Abstract

Thiadiazole derivatives R 0300Synthesis and Antibacterial Activity of Some 5-(4-Biphenylyl)-7-aryl[3,4-d][1,2,3]-benzothiadiazoles. -The antibacterial activity of the title benzothiadiazoles, e.g. (VIII), is assessed in side-by-side comparison with ciprofloxacin and norfloxaxin against some Gram-positive and Gram-negative bacteria. Compounds (VIII) display a better activity against Gram-positive organisms than the reference compounds. However, compounds (VIII) are nearly inactive against Gram-negative bacteria. -(BALASANKAR, T.; GOPALAKRISHNAN, M.; NAGARAJAN*, S.; Eur.

Efficient Molecular Modelling of Butterfly-Shaped Hole Transport Materials With Remarkable Photovoltaic Properties For High-Performance Organic Solar Cells

“…A semiconductor Spiro-OMETAD have high molecular weight, high cost and di cult to synthesize replace by low molecular weight hole transporting material (HTMs) by using recently computational research techniques to ensure the high yield 2,3 . For the synthesis of HTMs electron-donating moieties are being used like triphenylamines (TPA), diphenylamine's (DPA), as these had been already studied in Dye Sensitize Solar Cells (DSSC) 1,3−6 . The benzothiadiazole (BT) group is a backbone of frequently used organic semiconductor 7,8 . Basically, it is a heterocyclic system with electron withdrawing nature can be used in transportation of charge carriers like negative charge and create hole.…”

Design, synthesis, characterization, antibacterial and antifungal activities of a novel class of 5,7-diaryl-4,4-dimethyl-4,5,6,7-tetrahydropyridino[3,4-d]-1,2,3-selenadiazoles

“…It is well known that a number of heterocyclic compounds containing nitrogen, sulfur and selenium possess different pharmacophoric properties [1][2][3]. However, reports about selenium-containing heterocycles are scanty, [4,5] although some of them are used as chemotherapeutic agents [1,6].…”
