Abstract:
This invention relates to process for preparing fluorinated dyes selected from the group consisting of compounds of the general formulae (I) and (III) and mixtures thereof by reacting the corresponding compounds which do not have R12 or R30 as substituents with compounds of the general formula R12A or R30A where A is selected from the group consisting of I and Br, the compounds obtained from said process and and the use of these fluorinated dyes in electrophoretic displays.
Abstract:
The present invention provides the compounds of formulae ( 3 ) and (1), wherein n is 0 or 1, R11 and R12 are the same and are selected from the group consisting of CN, OR300, Si(R301)3, NHR302, NR303R304, SR305 and R306, or R11 and R12 together are selected from the group consisting of (a), (b), and (c) and X is Cl, Br or I, and a process for the preparation of compounds of formula (3) comprising the compounds of formula (1) as key intermediates.
Abstract:
The invention relates to a method for producing compounds of general formula (I) by converting the compound of general formula (II), where L, L' independently of one another are the same or different and represent Cl or OH, in the presence of a) chlorine compounds Cl-M2 R1 R2 R3, Cl-M3 R4 R5 R6, with the proviso that both L and L' are not OH at the same time, or b) hydroxy compounds HO-M2 R1 R2 R3, HO-M3 R4 R5 R6. The invention also relates to the use of compounds of general formula (I) as tracer substances for liquids and to methods for detecting tracer substances in liquids
Abstract:
The present invention relates to metal-carbene complexes comprising a central atom selected from iridium and platinum, and specific azabenzimidazolocarbeneligands, to OLEDs (Organic Light Emitting Diode, OLED)which comprise such complexes, to a device selected from the group consisting of illuminating elements, stationary visual display units and mobile visual display units comprising such an OLED,to the use of such a metal-carbene complex in OLEDs, for example as emitter, matrix material, charge transport material and/or charge or exciton blocker.
