Synthesis and SHG activity of chiral Schiff base derivatives |

Abstract: | Six kinds of chiral Schiff bases have been synthesized by the condensation of chiral aromatic amine and aromatic aldehyde. The absorption curves of UV visible have been measured and it is found that their maximum absorption wavelengths are all in the ultraviolet region. The absorption wavelength of Schiff bases compounds causes red shift with the weak electron donor group on the aromatic amine ring and the electron acceptor group on the aromatic aldehyde ring. The second harmornic generation of synthesized compounds have been measured by the powder method and it is found that two samples possess SHG activity. |
