9-bromo-2-fluoro-9H-fluorene is a halogenated aromatic compound characterized by the presence of a bromine atom at the 9th position and a fluorine atom at the 2nd position on the fluorene core. Fluorene itself is a polycyclic aromatic hydrocarbon with a structure consisting of two fused benzene rings. The introduction of halogen atoms, such as bromine and fluorine, into the fluorene molecule can significantly alter its chemical and physical properties, making it suitable for various applications in the fields of materials science, pharmaceuticals, and organic synthesis. The unique combination of electron-withdrawing fluorine and electron-donating bromine atoms in 9-bromo-2-fluoro-9H-fluorene can lead to interesting reactivity patterns and potential uses in the development of new compounds and materials.

6344-64-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6344-64-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,3,4 and 4 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 6344-64:
(6*6)+(5*3)+(4*4)+(3*4)+(2*6)+(1*4)=95
95 % 10 = 5
So 6344-64-5 is a valid CAS Registry Number.

Studies of fluorine auxochrome in C9-fluorenyl anthracenes on optoelectronic property for blue electroluminescent materials

Ma, Guobin,Zhao, Huaxin,Wang, Jing,Le, Yuping,Jiang, Haizhen,Deng, Hongmei,Hao, Jian,Wan, Wen

, p. 420 - 427 (2018/06/14)

Two series of fluorine-containing fluorenyl anthracenes linked by a rigid sp3-hybridized carbon atom have been synthesized and characterized. The effect of a fluorine auxochrome at different positions in fluorene moiety on bulk properties, such as photophysical, electrochemical properties and thermal stabilities were investigated. The non-doped organic light-emitting diodes (OLEDs) utilizing C9-methylated fluorinated fluorenyl anthracene 4b as the emitter exhibits deep-blue emissions CIE x, y (0.159, 0.106) with efficiency of 1.31 cd/A and a maximum brightness of 2040 cd/m2 at 14 V. It was found that the introduction of fluorine auxochrome to the C2 position of fluorene could afford the best performances of OLEDs among the fluorinated materials.
