Abstract

With the goal of improving the long term redox stability of dithieno [3, 2-b: 2′, 3′-d] thiophene (DTT), we synthesized derivatives with differently sized substituents. It is well known that substituents in the 2, 6 positions of DTT are active in this respect. We provide in this article more insight into mechanism. The present study provides the first support for a size effect. Large size substituents in the 2, 6 positions of the DTT are more effective than ...
