Study on photoelectric properties of perylene polyimide;

The perylene polyimide containing donor-acceptor unit was designed, synthesized and characterized by elemental analysis, UV-visible spectrum, gel permeation chromatograph, nuclear magnetic resonance, infrared spectrum, and thermogravimetry.

In this paper, three perylene bisimides with carboxylic group were synthesized, and their spectra properties were studied.

Recently,perylene bisimide derivatives have been extensively studied as one of the most functional materials,providing prospects for applications in organic solar cells,because of their cheap price,good thermal and photochemical stability,high electron affinity,high absorption and fluorescence quantum yield.

In this thesis,perylene bisimide-bridged bis-(permethyl-β-cyclodextrins),perylene bisimide-bridged bis-(permethyl-ethylenediamino-β-cyclodextrins), naphthalene diimide and pyromellitimide bridged permethyl-β-cyclodextrin,and a series of calixarene derivatives were synthesized.

Electron mobility of two fluorinated perylene diimide compounds was measured by the method of space-charge-limited current: one was N,N'-bisperfluorophenyl-3,4,9,10-perylenetetracarboxylic diimide (1), the other was N,N'-bis(1,1-dihydroperfluorooctyl)-3,4,9,10-perylenetetracarboxylic diimide (2).

In this dissertation, based on molecular and material designs, electron-deficient nitrogen heterocycles were introduced to the traditional organic n-type materials of perylene diimides.
