A novel directly-linked donor-acceptor-donor (D-A-D) type system, which is based on 2,3-dihydro-1H-pyrrolo[3,4-d]pyridazine-1,4(6H)-dione as the A unit and thiophene as the D units, respectively, is designed, synthesized, and characterized by spectroscopic methods. This novel D-A-D system can be used for the fluorogenic detection of Cu2+ among other ions. (C) 2012 Elsevier Ltd. All rights reserved.
