A series of new 2,7-diamino-9-(N-substituted phenyl)-9,10-dihydro-1,8,9-triaza-anthracene-3,6- dicarbonitriles 6a-d were prepared by condensation of malononitrile with 2,6-diamino derivatives 5a-d which have been prepared by the action of sodium dithionite on 2,6-diazido-1-(N-substituted phenyl)-1,4-dihydropyridine-3,5- dicarbaldehydes 4a-d which in turn were prepared by the treatment of sodium azide with 3a-d. The structures of the newly synthesized compounds have been confirmed on the basis of elemental analysis and spectral studies. The newly synthesized title compounds have been screened for their in vitro antimicrobial activities. Some of the compounds exhibited encouraging results. Source

The 0.04 M copper-doped lead iodate crystals grown in silica gel were characterized by Fourier transform infrared (FTIR) spectroscopy, Raman spectroscopy and thermo analytical techniques (TG, DTA, DTG and DSC). Raman and FTIR spectrum clearly indicate that the functional groups of undoped lead iodate were not altered by the addition of the dopant. Thermal analysis suggests that the thermal stability of lead iodate crystals decreases due to copper doping. © 2012 Akadémiai Kiadó, Budapest, Hungary. Source

Lead iodate crystals doped by Zn(II) were grown by silica gel method. Grown crystals were characterized by scanning electron microscopy (SEM), Energy dispersive X-ray spectroscopy (EDAX), X-ray fluorescence spectroscopy (EDXRF) and Non linear optical (NLO) property. SEM pictures shows that no morphological or structural changes take place due to doping. An EDXRF and EDAX study reveals the presence of zinc in doped crystals. The NLO property of the crystal was tested by Nd:YAG laser. Source
