1) Microwave assisted synthesis and antimicrobial activity of novel 1-[1/2-(1-Benzyl-1H-[1,2,3]triazol-4-ylmethoxy)-naphthalen-2/1-yl]-3-(1-phenyl-3-aryl-1H-pyrazol-4-yl)-propenones
A series of novel 1-[1/2-(1-Benzyl-1H-[1,2,3]triazol-4-ylmethoxy)-naphthalen-2/1-yl]-3-(1-phenyl-3-aryl-1H-pyrazol-4-yl)-propenones were design and synthesized by Click reaction followed by Claisen-Schmidt condensation under microwave irradiation and conventional heating methods. The structures of newly synthesized compounds have been established on the basis of elemental analysis, IR, 1H & 13C NMR and mass spectral data. All the compounds were screened for their antimicrobial activity.Keywords 1 2 3-triazole pyrazoles chalcones antimicrobial activity microwave irradiation DETAILS PDF OF ARTICLE © 2015 ACG Publications.

2) Bulk heterojunction solar cells of three polythienothiophenes
Semiconducting conjugated copolymers poly(3-phenyl-2-(thiophen-2-yl)thieno[3,2-b]thiophene) (PTTPh), poly(3-(4-methoxyphenyl)-2-(thiophen-2-yl)thieno[3,2-b]thiophene) (PTTPh-OMe) and poly(3-(4-N,N-dimethylaminophenyl)-2-(thiophen-2-yl)thieno[3,2-b]thiophene) (PTTPh-N(CH 3) 2), which were synthesized previously through Suzuki coupling method, were fabricated for solar cell applications. The devices had a structure of glass/ITO/PEDOT:PSS/polymer:PC61BM/Al. Bulk heterojunction photovoltaic cells were prepared as blends of PTTPh, PTTPh-OMe, PTTPh-N(CH 3) 2 and PC61BM in a 1:1 ratio, which delivered power conversion efficiencies of 0.43%, 0.039% and 0.027%, respectively, without addition of additives or device optimization.Keywords Thienothiophene polythienothiophene organic solar cell DETAILS PDF OF ARTICLE © 2015 ACG Publications.

3) Synthesis, characterization and antimicrobial activities of amide derivatives of febuxostat intermediate
A series of new carboxamide derivatives of 3-(4-(5-(ethoxycarbonyl)-4-methylthiazol-2-yl)phenoxy)propionic acid were synthesized by Schotten-Baumann reaction. The newly synthesized compounds were characterized by IR, NMR and mass spectral analysis. The target molecules were evaluated for their efficacy as antimicrobial agents in vitro by disc diffusion method. Compounds 4c, 4f, 4g and 4i showed high inhibitory activity.Keywords Febuxostat intermediate carboxamide derivatives antimicrobial activity DETAILS PDF OF ARTICLE © 2015 ACG Publications.

4) Simple and novel synthetic method to mixed-donor podand
An efficient method for the synthesis of new compounds of dibenzo podand containing mixed-donor atom is described. The key starting materials for these podand was successfully prepared in 92% yield from 2-aminophenol and benzaldehyde in water. The structures of these new compounds were confirmed on the basis of IR, 1H NMR and 13C NMR and Ms spectroscopic data.Keywords Mix donor Cesium carbonate Podand SDS Amino phenol DETAILS PDF OF ARTICLE © 2015 ACG Publications.
