p-Aminostyrene - Reference Information
| EPA chemical information | Information provided by: ofmpub.epa.gov (external link) |
| Use | 4-ethyleneaniline is an organic intermediate, which can be obtained by reducing p-nitrostyrene. It has been reported in the literature that 4-ethylene aniline can be used to prepare a D-A-π-A type polymeric complex dye sensitizer PBDTT-SF-Cd with ethylene benzene and p-ethylene phenol methylamine derivative cadmium complexes as auxiliary electron acceptors. Dye-sensitized solar cell (DSSC) is one of the organic solar cells with the most potential for research and development at present, attracting in-depth research all over the world. Dye-sensitizer can generate photogenic electrons after absorbing sunlight, which is the key photosensitive material of dye-sensitized solar cell (DSSC). |
