Application

4-Vinylphenylboronic acid is commonly used in the synthesis of styrene-based organoboron polymers such as vinyl-oligo(fluorene) polymer and boronic ester based self-healing polymer. It can also be used as a precursor in the synthesis of aggregation induced emission (AIE) dye.

Synthesis of 1,3,5,7-tetranitro-1,3,5,7-tetraazacyclooctane and 1,3,5-trinitro-1,3,5-triazacyclohexane by the Bachmann process leads to a mixture of both. The separation of 1,3,5,7-tetranitro-1,3,5,7-tetraazacyclooctane and 1,3,5-trinitro-1,3,5-triazacyclohexane from their mixture is difficult because the sizes and physical properties of these homologous compounds are similar. For this
