Abstract
The dissertation discusses the synthesis of poly-aromatic hydrocarbons through electrophilic cyclization using ICl complex. We have succeeded in using this method to synthesize spiro[4,5]trienone as well as the phenanthrene derivatives. Under this foundation, we design a set of simple synthesis procedure to synthesize the dibenzo[g,p]crysene derivatives. This process requires a few steps and with excellent yields. We also investigated on the physical properties of these dibenzo[g,p]crysene derivatives, which includs UV, PL, CV, and quantum efficiency. We found the replacement of functional groups has shown effect on the physical features. Furthermore, this present work may focus on changing different functional groups, we could apply these materials in industries.
