Programmed Site-Selective Palladium-Catalyzed Arylation of Thieno[3,2-b]thiophene

Mono-, di-, tri-, and tetraarylated thieno[3,2-b]thiophenes were synthesized by direct site-selective Pd-catalyzed C?H activation reactions with various aryl bromides in the presence of a phosphine-free Pd(OAc)2/KOAc catalyst system in N,N-dimethylacetamide (DMAc). The arylation of 2-arylthieno[3,2-b]thiophene took place at the C3 position if the 2-aryl substituents possessed electron-withdrawing groups and at the C5 position if they were bulky and possessed electron-donating groups.

Heterocyclic compound, display panel and display device

The invention discloses a heterocyclic compound which has a general formula structure as shown in [chemical formula 1], a di-five-membered heterocyclic parent nucleus in the heterocyclic compound hasa large rigid planar conjugated structure which can improve the intermolecular interaction, is beneficial for intermolecular close packing, and can effectively improve the refractive index of the heterocyclic compound; the heterocyclic compound has a low absorption coefficient in the visible light region, and is suitable for being used as the cap layer material of OLED top emission devices. When the heterocyclic compound is used as a cap layer material of an OLED top emission device, the device luminous efficiency can be effectively improved, and the device long-time working stability is improved. The heterocyclic compound can also be used as an electron transport material or an electron injection material to improve the device light emitting performance.

Acid-base-responsive intense charge-transfer emission in donor-acceptor-conjugated fluorophores

Herein we report on the synthesis and acid-responsive emission properties of donor-acceptor (D-A) molecules that contain a thienothiophene unit. 2-Arylthieno[3,2-b]thiophenes were conjugated with an N-methylbenzimidazole unit to form acid-responsive D-A-t

Palladium-catalyzed C-S coupling: Access to thioethers, benzo[b]thiophenes, and thieno[3,2-b]thiophenes

The first C-S bond formation/cross-coupling/cyclization domino reaction using thiourea as a cheap and easy to handle dihydrosulfide surrogate has been developed. Structurally important biarylthioether, benzo[b]thiophenes, and thieno[3,2-b]thiophene scaffolds are provided in high yield.

Synthesis of New 2-Arylthienothiophenes

2-Arylthienothiophenes 1 have been synthesized by palladium catalysed arylation reactions of thienothiophene 2 and intramolecular cyclisations of 2,3-substituted thiophenes 7.A comparative study of the different methods is presented.
