HPS 是用于 OLED 发射层的聚集诱导发射（AIE）材料。1,4,5,6,7,7-六苯基-7-硅双环[2.2.1]庚-5-烯-2,3-二羧酸酐（XIb）的光解和热解可能导致六苯基硅环戊二烯的形成。 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.
