Polyanionic Aryl Ether Metallodendrimers Based on Cobaltabisdicarbollide Derivatives. Photoluminescent Properties

E. J. Juárez-Pérez, C. Viñas, F. Teixidor, R. Santillan, N. Farfán, A. Abreu, R. Yépez and R. Núñez* Macromolecules, 2010, 43 (1), pp 150–159 Fluorescent Fréchet-type poly(aryl ether) dendrimers that incorporate the 1,3,5-triphenylbenzene as core molecule and 3, 6, 9, or 12 terminal allyl ether groups have been prepared in very good yield by following the Fr echet convergent approach. Regiospecific hydrosylilation reactions on the allyl ether functions with the cobaltabisdicarbollide derivative Cs[1,10-μ-SiMeH-3,30-Co(1,2-C2B9H10)2] lead to different generations of Fréchet-type polyanioic metallodendrimers decorated with 3, 6, and 9 cobaltabisdicarbollide units. Starting dendrimers exhibit photoluminescence properties at room temperature under ultraviolet irradiation; nevertheless, after functionalization with cobaltabisdicarbollide derivatives, the fluorescence properties are quenched. Products are fully characterized by FTIR, NMR, and UV-vis spectroscopies. For metallodendrimers, the UV-vis absorptions have been a good tool for estimating the experimental number of cobaltabisdicarbollide units peripherally attached to the dendrimeric structure and consequently to corroborate the unified character of the dendrimers. Because of the anionic character of these compounds and the boron-rich content, we actually focus our research on biocompatibility studies and potential applications.

In search of an optimized electrolyte for Na-ion batteries

Electrolytes are essential for the proper functioning of any battery technology and the emerging Na-ion technology is no exception. Hence, a major focus on battery research is to identify the most appropriate formulation so as to minimize interface reactions and enhance both cell performances and safety aspects. In order to identify suitable electrolyte formulations for Na-ion chemistry we benchmarked various electrolytes containing diverse solvent mixtures (cyclic, acyclic carbonates, glymes) and Na-based salts having either F-based or perchlorate anions and measured viscosity, ionic conductivity, and thermal and electrochemical stability. The binary EC:PC solvent mixture has emerged as the best solvent formulation and has been used to test the performance of Na/hard carbon cells with both NaClO4 and NaPF6 as dissolved salts. Hard carbon electrodes having reversible capacities of 200 mA h g−1 with decent rate capability and excellent capacity retention (>180 cycles) were demonstrated. Moreover, DSC heating curves demonstrated that fully sodiated hard carbon cycled in NaPF6–EC:PC exhibits the highest exothermic onset temperature and nearly the lowest enthalpy of reaction, thus making this electrolyte most attractive for the development of Na-ion batteries.

NANOMOL, finalist of the second conquest VALORTEC

The research group NANOMOL from the Materials Science Institute of Barcelona (ICMAB-CSIC), the CIBER-BBN and TECNIO catalan Network, has been selected finalist of the second edition of the contest VALORTEC of ACC1Ó in the "Innovative Technology-Based Companies category", thanks to the project Medical Sensors.

In this first stage of the contest a total of 102 applications have been submitted, from which the jury has selected only 10 as finalists in each category.

The Medical Sensors project is based on the use of organic materials for the manufacture of pressure, deformation and temperature sensors of high performance and aims to transform the prototypes developed by the Research Group NANOMOL into commercial products in the area of medical devices, with ability to provide clinical professionals with an innovative tool for patient monitoring.

During the month of December there will be the second phase of the process through delivery, presentation and evaluation of business plans developed. Winners will receive a € 10,000 first prize and a second of 5,000 €.
