- Development of ruthenium complexes with ammines as ancillary ligands for homogeneous catalysis of ring opening metathesis polymerization of cyclic olefins, AP.R
Abstract
Ruthenium complexes with cyclic and acyclic amines will be developed to act as catalysts in reactions of ring-opening metathesis polymerization (ROMP). In addition to the ammines in the metal coordination sphere, phosphines, phosphites or sulfoxides will also be present as ancillary ligands. The strategy is to make electronic and steric hindrance combinations by using different ancillar...
- Synthesis of ruthenium complexes a coordinated Schiff Bases for application in polymerization via olefin metathesis, BP.IC
Abstract
The catalytic reactivity of complexes of the type [ RuCl2 ( PPh3 ) x ( BS ) ] , where BS is the type Schiff Bases will be studied ¬ R 'N = CHPh , R ' = 2,6- diethylphenyl or sec - butyl , in polymerization reactions via ring-opening metathesis ( ROMP ) of norbornene (NBE ), and norbonadieno ( NBD ) . The BS will be obtained by reaction between salicylaldehyde and the corresponding amine...
- Synthesis of functionalized Metal-monomers of Barrelene with Polipyridines of Ru(II) to obtaining polymeric sensitizers via ROMP, BP.DR
Abstract
In this work is proposed the synthesis of ruthenium bipyridine-based metalopolymers from barrelene units, which will be synthesized in four steps. Once synthesized the barrelene, it will be functionalized with phenanthrene to increase the absorption of light with its conjugate chain, besides the bipyridine, that is able to coordinate to the metal ruthenium and to produce a photoactive c...
- Ring opening metathesis polymerization of cyclic olefins catalyzed by a ruthenium complex immobilized on carbon nanotube, BP.MS
Abstract
The project aims toimmobilize the complex [RuCl2 (PPh3) 3] in the array of carbon nanotube (CNT), ín a way that it is employed in reactions of ROMP (ring opening metathesis polymerization). The reactions will be tested with norbornene and norbornadiene in solutions of CHCl3 at room temperature and 50 ° C, on time intervals from 5 to 60 min and compared with systems in homogeneous phase....

- Correlation between the properties of the polymers and biopolymers obtained by ROMP with [RuCl2(PPh3)2(amine)] complex types, BE.EP.DD
Abstract
It is planned to characterize polymers obtained from ROMP reactions using catalyst precursors developed in the current PhD project. This require came from initial observations collected by DSC, TGA and SEM of the obtained polymers, as described in the 1st annual report (jan-dec 2012). The monomers under investigation to prepare the polymers are norbornene (NBE), norbornadiene (NBD) and ...
