Revised Date: 27 April 1998

N,N-Bis(2-hydroxyethyl)amino-1,3-benzenediol(1a) and its analogs 1b~1g have been synthesized. By condensation of squaric acid with 1a~1g, a class of novel multiarm-squaraines, namely 1,3-bis[4-N,N-bis(2-hydroxyethyl)amino-2,6-dihydroxyl phenyl] squaraine(2a) and its analogs(2b~2g) were obtained. The compounds were designed to improve the donor acceptor donor charge transfer(D-A-D CT) of squaraines. The spectra properties of the compounds have been discussed.
