Polymerization-induced self-assembly (PISA) and crystallization-driven self-assembly (CDSA) are among the most prevailing methods for block copolymer self-assembly. Taking the merits of scalability of PISA and dimension control of CDSA, we report one-pot synchronous PISA and CDSA ring-opening metathesis polymerization (ROMP) to prepare nano-objects based on a crystalline poly(ruthenocene) motif. We denote this self-assembly methodology as ROMPI-CDSA to enable a simple, yet robust approach for the preparation of functional nanomaterials.

聚合诱导自组装（PISA）和结晶驱动自组装（CDSA）是嵌段共聚物自组装最常用的方法。结合PISA的可扩展性优点和CDSA的尺寸控制优点，我们报道了一锅法同步进行PISA和CDSA的开环易位聚合（ROMP），以制备基于结晶聚（钌茂）基序的纳米物体。我们将这种自组装方法称为ROMPI-CDSA，从而为制备功能纳米材料提供一种简单而稳健的方法。
