What is 1,1,2,3,4,5-Hexaphenylsilole?
The Uses of 1,1,2,3,4,5-Hexaphenylsilole
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.
General Description
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.
