Boron‐ and silicon‐containing conjugated homo‐ and copolymers could be synthesized using acyclic diene metathesis (ADMET) condensation of bis‐styryl monomers. Both, tri‐and tetra‐coordinated boron monomers were successfully polymerized forming homopolymers, or random copolymers (if polymerized together with a silicon containing co‐monomer). Polymer molecular weights Mn were measured at ∼6000 to 15
可以使用双苯乙烯单体的无环二烯复分解(ADMET)缩合合成含硼和硅的共轭均聚物和共聚物。三配位和四配位的硼单体均已成功聚合,形成均聚物或无规共聚物(如果与含硅共聚单体一起聚合)。测得的聚合物分子量M n为约6000至15,000 g / mol(NMR端基分析),分子量分布M w / M n为约1.8至2.2。该聚合物吸收在λ最大~317至406纳米,在发射的λ最大约370至494 nm,荧光量子效率约24至48%。具有三配位硼的共聚物在氟离子存在下以硼/氟化物〜5/1的比例显示出高效的荧光猝灭,证明了其作为阴离子传感器的潜力。©2015 Wiley Periodicals,Inc.
