Solid-state reactions of copper(i) iodide with 1,4-diazabicyclo[2.2.2] octane (DABCO) and piperazine in different conditions (kneading, vapour digestion, thermal treatment) resulted in the formation of four new luminescent systems, which have been characterized via X-ray diffraction and photo-luminescence spectroscopy.

Abstract
Solid-state reactions of copper(i) iodide with 1,4-diazabicyclo[2.2.2] octane (DABCO) and piperazine in different conditions (kneading, vapour digestion, thermal treatment) resulted in the formation of four new luminescent systems, which have been characterized via X-ray diffraction and photo-luminescence spectroscopy. At room temperature all compounds exhibit a bright emission in the solid state that markedly shifts bathochromically on cooling to 77 K. The luminescence of the almost isostructural 2D-coordination polymers [Cu2I2(L)2]∞ (L = DABCO, piperazine) exhibits an unusually long lifetime (125 and 53 μs, respectively), which becomes even longer (609 and 420 μs, respectively) at 77 K. © 2011 The Royal Society of Chemistry and the Centre National de la Recherche Scientifique.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
