About 66% of the salts in the combinatorial library were found to show moderate to good gelling ability in various polar and nonpolar solvents including commercial fuels such as petrol. The majority of the salts having a rigid, unsaturated anionic backbone (maleate, phthalate, and isophthalate) did not show gelation; only the corresponding hexadecylammonium salts showed gelation. Some of the representative gels were characterized by rheology, small-angle neutron scattering (SANS), optical microscopy (OM), and scanning electron microscopy (SEM). Single-crystal structures of two gelator and two nongelator salts were also discussed in the context of supramolecular synthon and structure-property correlation.</p>1 aSahoo, Pathik1 aAdarsh, N., N.1 aChacko, George, E.1 aRaghavan, Srinivasa, R.1 aPuranik, Vedavati, G.1 aDastidar, Parthasarathi  uhttps://library.ncl.res.in/content/combinatorial-library-primaryalkylammonium-dicarboxylate-gelators-supramolecular-synthon-001540nas a2200193   4500008004100000022001400041245007900055210006900134260011000203300001400313490000600327520079100333100001801124700002601142700001801168700001901186700002801205856011301233       2011                        eng d  a1744-683X00aFerrocene based organometallic gelators: a supramolecular synthon approach0 aFerrocene based organometallic gelators a supramolecular synthon  aTHOMAS GRAHAM HOUSE, SCIENCE PARK, MILTON RD, CAMBRIDGE CB4 0WF, CAMBS, ENGLANDbROYAL SOC CHEMISTRYcFEB  a3634-36410 v73 a<p>The supramolecular synthon namely primary ammonium dicarboxylate (PAD) synthon has been exploited to generate a new series of salt based low molecular weight gelators (LMWGs) derived from ferrocenedicarboxylic acid (FDCA) and primary amines Me-(CH2)(n)-NH2 (n = 3-15). While most of the salts are capable of forming gels with DMSO and DMF, nearly all of them show a tendency to form gels with at least one of the solvents studied. Structure property correlation based on single crystal and powder X-ray diffraction data in combination with optical-, scanning-, and transmission-electron microscopy reveals that the supramolecular synthon approach adopted herein for designing LMWGs is indeed useful and allows one to get an easy access to a new series of organometallic gelators.</p>1 aSahoo, Pathik1 aPuranik, Vedavati, G.1 aPatra, A., K.1 aSastry, P., U.1 aDastidar, Parthasarathi  uhttps://library.ncl.res.in/content/ferrocene-based-organometallic-gelators-supramolecular-synthon-approach-0
