Nanometre films of pseudoisocyanine N-alkyl-substituted J-aggregates are obtained on glass substrates by spin-coating from organic dye solutions. The optical and nonlinear optical properties of these films are investigated. These films are shown to possess a high optical quality over the area of size more than 30 x 30 mm and a high photochemical stability. These films feature strong absorption saturation at the maximum of excitonic absorption of the aggregates. The radiative damage threshold of the films at the maximum of 2 the excitonic absorption was measured to be 5 MW cm(-2). The dispersion of optical nonlinearity of the films within the J-band is measured by the Z-scan and probe field methods. The films can be used as two-dimensional optical light-controlled switches.
