A materials scientist in Turkey has retracted a paper in the journal Tetrahedron after realizing that there was more to the compounds he was studying than he thought.
The article, “Novel donor–acceptor type thiophene pyridine conjugates: synthesis and ion recognition features,” appeared in April and was written by Fatih Algi, of the Laboratory of Organic Materials at Canakkale Onsekiz Mart University.
Here’s the notice:

Although the synthetic route to compounds 1-3 is still valid, further research by the author indicated that the ion selectivity of the compounds can be variable. Apologies are offered to readers of the journal that this irreproducibility was not detected by the author before the submission and publication process.
