将[Ln(BH4)(3)(THF)(3)] （Ln = La, Nd）接枝到二氧化硅上，可以得到含有良好识别的双（硼氢化物）表面物质的材料。钕修饰二氧化硅将-丁内酯单体转化为高度等规聚（-羟基丁酸酯）。在类似的条件下，分子前体产生无规聚合物。
Grafting of [Ln(BH4)(3)(THF)(3)] (Ln = La, Nd) onto silica affords materials containing well-identified bis(borohydride) surface species. The neodymium-decorated silica converts the beta-butyrolactone monomer into highly isotactic poly(beta-hydroxybutyrate). Under similar conditions, the molecular precursor gives rise to an atactic polymer.
