Abstract
The |n2| of poly(aryleneethynylenes), a novel class of conjugated polymers, their derivatives, and model substances was studied by time-resolved degenerate four-wave mixing. The measurements were performed in solutions at 1047 nm with picosecond time resolution and on thin films at 800 nm with femtosecond time resolution. A time response of the nonlinearities faster than the pulse durations used was found. |n2| values of as much as 4.9×10−13 cm2/W were measured on thin films of the polymers.
