A series of chloride-bridged unsymmetrical mixed Fe(II)-HS/Fe(II)-LS binuclear structures has been prepared and characterized. Upon activation with MAO, highly efficient catalytic polymerization of isoprene was achieved, delivering an ultra-high molecular weight (catalyst loading = 2.5 ppm, M_n = 1.8 × 10⁶ g mol⁻¹, M_w/M_n = 1.4).

不对称双核亚氨基吡啶-铁配合物及其催化异戊二烯聚合。

制备并表征了一系列氯桥联的非对称Fe（II）-HS / Fe（II）-LS双核结构。通过MAO活化后，实现了异戊二烯的高效催化聚合，提供了超高分子量（催化剂负载量= 2.5 ppm，M _n = 1.8×10 ⁶ g mol ^-1，M _w / M _n = 1.4）。
