesis, studies on luminescent copper(I) complexes have been extended to those stabilized by diversified organic ligands containing nitrogen, phosphorus, carbon, and sulfur donor atoms .…”

“…The molecular structures of 1 and 2 show that the bis(imino) fragment exhibits the (Z,E)-configuration as some other Ar-BIAN compounds, [18,43] instead of the more common (E,E)-configuration. [44][45][46][47] Compound 1, with a nitro substituent in the paraposition, presents a more planar bis(imino)acenaphthene skeleton than the non-substituted 2,4,6-Me 3 C 6 H 2 -BIAN, 5, as evidenced by the N(1)-C( 29 16) Å), but overall they are comparable with those observed in other Ar-BIAN compounds. [4][5][6][7]47] The breaking of symmetry of the NO 2 substituents seems to disfavour the (E,E) configuration observed when there is symmetry.…”

“…In einer vorausgehenden Arbeit berichteten De Ahna und Hardt über die Synthese der Komplexe CuX L mit X = Cl, Br, I und L = alkylierte Pyridine [17], Im Rahmen unserer Untersuchungen konnten wir ebenfalls Verbindungen der Zusammensetzung Cui · L (L = pic, 2,4-lut, 2,6-lut) erhalten, indem wir eine gesättigte Lösung von Cui in Acetonitril mit einem geringen Überschuß der Base, gelöst in Ethanol, umsetzten. Nach unseren Beobachtungen ist es jedoch erforderlich, daß bei der Darstellung die Temperatur nicht über 20 C ansteigt.…”

“…Außerdem existiert im System Cul/Picolin noch eine gelb lumineszierende Phase (/"", = 16500 cm" '), deren Bildungsweise und Zusammensetzung noch ungeklärt sind. De Ahna und Hardt [17] berichteten hingegen von einer ockerfarbenen Lumineszenz des Cui -pic. Es kann angenommen werden, daß diese Autoren kein reines Produkt vorliegen hatten.…”
