摘要：A novel near infrared ratiometric fluorescent chemosensor based on triphenylamine, thiophene and benzothiadiazole has been developed. The emission wavelength of sensor DTPAT-BT-S was in the near infrared region. The wavelength changed from 656 nm to 723 nm, and got a rather long stokes shift about 170 nm. The sensor showed a very high selectivity towards Hg2+ ions. (C) 2017 Elsevier Ltd. All rights reserved.
