2-Bromo-9,9'-spirobi[9H-fluorene] Chemical Properties,Uses,Production

Application

2-Bromo-9,9'-spirodifluorene can be used as a pharmaceutical intermediate and is also an important intermediate for the synthesis of optoelectronic materials. It can be used in laboratory research and development processes as well as in chemical and pharmaceutical research and development.

Description

2-Bromo-9, 9’-spirobifluorene is a derivative of 9,9'-spirobifluorene. It is a quite useful blue light emitting material used in the organic light emitting diodes (OLEDs). It possesses high photoluminescence efficiency and good chemical stability. Moreover, It has high glass-transition temperature, excellent thermal stability and easy color tenability through introducing low band gap co-monomers.

Chemical Properties

Off-white to light yellow crystal or powder

Synthesis

Synthesis of 2-bromo-spirofluorene
2-bromo-9-hydroxy-9-(2-biphenyl)fluorene (2g) dissolved in 25 mL acetic acid (15 mol/L) containing hydrochloric acid (12 mol/L) was refluxed for about 2 h to separate out a white solid, which was recrystallized with ethanol to produce white crystals of 2-bromo-spirofluorene (1.2 g, yield 63%).
GC-MS (m/z +): 394. 1HNMR (400 MHz, CDCl3, ppm):δ7.80～7.86 (m, 3H), δ7. 70 (d, 1H),δ7.48 (m, 1H), δ7.36 ～ 7.40 (m, 3H), δ7.13 (m, 3H), δ6.84 (d, 1H), δ6.72 (m, 3H)
