  Embodiments in accordance with the present invention encompass compositions encompassing a latent organo-ruthenium compound, a photosensitizer and 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 or a three dimensional object. Surprisingly, the compositions are very stable at ambient conditions to temperatures up to 80° C. for several weeks and undergo mass polymerization only when subjected to actinic radiation under inert atmosphere such as for example a blanket of nitrogen. 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、一种光敏剂和一种或多种单体，当所述组合物暴露在适当的光辐射下时，这些单体会发生开环偏聚聚合反应（ROMP），从而形成基本透明的薄膜或三维物体。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，可持续数周，并且只有在惰性气氛（例如氮气毯）下接受光辐射时才会发生大规模聚合。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、封装材料、填料、流平剂等。
