  Polymeric Phosphine Ligand from Ring-Opening Metathesis Polymerization of a Norbornene Derivative. Applications in the Heck, Sonogashira, and Negishi Reactions

  摘要：

  The phosphine-containing polymer 1 is obtained by ruthenium-catalyzed ring-opening metathesis polymerization of the norbornene derivative 2. Polymer 1 is employed as the polymer support in the palladium-catalyzed Heck, Sonogashira, and Negishi reactions, and the corresponding (methoxymethylphenyl)diphenylphosphine (6) ligand is used for comparison. The polymer-supported catalysts retain most of their catalytic activities in these coupling reactions in the recycling processes.

  The present invention relates to methods of metathesizing olefins using catalysts previously considered to be practically inactive. The present invention further relates to novel photosensitive compositions, their use as photoresists, and methods related to patterning polymer layers on substrates. Further, modifications to the compositions and method provide for an unprecedented functionalization of the compositions, useful for example in the preparation of sensors, drug delivery systems, and tissue scaffolds. The novel compositions and associated methods also provide for the opportunity to prepare 3-dimensional objects which provide new access to critically dimensioned devices, including for example photonic devices.

  本发明涉及使用以前被认为实际上没有活性的催化剂对烯烃进行偏聚的方法。本发明还涉及新型光敏组合物、其作为光致抗蚀剂的用途以及在基底上形成聚合物层的相关方法。此外，对这些组合物和方法的改良为组合物的功能化提供了前所未有的可能性，例如在制备传感器、给药系统和组织支架时非常有用。新颖的组合物和相关方法还为制备三维物体提供了机会，从而为包括光子装置在内的关键尺寸装置提供了新的途径。

  The present disclosure is directed to photosensitive compositions ‘Fischer-type’ ruthenium carbene catalysts containing chelated 2,2′-bipyridine ligands and methods of using the same. These catalysts are surprisingly active even when using relatively low intensity diode light sources. The 2,2′-bipyridine-chelated ruthenium photocatalysts show reactivity at substantially lower exposure levels than other photoactive chelating dinitrogen ligands of similar structure. The present disclosure is further directed to novel photosensitive compositions, their use as photoresists, and methods related to patterning polymer layers on substrates.
