Abstract
Abstract Redox driven chemiluminescent (CL) compounds based on thienyl and pyridazine systems, namely 2,3-dihydrothieno(3,4-d)pyridazine-1,4-dione (T-Lum) and 5,7-di-thiophen-2-yl-2,3-dihydro-thieno[3,4-d]pyridazine-1,4-dione (TTT-Lum), were synthesized. Soluble compounds both in organic media and basic aqueous solution were found to give CL and electroluminescent (EL) reactions by the treatment of oxidants (H 2 O 2 and KMnO 4 ) and by an external potential pulse on the working electrode, respectively. Furthermore, the CL reaction can be speeded up by Fe 3+ ion or blood samples. On the other hand, one of the compounds, TTT-Lum, can be polymerized successfully via electrochemically both in 0.1 M LiClO 4 /acetonitrile containing 5% of borontrifluoro diethylether (BF 3 -Et 2 O) and neat BF 3 -Et 2 O solution. The corresponding polymer film (PTTT-Lum) bearing CL units has a very stable and a well-defined reversible redox couple. Also, the electrochromic polymer film has a band gap of 1.74 eV and exhibits EL behavior.
