Suzuki cross-coupling method to prepare 4,4″-diamino-p-terphenyl
Davis, Matthew C.
, p. 1343 - 1346 (2006)
The synthesis of 4,4″-dinitro-p-terphenyl is accomplished by double Suzuki cross-coupling. The product was reduced catalytically to give 4,4″-diamino-p-terphenyl in 75% overall yield. Copyright Taylor & Francis Group, LLC.

, (2020/09/26)
The present invention discloses a novel diamine having a structure including an intramolecular imide group while having an aromatic ring group with a rigid structure. In addition, and by comprising the novel diamine as a polymerization component, the present invention can provide a polyimide film having improved mechanical and thermal properties while maintaining optical properties of polyimide.
MECHANICALLY SHAPED 2-DIMENSIONAL COVALENT ORGANIC FRAMEWORKS

Covalent organic frameworks (COFs) usually crystallize as insoluble powders and their processing for suitable devices has been thought to be limited. Here, it is demonstrated that COFs can be mechanically pressed into shaped objects having anisotropic ordering with preferred orientation between the hk0 and 00/ crystallographic planes. Pellets prepared from bulk COF powders impregnated with LiC1O4 displayed room temperature conductivity up to 0.26 mS cm-1 and stability up to 10.0 V (vs. Li+/Li0). This outcome portends use of COFs as solid-state electrolytes in batteries.
