The Mizoroki‐Heck reaction of cyclic siloxane with vinyl groups, 1,3,5,7‐tetravinyltetramethylcyclotetrasiloxane (TVMCTS), and 2,7‐dibromo‐9,9‐dialkylfluorene, using a Pd catalyst (Pd(OAc)₂) in N,N‐dimethylformamide (DMF) successfully yielded σ‐π conjugated porous polymers induced by phase separation during the network formation. The polymerization conditions affected the morphology of the porous structure with connected globules and/or isolated‐deformed holes. Naofumi Naga and colleagues on page 2301 explain that the porous polymers show emission derived from σ‐π conjugated fluorene with high quantum yields. (DOI: 10.1002/pol.20200268)

环硅氧烷与乙烯基，1,3,5,7-四乙烯基四甲基环四硅氧烷（TVMCTS）和2,7-二溴-9,9-二烷基芴的Mizoroki-Heck反应，使用Pd催化剂（Pd（OAc）₂）在N，N-二甲基甲酰胺（DMF）在网络形成过程中通过相分离成功产生了σ-π共轭多孔聚合物。聚合条件影响了带有连接小球和/或孤立变形孔的多孔结构的形态。Naofumi Naga及其同事在第2301页上解释说，多孔聚合物显示出具有高量子产率的，由σ-π共轭芴衍生的发射。（DOI：10.1002 / pol.20200268）
