Formula: C12H8Br2. I found the field of Chemistry very interesting. Saw the article [n]-Cyclo-9,9-dibutyl-2,7-fluorene (n=4, 5): Nanoring Size Influence in Carbon-Bridged Cyclo-para-phenylenes published in 2020, Reprint Addresses Poriel, C (corresponding author), Univ Rennes, CNRS, ISCR, UMR 6226, F-35000 Rennes, France.. The CAS is 92-86-4. Through research, I have a further understanding and discovery of 4,4′-Dibromobiphenyl.
For the last ten years, ring-shaped pi-conjugated macrocycles possessing radially directed pi-orbitals have been subject to intense research. The electronic properties of these rings are deeply dependent on their size. However, most studies involve the flagship family of nanorings: the cyclo-para-phenylenes. We report herein the synthesis and study of the first examples of cyclofluorenes possessing five constituting fluorene units. The structural, optical and electrochemical properties were elucidated by X-ray crystallography, UV-vis absorption and fluorescence spectroscopy, and cyclic voltammetry. By comparison with a shorter analogue, we show how the electronic properties of [5]-cyclofluorenes are drastically different from those of [4]-cyclofluorenes, highlighting the key role played by the ring size in the cyclofluorene family.
