  Embodiments in accordance with the present invention encompass compositions encompassing a latent organo-ruthenium compound and a pyridine compound along with one or more monomers which undergo ring open metathesis polymerization (ROMP) when said composition is exposed to suitable actinic radiation to form a substantially transparent film. Surprisingly, the compositions are very stable at ambient conditions to temperatures up to 80° C. for several days and undergo mass polymerization when subject only to actinic radiation. Accordingly, compositions of this invention are useful in various opto-electronic applications, including as 3D printing materials, coatings, encapsulants, fillers, leveling agents, among others.

  根据本发明的实施方案，本发明的组合物包括一种潜在的有机钌化合物和一种吡啶化合物，以及一种或多种单体，当所述组合物暴露于适当的光辐射下形成基本透明的薄膜时，这些单体会发生开环偏聚（ROMP）。令人惊奇的是，这种组合物在环境条件下非常稳定，温度最高可达 80 摄氏度，可持续数天，而且仅在光辐射下就会发生大规模聚合。因此，本发明的组合物可用于各种光电子应用，包括用作 3D 打印材料、涂层、封装剂、填料、流平剂等。
