Abstract:
To maximize the potential of poly(3-hexylthiophene) (P3HT) as a nonlinear optical material, we examined the conditions for fabricating thin films. The results indicate that the third-order optical susceptibility χ (3) , which was determined by electroabsorption spectroscopy, is fourfold enhanced when thin films are drop cast from an anhydrous chloroform solution in an inert atmosphere, compared with the χ (3) of spin-coated thin films prepared in an ambient atmosphere. Fabricating the thin films in an O 2 - and water-free environment is essential for obtaining large χ (3) values. Under these conditions, we determined the maximum value of the imaginary part of χ (3) for P3HT to be 2.2 ×10 -9 esu.
