Synthesis And Properties Of The Structures Containing Polycyclic Aromatic Hydrocarbon

Polycyclic aromatic hydrocarbons are one kind of compounds containing more than two benzene rings or heterocycles. Because of their special planarity and π conjugated system, they have a wide range of applications in the field of optoelectronic function materials. We designed and synthesized one kind of novel bistriphenylamine-substituted fluoranthene derivatives, used them as sensitizers and tested their photovoltaic performances. Then we optimized the conditions and synthesis method of phenazine derivatives. The main contents are summarized as follows:In chapter one, the background, working principles and recent progress of DSSC and the mechanism of C-N bond forming are introduced.In chapter two, a series of bistriphenylamine-substituted fluoranthene derivatives have been designed and synthesized. Their photophysical and photovoltaic performances are tested. D2achieved the highest conversion efficiency of4.57%(Jsc=8.57mA cm-2, VOC=0.76V, ff=0.70).In chapter three, the reaction of copper-catalyzed Ullmann coupling and C-H amination including the types of catalysts, bases and ligands were optimized. The species of substrate were developed, and by this method unsymmetry derivatives can be synthesized.In chapter four, a series of compounds that containing10,11-dihydrodiindeno[1,2-b:2’,1’-d]thiophene have been synthesized. Their absorption and fluorescence spectra were tested.In chapter five, conclusion.
