摘要
The synthesis and spectroscopic properties of series of new aniline–based squarine dyes have been presented. The effect of solvent polarity, hydrogen bonding and substituent on spectroscopic properties of 1,3-bis(phenylamino)squarine (SQG1), 1,3-bis(4-bromophenylamino)squarine (SQG2), 1,3-bis(4-ethylphenylamino)squarine (SQG3), 1,3-bis(4-ethoxyphenylamino)squarine (SQG4), 1,3-bis(4-nitrophenylamino)squarine (SQG5), 1,3-bis(4-chlorophenylamino)squarine (SQG6), 1,3-bis(4-iodophenylamino)squarine (SQG7), 1,3-bis(4-aminobenzosulfo)squarine (SQG8) 1,3-bis(4-methylphenylamino)squarine (SQG9) 1,3-bis(4-hydroxyphenylamino)squarine (SQK1) in ten selected solvents were studied.
