The first examples of monoazo dyes absorbing in the near infrared (up to 806 nm in dimethyl sulphoxide) have been prepared from 2-(4-amino-2-acetylaminophenylazo)-4-chloro-5-formylthiazoles by condensing the formyl group with suitably electronegative active methylene compounds under base catalysed conditions.

The in situ prepared polyurethane films of the thiazolylazo NLOphores showed d33values of 38—49 pm V−1. The temporal stability of the poled NLOphore was in the following order of the polymers: network > side chain > main chain.
