Patent CA-2494920-A1 (CA)
Inventor: PETERS ANDREA
IPC: C09K9/02
Filed: 2003-08-11
Abstract: This invention relates to novel photochromic and electrochromic monomers and polymers based on 1,2-dithienylcyclopentene derivatives and method of using and synthesizing same. The compounds are reversibly interconvertible between different isomeric forms under suitable photochromic or electrochromic conditions. The electrochromic conversion may be catalytic. The application also relates to ultra-high density homopolymers prepared using ring-opening methathesis polymerization (ROMP) where the central ring of the 1,2-bis(3-thienyl)-cyclopentene is incorporated directly into the polymer backbone. The monomer units may be readily functionalized to enable the synthesis of polymers with diverse structural and electronic properties. The compounds have many potential applications including high-density optical information storage systems, photoregulated molecular switches, reversible holographic systems, ophthalmic lenses, actinometry and molecular sensors, photochromic inks, paints and fibers and optoelectronic systems such as optical waveguides, Bragg reflectors and dielectric mirrors.

Abstract: L'invention concerne un procédé pour créer des couches d'absorption d'UV sur un substrat organique ou inorganique. L'invention est caractérisée en ce que a) on fait agir un plasma basse température, une décharge couronne ou un rayonnement riche en énergie sur le substrat organique ou inorganique, b) on met sur le substrat organique ou inorganique traité au moins un amorceur formant des radicaux et au moins un absorbeur d'UV contenant au moins une groupe éthyléniquement insaturé, et, éventuellement sous forme de matières fondues, de solutions, de suspensions ou d'émulsions, au moins un agent synergiste et/ou un composé éthyléniquement insaturé, c) on chauffe le substrat enduit et/ou on l'irradie d'ondes électromagnétiques. La présente invention porte également sur un substrat doté d'une couche d'absorption d'UV selon ledit procédé. Ce procédé exclut la plupart du temps des conditions de vide et une sollicitation énergétique ou thermique trop importante, ainsi que la destruction de l'absorbeur d'UV. Cette invention permet de réaliser des couches d'absorption d'UV transparentes et de bonne adhérence, dont les propriétés sont avantageusement modulables comme, par exemple, la densité optique.

Title: Method for producing orthometalated and orthosubstituted metallocences
Inventor: LOTZ MATTHIAS
IPC: C07F9/6584
Filed: 2004-12-10
Abstract: The invention relates to compounds having a structural element of formula (I) in an aromatic hydrocarbon ring, wherein: M represents -Li, -MgX3, (C1-C18-Alkyl)3Sn-, -ZnX3 or -B(O-C1-C4-Alkyl)2; X1 and X2, independent of one another, represent O or N, and C-bound hydrocarbon radicals or heterohydrocarbon radicals are bound to the free bonds of the O and N atoms;  group -C=C-, together with C atoms, forms a hydrocarbon aromatic compound and represents X3 Cl, Br or I. The inventive compounds are easily obtained by directly substituting the hydrogen in the ortho position to the P atom with metalation reagents. The metal atoms can then be substituted by a reactive electrophilic compound. The group -P(X1-)(X2-)----(BH3)0,1 can then be converted into a secondary phosphine group. The inventive method enables the production of monophosphines and diphosphines even on a large scale, which are valuable ligands for metal complexes serving as catalysts for, e.g.  enantioselective hydrogenations.
