General description

2-Bromofluorene is a nonintrusive end-capping reagent to control molecular weights and to generate well-defined oligomers.

Application

2-Bromofluorene was used in the synthesis of end-capping reagent 2-bromo-9,9-di-nhexylfluorene. It has been used in the preparation of poly(di-n-hexylfluorene)s end capped with 2-bromofluorene, 2-bromo-9,9-di-n-hexylfluorene and 9-bromoanthracene through Ni(0) mediated polymerization. It was also used in the synthesis of 2-bromo-9,9-dihexylfluorene.
