In spite of their different groups, they have the similarity of exhibiting a stable 3+ oxidation state. Here we have prepared Fe(III) and Al(III) based coordination polymers in the form of metal-organic gels with the 4,4', 4 `'-tricarboxyltriphenylamine (TCA) ligand, namely Fe-TCA and Al-TCA, and evaluated some important physicochemical properties. Specifically, the electrical conductivity, redox-activity, porosity, and electrocatalytic activity (oxygen evolution reaction) of the Fe-TCA system were noted to be remarkably higher than those of the Al-TCA system. As for the photophysical properties, almost complete quenching of the fluorescence originating from TCA was observed in case of the Fe-TCA system, whereas for the Al-TCA system a significant retention of fluorescence with red-shifted emission was observed. Quantum mechanical calculations based on density functional theory (DFT) were performed to unravel the origin of such discriminative behaviour of these coordination polymer systems.</p>1 aDhara, Barun1 aSappati, Subrahmanyam1 aSingh, Santosh, K.1 aKurungot, Sreekumar1 aGhosh, Prasenjit1 aBallav, Nirmalya  uhttps://library.ncl.res.in/content/coordination-polymers-feiii-and-aliii-ions-tca-ligand-distinctive-fluorescence-co2-uptake01296nas a2200193   4500008004100000245012000041210006900161260000800230300001400238490000700252520059900259100001700858700001900875700001700894700002200911700002100933700001800954856013000972       2017                        eng d00aCisplatin-induced self-assembly of graphene oxide sheets into spherical nanoparticles for damaging sub-cellular DNA0 aCisplatininduced selfassembly of graphene oxide sheets into sphe  cJAN  a1409-14120 v533 aThis report describes the hitherto unobserved cisplatin induced self-assembly of 2D-graphene oxide sheets into 3D-spherical nano-scale particles. These nanoparticles can encompass dual DNA damaging drugs simultaneously. A combination of confocal microscopy, gel electrophoresis and flow cytometry studies clearly demonstrated that these novel nanoparticles can internalize into cancer cells by endocytosis, localize into lysosomes, and damage DNA, leading to apoptosis. Cell viability assays indicated that these nanoparticles were more cytotoxic towards cancer cells compared to healthy cells.1 aNandi, Aditi1 aMallick, Abhik1 aMore, Piyush1 aSengupta, Poulomi1 aBallav, Nirmalya1 aBasu, Sudipta  uhttps://library.ncl.res.in/content/cisplatin-induced-self-assembly-graphene-oxide-sheets-spherical-nanoparticles-damaging-sub
