Abstract:
: Benzo[b]thiophenes are aromatic heterocyclic compounds containing benzene and thiophene rings. This class of heterocycles is present in a large number of natural and non-natural compounds. Benzo[b]thiophene derivatives have a broad range of applications in medicinal chemistry such as antimicrobial, anticancer, antioxidant, anti-HIV and antiinflammatory activities. The use of benzo[b]thiophene derivatives in other fields has also been reported. Various benzo[b]thiophenes compounds have been employed as organic photoelectric materials, while several benzo[b]thiophenes have been used as organic

Abstract:
Methods for the synthesis of keto derivatives of the little studied naphtho[1,8-bc]thiophene system have been developed. Using the readily available benzothiophene derivative 6,7-dihydrobenzo[b]thiophen-4(5H)-one 4, a 3-keto-naphtho[1,8-bc]thiophene 14 was synthesized by a tin(IV) chloride catalyzed cyclization of the acid chloride derivative of the saturated acid 13b. The bicyclic ketone 4 was also used to prepare the keto-sulfoxide 7, which was cyclized to the 4-keto-naphtho[1,8-bc]thiophene system 9 in a Pummerer-type rearrangement.

A series of new π-conjugated donor (D) and acceptor (A) dyad comonomers were prepared using Suzuki coupling protocols. The D–A comonomers consisting of thiophene/bithiophene as donors and pyridine/pyrimidine as acceptors were prepared to investigate their photophysical and electrochemical properties. The dyads were spectroscopically confirmed to be highly conjugated. This was further supported by the X-ray crystal structure of the bithophene–pyridine dyad that showed all the heterocycles to be coplanar. It was further found that the fluorescence yields (Φfl) of the dyads were highly dependent

A series of carbazole-thiophene dimers,P1–P9, were synthesized using Suzuki-Miyaura and Ullmann coupling reactions. InP1–P9, carbazole-thiophenes were linked at the N-9 position for different core groups via biphenyl, dimethylbiphenyl, and phenyl. Electronic properties were evaluated by UV-Vis, cyclic voltammogram, and theoretical calculations. Particularly, the effects of conjugation connectivity on photophysical and electrochemical properties, as well as the correlation between carbazole-thiophene and the core, were studied.

Fiesselmann thiophene synthesis was applied for the convenient construction of thieno[3,2-b]thiophene derivatives. Thus, new 5- or 6-aryl-3-hydroxythieno[3,2-b]thiophene-2-carboxylates were obtained by condensation of 5- or 4-aryl-3-chlorothiophene-2-carboxylates, respectively, with methyl thioglycolate in the presence of potassium tert-butoxide. The saponification of the resulting esters, with decarboxylation of the intermediating acids, gave the corresponding thieno[3,2-b]thiophen-3(2H)-ones. The latter ketones were used to synthesize new N,S-heterotetracenes, namely 9H-thieno[2',3':4,5]thie

Abstract:
Electronic conductive polymers such as polyacetylenes, polyanilines and polythiophenes, are not easy to process due to lack of tractability and solubility. Chemical modifications of the polythiophenes backbone have been utilized to improve the processibility.

The precursor will be used in the preparation of various poly {[3- oligo(dimethylsiloxane)]thiophene-co-3-methylthiophene} random copolymers. By increasing the

The polyvalent properties of dendrimers are widely used in biomedical scaffolds and catalysis. The internal cavities with the structure can also be harnessed for encapsulation. This application has evoked interest especially within the bio-medical field, using dendrimers as host molecules to increase the solubility of drug molecules.
