Paragraph 0114-0116, (2020/07/12)
The invention relates to the technical field of electric control fluorescence, and provides a diamine compound containing a bis(diphenylamine)-tetraphenyl ethylene structure. The diamine compound hasa structure shown as formula I, the diamine compound provided by the invention has a "2, 2-triphenylamine-tetraphenyl ethylene" structure, in polyamide prepared from the diamine compound, a tetraphenyl ethylene group with an aggregation-induced emission effect endows polyamide with the excellent characteristic of bright fluorescence in a solid state, and enables polyamide to have a high fluorescence quantum yield; meanwhile, star-shaped tetraphenyl ethylene and triphenylamine structures in the polyamide can weaken close packing of a polyamide molecular chain and improve the ion doping rate, sothat the electric control fluorescence response time of the polymer is shortened; besides, an electron donating group is introduced into the para-position of triphenylamine, so that the oxidation potential can be effectively reduced, and the electrochemical stability of polyamide is improved.

A series of novel cis-furoquinoline derivatives was synthesized and tested for their antitumor activities in vitro against HepG2 cells, Lu-04 cells and Leu02 cells to evaluate structure-activity relationships. Assay-based antiproliferative activity study revealed that several compounds had significant effects on cytotoxicity, among which compounds 2f, 2l, 2q were found to be the most active compounds. Above all, compounds 2f, 2l, 2q would be potential anticancer agents which deserved further research.

A variety of substituted anilines are selectively oxidized to afford high yields of azoxyarenes by using 30% hydrogen peroxide and selenium dioxide as catalyst in methanol at room temperature. The oxidation of 4-alkoxyanilines under the same reaction conditions furnishes the corresponding 4-alkoxy-N-(4-nitrophenyl)anilines in reasonable yields, alongside other oxidation byproducts. The structure of 4-methoxy-N-(4-nitrophenyl)aniline is elucidated by X-ray crystal structure analysis. From these results, some general aspects of the reaction pathways of aniline oxidation are discussed.
