从生物学到电子工程,二苯并噻吩和亚硒酚被广泛用于非常不同的领域。但是,它们的化合物需要多个合成步骤。在本报告中,我们介绍了二苯并噻吩/硒烯的两步轻松合成方法,即二茚并[1,2-b:2',1'- d ]噻吩-10、11-二酮(DITD)和二茚并[1] ,2-b:2',1' - d ]硒烯-10,11-二酮(DISD)。经由Knoevenagel缩合将化合物进一步转化为二氰基亚乙烯基衍生物。报告了其电子和光电性能,并以密度泛函理论(DFT)计算为后盾。

change in their redox states is a convenient way of controlling self-assembly and hence for advancing supramolecular chemistry. Here we present systematic studies on a selection of extended tetrathiafulvalenes with thienoacene spacers. By cyclic and differential pulse voltammetry and in situ EPR/UV-Vis-NIR spectroelectrochemistry, in combination with computations, we have elucidated how the number
In this report, we introduce a two-step facilesynthesis of a dibenzo thiophene/selenophene, namely diindeno[1,2-b:2′, 1′-d]thiophene-10, 11-dione (DITD) and diindeno[1,2-b:2′, 1′-d]selenophene-10, 11-dione (DISD). The compounds were further converted via a Knoevenagel condensation to dicyanovinylene derivatives. Their electronic and optoelectronic properties, backed by density functional theory (DFT)
