Abstract
This dissertation is consisted of two main ideas. First, multi-fluoro substituted oligo-(phenylenevinylene) derivatives were used in the appli- cation of organic-light emitting devices (OLEDs) that showed deep blue light. Additionally, we also made an approach to molecular-design in order to tune the electroluminescence wavelength on our own wish. On the other side, cyclization of enediynes had attracted much attention owing to their applicable in the material and medicinal chemistry field. Therefore, we synthesized those enediyne substrates, and 5 mol% platinum dichloride acted as a catalyst under 100 oC oil bath in 3-pentanone solution. Afterward, the enediynes underwent an intra- molecular [3+2]-cyclization to afford the [3.3.0]-bicyclo adduct. Furthermore, methods described above could provide an atom- economical way to have the [3.3.0]-bicyclo products in hand.
