Formula: C12H8Br2. Published in PERGAMON-ELSEVIER SCIENCE LTD in OXFORD ,Authors: He, YQ; Tang, JH; Li, ZQ; Zhong, YW. The CAS is 92-86-4. Through research, I have a further understanding and discovery of 4,4′-Dibromobiphenyl
The synthesis of 7-conjugated organic materials through C-H activation and functionalization has recently received increasing attention. In this work, four pyrid-2-yl-appended para-phenylene oligomers (1-4) with two to five phenyl repeating units were synthesized via the Ru-catalyzed C-H activation of 2-phenylpyridine, followed by oxidative homocoupling or the arylation with a para-phenylene dibromide substrate. The single-crystal X-ray data and crystal packing of 1 and 3 are presented. In response to acid stimuli, the blue emissions of 1-3 are replaced by red-shifted cyan emissions, which are associated with the charge transfer transition from the phenylene backbone to the protonated pyridinium units. However, the emission of the longest congener 4 is largely quenched upon protonation. This lengthdependent emission property is rationalized by DFT and TDDFT calculations. (C) 2020 Elsevier Ltd.
