AI Technical Summary
Boron cluster anions have poor reactivity and regioselectivity, making their functionalization difficult. Furthermore, traditional polymerization methods make it difficult to precisely control the molecular weight and molecular weight distribution of polymers, resulting in poor uniformity of properties in boron cluster polymers and limiting their industrial application and functional expansion.
Boron clusters with end-functionalized boron clusters are introduced with alkynyl or norbornene groups through ring-opening reactions to improve their reactivity and selectivity. They are then combined with polymers through azidoyne-cycloaddition and ring-opening metathesis polymerization to prepare boron cluster polymers.
This improved the binding stability and performance uniformity of boron clusters with polymers, enhanced the thermal stability of boron cluster-containing polymers, and expanded their application prospects in the field of boron neutron capture therapy.
