In particular, two novel multifunctional metallogels were readily prepared at room temperature by simple mixing of stock solutions of Cu-II acetate monohydrate or Cu-II perchlorate hexahydrate and oxalic acid dihydrate. Formation of different polymorphs and unprecedented proton conduction under anhydrous conditions were also demonstrated with some of these materials.</p>10aCopper10alow-molecular-weight ligands10ametallogels10aproton conductivity10asupramolecular chemistry1 aSaha, Subhadeep1 aSchoen, Eva-Maria1 aCativiela, Carlos1 aDiaz, David, Diaz1 aBanerjee, Rahul  uhttps://library.ncl.res.in/content/proton-conducting-supramolecular-metallogels-lowest-molecular-weight-assembler-ligand-001789nas a2200181   4500008004100000022001400041245010200055210006900157260007100226300001600297490000800313520109200321100002001413700001701433700001901450700002001469856011801489       2014                        eng d  a0002-786300aPhotocatalytic metal-organic framework from cds quantum dot incubated luminescent metallohydrogel0 aPhotocatalytic metalorganic framework from cds quantum dot incub  a1155 16TH ST, NW, WASHINGTON, DC 20036 USAbAMER CHEMICAL SOCcOCT  a14845-148510 v1363 a<p>Cadmium sulfide (CdS) quantum dots (&lt;10 nm in size) have been successfully synthesized in situ without any capping agent in a Zn(II)-based low-molecular-weight metallohydrogel (ZAVA). Pristine ZAVA hydrogel shows blue luminescence, but the emission can be tuned upon encapsulation of the CdS quantum dots. Time-dependent tunable emission (white to yellow to orange) of the CdS incubated gel (CdS@ZAVA gel) can be attributed to sluggish growth of the quantum dots inside the gel matrix. Once CdS quantum dots are entrapped, their augmentation can be stopped by converting the gel into xerogel, wherein the quantum dots remains embedded in the solid xerogel matrix. Similar size stabilization of CdS quantum dots can be achieved by means of a unique room-temperature conversion of the CdS incubated ZAVA gel to CdS incubated MOF (CdS@ZAVCl) crystals. This in turn arrests the tunability in emission owing to the restriction in the growth of CdS quantum dots inside xerogel and MOF. These CdS embedded MOFs have been utilized as a catalyst for water splitting under visible light.</p>1 aSaha, Subhadeep1 aDas, Gobinda1 aThote, Jayshri1 aBanerjee, Rahul  uhttps://library.ncl.res.in/content/photocatalytic-metal-organic-framework-cds-quantum-dot-incubated-luminescent-0
