Abstract 3-Amino-4,6-dimethylpyrazolopyridine was applied as a precursor for the synthesis of some new pyridopyrazolo-triazine and pyridopyrazolo-triazole derivatives through diazotization, followed by coupling with many 2-cyanoacetamide compounds, e

Abstract A new series of pyridine, thiazole, and pyrazole analogues were synthesized. The pyridone analogues 4a-e were synthesized by treating N-aryl-2-cyano-3-(4-(diphenylamino)phenyl)acrylamides 3a-e with malononitrile. Many 4-arylidene-thiazolidin

Abstract A new series of metal-free organic dyes (SM1-5) with dual anchors are synthesized for application in dye-sensitized solar cells (DSSC). Here, a simple triphenylamine (TPA) moiety serves as the electron donor, while di-cyanoacrylamide and di-

A number of important fused heterocyclic systems have been prepared by the reaction of 4-((3,5-diamino-1H-pyrazol-4-yl)-diazenyl)-N-(thiazol-2-yl)-benzenesulfonamide with some bifunctional nucleophiles such as ethyl acetoacetate, acetylacetone or ary

We have synthesized new metal-free dyes (HB-1–8) containing bifuran/biphenyl derivatives for dye-sensitized solar cells. Dye HB-3 exhibited the highest efficiency among the eight investigated dyes, reaching 5.51% with a VOC value higher than N3.

Background: On examining the RNFL thickness by OCT, the media opacity caused by cataract will increase light scattering and absorption, so the RNFL thickness measurement can be increased after uncomplicated cataract surgery also, inflammatory r
