Usage

General Description

2'-BroMo-2,7-di-tert-butyl-9,9'-spirobi[fluorene] is a chemical compound consisting of a spirobi[fluorene] core with two tert-butyl groups attached to the 2 and 7 positions and a bromine atom at the 2' position. 2'-broMo-2,7-di-tert-butyl-9,9'-spirobi[fluorene] is often used as a building block in organic synthesis and materials science due to its unique spirobi[fluorene] structure. It has been studied for its potential use in organic light-emitting diodes (OLEDs) and other optoelectronic devices. The tert-butyl groups provide steric hindrance, making the molecule bulky and hindering intermolecular interactions, which can be advantageous for certain applications. The bromine atom can also be utilized for further functionalization of the molecule.
