The preparation of the 3,6-disubstituted dibenzosilole monomers 4, 5 and 10 by two different routes is described; Suzuki copolymerisation afforded poly(9,9-dioctyl-3,6-dibenzosilole)
11 which has a sufficiently high triplet energy (2.55 eV) to function as a host for green electrophosphorescent emitters.
通过两种不同的路线制备了3,6-二取代二苯并硅杂芴单体4、5和10;铃木共聚反应得到了聚(9,9-二辛基-3,6-二苯并硅杂芴)11,其具有足够高的三重态能级(2.55 eV),可作为绿色电磷光发射体的主体材料。
