摘要：

By refluxing squaric acid 4 with N,N-disubstituted 2-amino-selenazoles 8 in a mixture of toluene and 1-butanol a new type of 2-amino-5-selenazolyl-substituted squaraines 9 was obtained. These compounds are deeply coloured dyes with intense long-wavelength absorptions at about 620-700 nm in solution and at about 900 nm in the solid state. (C) 1999 Elsevier Science Ltd.
