5. Improving the Electroluminescence of [Zn(salophen)(OH2)] in Polyfluorene-Based Light-Emitting Diode: The Role of Energy Transfer and Charge Recombination
Combining two or more different compounds with advantageous properties has been a useful and straightforward strategy in achieving a new class of materials with improved physical properties. This has been especially true for electronic polymers, whose optoelectronic properties can be completely tuned, and even improved, when mixed with other polymeric materi

6. Catalytic Activity of a Titanium(IV)/Iron(II) Heterometallic Alkoxide in the Ring‑Opening Polymerization of ε-Caprolactone and rac-Lactide
The activity of the heterometallic alkoxide [FeCl{Ti2(OiPr)9}] (1) towards polymerization of rac-lactide (rac-LA) and ε-caprolactone (ε-CL) was investigated in toluene solution and in bulk at various temperatures, monomer/heterometallic alkoxide molar ratio and reaction times. The alkoxide 1 was active in solution for ε-CL and in bulk for both monomers. P

7. Synthesis and Structural Analysis of Binary and Ternary Clusters Derivatives from Mercury Bis(phenylselenolate) - Hg(SePh)2 / Síntese e Análise Estrutural de Clusters Binários e Ternários Derivados de Bis(fenilselenolato) de Mercúrio Hg(SePh)2
This work deals with the synthesis and structural analysis of binary and ternary clusters derivatives from mercury bis(phenylselenolate) - Hg(SePh)2. The reaction of Hg(SePh)2 with Mg(II), Fe(II), Co(II) and Ni(II) metal salts led to the formation of a series of binary clusters [M(DPPMO2)3][Hg4X4(SePh)6]4DMFH2O and [M(DMF)6][Hg8SeX4(SePh)12]. The reaction of
