Paper Abstract

The Z-scan technique was used to investigate the third-order optical nonlinearity of MEH-PPV and PPV thin-films. The measured magnitude of every x(3) of the two polymers was the order of 10-9 esu and the x(3) of MEH-PPV was larger than that of PPV's. At the same time, the crystal orbital program was used to calculate the electronic structure of two polymers. According to our discussion, the p-(pi) conjugation between the oxygen atom and the PPV main chain in the MEH-PPV should be one of the main reasons for MEH-PPV having the larger x(3) value.
