Dithieno [3,2-b:2′,3′-d]thiophene (DTT): an emerging heterocyclic building block for future organic electronic materials & functional supramolecular chemistry. Heterocyclic compounds being potent biochemical materials are ubiquitous molecules in our life. Amongst, the five membered aromatic ring systems, thiophene has emerged as a ...
18 Φεβ 2002 · Dithieno[3,2-b:2′,3′-d]thiophene (DTT) 1 has found use in materials for electronic and optical applications. Optical phenomena such as two-photon absorption, 1. , 2. electro-luminescence, 3. , 4. photochromism, 5 and two-photon excited fluorescence 6 in DTT-based materials have been investigated.
14 Απρ 2023 · The single crystal structure of 2,6-DADTT presents classical herringbone packing with multiple intermolecular interactions, including S⋯S (3.470 Å), S⋯C (3.304 Å, 3.391 Å, 3.394 Å) and C-H⋯π (2.763 Å, 2.822 Å, 2.846 Å, 2.865 Å, 2.885 Å, 2.890 Å) contacts.
24 Αυγ 2016 · Abstract A new synthetic method for dithieno[3,2-b:2′,3′-d]thiophenes was developed. The approach involves three steps starting from thiophene: tetraiodation of thiophene, selective dialkynylations on the 2,5-positions of the tetraiodothiophene, and finally CuI/TMEDA catalyzed double annulations of 2,5-dialkynyl-3,4-diiodothiophenes by Na2S ...
