Popis:	This work describes the synthesis of new, highly soluble squaraine dyes, which have absorption maxima over 900 nm in solution. The absorption spectra of their spin-coated films show broad absorption bands, which are caused by aggregation phenomena. The absorption bands in the solid phase are red-shifted compared to those in solution. Because of these characteristics and nonlinear optical data which were obtained by Z-scan measurements, the new substances are principally useful for optical switches.
