Hexaphenylsilacyclopentadiene may undergo π⁴s+π²s cycloaddition with ethyl acrylate to form bicyclosilaheptene. The same study reports similar cycloaddition reactions with various dienophiles. The reaction of hexaphenylsilacyclopentadiene with perbenzoic acid yields a mixture of tetraphenylfuran and cis-dibenzoylstilbene.

HPS is an aggregation-induced emission (AIE) material for use in the OLED emitting layer. Photolysis and thermolysis of 1,4,5,6,7,7-hexaphenyl-7-silabicyclo[2.2.1]hept-5-ene-2,3-dicarboxylic anhydride (XIb) may lead to the formation of hexaphenylsilacyclopentadiene.
