In this paper, a intermediate compound of solar cell materials and plant activator was reported. 4-hexyl aniline as the raw material, through a series of reactions to get a new compound E and characterized by 1H NMR and IR. This compound has excellent solubility in common solvents and as a promising candidate of synthesizing organic solar cell materials and plant activator.

Novel hole-transporting materials (M1, M2) containing triphenylamine and dipyridine units have been synthesized and characterized. Two compounds have excellent solubility in common solvents. The optical, electrochemical and thermal properties of the materials were studied in detail. The results show that two compounds have green emission in dichloromethane, high thermal stability and proper HOMO levels. The properties of compounds M1 and M2 indicate that two compounds are candidates for the application in Organic light-emitting devices as hole-transporting materials.

Organic light-emitting materials D1~D3 containing triphenylamine donors, bipyridine acceptors and olefinic linkers were synthesized and characterized. The optical, electrochemical properties of materials were studied by UV-Vis spectra, fluorescence emission spectra and cyclic voltammetry method. The results show that the maximal absorption peaks of three compounds are in the range of 404nm~408nm and fluorescence emission peaks at the region of 534nm~557nm in dichloromethane solutions, respectively. Cyclic voltammetry measurement showed that these compounds had HOMO energy level in the range of-5.02eV~-5.16eV, which is proper for hole injection. The properties indicate that these compounds have potential for the application as light-emitting materials or hole-transporting materials.
