摘要：

The second harmonic generation (SHG) of 29 kinds of thienyl chalcone derivatives with a thiophene ring were examined. A series of 1-{2-(5-bromothienyl)}-3-(4'-halophenyl)propene-3-one showed high SHG activity. Especially 1-(2-thienyl)-3-(4-methylphenyl)propene-1-one had SHG activity 15 times as large as urea and also high blue light region transparency with a cutoff wavelength of 390 nm. A large high quality single crystal of 60 x 15 x 10mm of this compound could be obtained from acetone solution. Analysis of the crystal structure identified it as a monoclinical system of space group P2(1).
