  1. Exploratory research project, funded by CNCSIS, program PN II ‘Idei’ Contract no. 506/14.01.2009 LUMINESCENT MOLECULAR MATERIALS OBTAINED BY SELF-ASSEMBLY PROCESSES Director: Dr. Gabriela MARINESCU Lenght: 14.01.2009 – 30.11.2011

  2. Summary The present research proposal develops a systematic study of the synthesis and photophysical properties of metal-supramolecular systems obtained by using each of following luminescent species or their combination: a) complexes built with Zn(II), Cd(II) ions (d10 electronic configuration) and Schiff base compartmental ligands, the luminescence being generated mainly by the organic backbone; b) lanthanide(III) containing complexes [4f luminescent ions in the visible – Tb(III), Eu(III), or near infrared region – Pr(III), Nd(III), Er(III), Yb(III)]; c) supramolecular syntons built on metalophilic interactions (d8- d8, d10 - d10). The major goals of the proposal are to build luminescent crystalline metal organic networks containing three different luminescent species (combination of d10, 4f chromophores and d8-d8, d10-d10 metalophilic interactions) and, also, to synthesize chiral-luminescent homo- and heterometallic systems by the self-assembly of metal units with chiral organic linkers, in order to get multifunctional systems through the combination of two properties (fluorescent and optical). The supramolecular systems will be characterized by X-ray single-crystal diffraction, various spectroscopic (IR, UV-VIS, NIR) and also special measurements according to their properties (fluorescence, magnetism). The rational combination of different properties opens the way to technical application of these systems.

  3. Objectives • Rational synthesis of luminescent supramolecular systems built on homo- and heterometallic tectons (d10-d10, d10-4f, 4f-4f and 4f-4f’) • Design of heterometallic supramolecular architectures by using two luminescence sources (d10 or 4f luminophores and d8-d8, d10-d10 metalophilic interactions) • Chiral-luminescent homo- and heterometallic systems by the self-assembly of metal units with chiral organic linkers • Luminescent crystalline metal organic networks containing three different luminescent species (combination of d10, 4f chromophores and d8-d8, d10-d10 metalophilic interactions). This would be the first time such a system is synthesized • Investigation of the luminescent properties of the newly synthesized molecular systems; magneto-structural correlations for the systems that contain paramagnetic metal ions (especially 4f ions).
