Replace) Imide Synthesis And Properties Of The Research

Perylene dyes have found widespread applications ranging from industrialpigments to components of molecular photonic devices. As an important class offunctional materials, perylenebisimide derivatives possess many advantages of stablestructure, outstanding photoelectron properties, high thermal stability and exhibitwide absorption and emission bands in the visible region, which can be widely used inorganic solar cell, organic solid state photovoltaic device, organic thin-filmfield-effect transistor and so on. In this paper, we mainly study on the new methods ofthe modifying of perylenebisimides, which have important significance on thesynthesis of novel perylenebisimides. Four chapters were included in this article, andthe main contents of each chapter will be described in the followings.The research on synthesis of the perylenebisimide derivatives together withtheirproperties and applications have been reviewed in Chapter 1. Owing to thevarious applications synthesis of perylene derivatives is very important.This thesisaims to design and synthesize a series of novel perylene derivatives.Novel nitryl-substituent perylene derivatives were synthesizedsmoothly withhigh yield. The reactions of nitryl-substituent perylene derivatives with triethylphosphate were studied; the reason was discussed by theoretical calculation.The reactions of nitryl-substituent perylene derivatives were studied, some novelreactions were found compared to general aromatic compounds.Pure 1,7-bromo-substituentperylenetetracarboxylatewas synthesized formperylenetetracarboxylate. Owing to the good solubility of perylenetetracarboxylate,the modification of this kind of compound is very important, and is expected to playan important role in biosystems.
