摘要:
The present invention is directed to maleimides and preparation of compounds of the formula I wherein R1 and R2 independently from each other stand for variously substituted, and R3 stands for allyl, variously substituted, with the proviso, that R1 and R2 not simultaneously stand for phenyl.
摘要:
The present invention relates to methods for using a maleimide of formula (I) with the proviso that R1 and R2 do not simultaneously stand for phenyl or a maleimide of formula Ia as UV fluorescent material for void detection and for the preparation of scintillators films, luminescent solar energy collectors, organic electroluminescent devices, printing inks, non-impact printing inks, electrophotographic toners, color filters, and colored high molecular organic material.
摘要:
The present invention relates to compounds of formula I provided that R1 and R2 not simultaneously stand for phenyl, the use thereof in, for example, electroluminescent devices and as void detection compounds.
