Synthesis and properties of σ‐π conjugated porous polymers obtained with Mizoroki–Heck reaction of tetra vinyl cyclic siloxane with dibromo fluorene

σ‐π Conjugated porous polymers were synthesized by the Mizoroki–Heck reaction of cyclic siloxane with vinyl groups, 1,3,5,7‐tetravinyltetramethylcyclotetrasiloxane (TVMCTS), and 2,7‐dibromo‐9,9‐dialkylfluorene (RFl) compounds, using a Pd catalyst in N , N ‐dimethylformamide (DMF) at 100°C. The reactions of TVMCTS in combination with 2,7‐dibromo‐9,9‐dihexylfluorene (HFl), 2,7‐dibromo‐9,9‐dioctylfluorene (OFl), and...
