New β-oxime ester biphenyl compounds, photoinitiators containing them and photosensitive resin compositions

The present invention relates to a novel andbeta;-oxime ester biphenyl compound, and a photoinitiator and a photosensitive resin composition containing the same. The problem to be solved in the present invention is to provide an initiator which does not generate yellowing under heat-resistant conditions since the initiator has excellent radical generation efficiency with a small exposure amount.COPYRIGHT KIPO 2020

Use for RL intermediate condensation product synthesis process (by machine translation)

The present invention discloses a use for RL intermediate condensation product synthesis process, the process comprises the steps of: carbazole alkylation N - ethyl carbazole made, by nitration, reduction to generate a 3 - amino - N - ethyl carbazole, then in the organic solvent in the condensation reaction, use for intermediate condensate obtained RL; in this invention the condensation reaction using an alcohol as a solvent to replace the traditional O-chlorobenzene, improves the 3 - amino - N - ethyl carbazole conversion rate, and improves the use for RL crude purity and yield, and the process is stable, simple operation, high safety factor.

Novel Schiff base compound taking triphenylamine as center and preparation of novel Schiff base compound

The invention provides a novel Schiff base compound taking triphenylamine as a center and having a structural formula I, and a preparation method of the novel Schiff base compound. The preparation method comprises steps of: reacting triphenylamine with DMF and POCl3 to prepare 4,4-diformyltriphenylamine; preparing N-ethylcarbazole from carbazole and bromoethane; nitrifying N-ethylcarbazole to obtain 3-nitro-N-ethylcarbazole; further reducing nitro to obtain 3-amino-N-ethylcarbazole; and finally reacting 4,4-diformyltriphenylamine with 3-nitro-N-ethylcarbazole to obtain the Schiff base compound. The prepared Schiff base compound has carbon-nitrogen double bonds (C=N) and a relatively large pi electron delocalization skeleton, which provides the compound with a relatively large fluorescence absorption coefficient. Due to the presence of lone pair electrons of C=N, the novel Schiff base compound has a potential application to detection of metal ions.
