Oligothiophene systems

Other low-molecular systems that have been investigated in waveguiding films are the guest-host system Alq3 DCM (see below for the emission in tme resonators), arylamines, and oligothiophenes. TPD (6) shows an emission peak in thin films at 418 nm when pumped with 35-ps pulses at 347 nm [185]. The... [Pg.136]

Poly(3-alkyl-a-thiophene) systems show significant third-order nonlinear susceptibilities ( ) Though, oligothiophenes have been studied for their third-order susceptibilities, accurate third-order optical nonlinearity data obtained by degenerate four-wave mixing or electric-field-induced second harmonic generation (EFISH) are difficult to attain reliably on samples with poor solubility characteristics (92MM1901).
