摘要:对于具有成本效益的有机电子设备,通过基于溶液的工艺连续沉积有源层是一个关键优势.我们报告了一种合成方法,该方法能够降低双(环戊二烯基)取代的聚芴作为有机发光二极管(oled)中的发光层的溶解度.热诱导的逆diels-Alder反应释放出游离的环戊二烯作为"保护基"和未决的环戊二烯基单元,这些单元通过[4 + 2]环加成反应冷却后可将聚合物链交联.通过烷基,烷氧基或酯键,可以将活化温度调节在180-250oc的范围内.最终,大环自我保护的双(环戊二烯)部分避免了活化过程中挥发性环戊二烯的挤出.通过吸收光谱法和白光扫描干涉法检查交联后的发光层的耐溶剂性.研究了增溶过程对溶液加工的oled性能的影响.

摘要:This invention relates to compositions and methods for improving the adhesion of resin compositions to substrate materials, pre-treating substrate materials to improve the adhesion of resin compositions to the substrate materials, and/or controlling gel formation of resin compositions. More particularly, the invention relates to compositions and methods for improving the adhesion of ring opening metathesis polymerization (ROMP) compositions to substrate materials using adhesion promoters containing isocyanate groups in a resin composition. The invention also relates to methods for improving the adhesion of resin compositions to substrate materials by pre-treating substrate materials with adhesion promoters containing isocyanate groups. The invention further relates to a method of providing a gel-modified ROMP composition, in which a hydroperoxide is added to a ROMP polymerizable resin composition in order to control gel formation of the polymerizing resin. An improved ROMP composition is further disclosed, comprising a cyclic olefin, a ROMP metathesis catalyst, an adhesion promoter, and an added hydroperoxide gel modifier. The polymer products produced via ROMP reactions of the invention may be utilized for a wide range of materials and composite applications. The invention has utility in the fields of catalysis, organic synthesis, and polymer and materials chemistry and manufacture.
