A nonconventional gelator (\n                    <jats:italic>R<\/jats:italic>\n                    )\u2010NDI, devoid of any long alkyl chains, exhibited spontaneous gelation in tetra\u2010chloroethylene (TCE). Based on X\u2010ray crystallography and powder X\u2010ray diffraction studies, it was established that a ladder\u2010like hydrogen\u2010bonded chain formation between the 1,3\u2010dihydroxyl group leads to the fibrillar structures with preferential helicity. Likewise the (\n                    <jats:italic>S<\/jats:italic>\n                    )\u2010isomer also exhibited identical gelation and mesoscopic structure but produced fibrils with the opposite handedness. Intriguingly, an equimolar mixture of the (\n                    <jats:italic>R<\/jats:italic>\n                    )\u2010 and (\n                    <jats:italic>S<\/jats:italic>\n                    )\u2010isomers did not show any gelation ability, rather a macroscopic precipitation was observed and, in sharp contrast to the individual isomers, the morphology of the mixture showed ill\u2010defined near spherical agglomerates. Differential scanning calorimetry (DSC) studies revealed an identical crystallization peak for the supramolecular polymer produced from the enantiopure gelators ((\n                    <jats:italic>R<\/jats:italic>\n                    )\u2010 or (\n                    <jats:italic>S<\/jats:italic>\n                    )\u2010isomer), which was absent in their equimolar mixture. However, mixtures of the two isomers with enantiomeric excess retrieved the gelation ability and preferential helicity demonstrating that chiral amplification is operative in the present system through the so\u2010called \u201cmajority rule\u201d effect. Chirality induction was also realized by the \u201csergeant and soldier\u201d principle in the supramolecular assembly of an achiral NDI gelator in the presence of either the (\n                    <jats:italic>R<\/jats:italic>\n                    )\u2010 or (\n                    <jats:italic>S<\/jats:italic>\n                    )\u2010isomer as the chiral dopant. However, the strong helical bias induced by the chiral gelator was found to be opposite in nature compared to that found in the self\u2010assembly of the pure chiral gelator that has been rarely reported in the literature. Flash\u2010photolysis time\u2010resolved microwave conductivity (FP\u2010TRMC) measurements indicated the strong positive impact of the gelation on the electrical conductivity.\n                  <\/jats:p>","DOI":"10.1002\/chem.201704825","type":"journal-article","created":{"date-parts":[[2017,11,27]],"date-time":"2017-11-27T06:42:43Z","timestamp":1511764963000},"page":"1938-1946","source":"Crossref","is-referenced-by-count":25,"title":["Supramolecular Chirality Issues in Unorthodox Naphthalene Diimide Gelators"],"prefix":"10.1002","volume":"24","author":[{"given":"Goutam","family":"Ghosh","sequence":"first","affiliation":[{"name":"Polymer Science Unit Indian Association for the Cultivation of Science  700032 Kolkata India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mithun","family":"Paul","sequence":"additional","affiliation":[{"name":"Department of Organic Chemistry Indian Association for the Cultivation of Science  700032 Kolkata India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tsuneaki","family":"Sakurai","sequence":"additional","affiliation":[{"name":"Department of Molecular Engineering Graduate School of Engineering Kyoto University  Nishikyo-ku Kyoto Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wakana","family":"Matsuda","sequence":"additional","affiliation":[{"name":"Department of Molecular Engineering Graduate School of Engineering Kyoto University  Nishikyo-ku Kyoto Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shu","family":"Seki","sequence":"additional","affiliation":[{"name":"Department of Molecular Engineering Graduate School of Engineering Kyoto University  Nishikyo-ku Kyoto Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4199-4382","authenticated-orcid":false,"given":"Suhrit","family":"Ghosh","sequence":"additional","affiliation":[{"name":"Polymer Science Unit Indian Association for the Cultivation of Science  700032 Kolkata India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2018,1,4]]},"reference":[{"key":"e_1_2_7_1_1","unstructured":"\u00a0"},{"key":"e_1_2_7_2_2","volume-title":"Chirality in Natural and Applied Science","year":"2002"},{"key":"e_1_2_7_3_2","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1521-3773(19991203)38:23<3418::AID-ANIE3418>3.0.CO;2-V"},{"key":"e_1_2_7_3_3","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1521-3757(19991203)111:23<3624::AID-ANGE3624>3.0.CO;2-X"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1039\/c3cs60068h"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1021\/acs.chemrev.6b00354"},{"key":"e_1_2_7_6_1","unstructured":"\u00a0"},{"key":"e_1_2_7_7_2","doi-asserted-by":"publisher","DOI":"10.1021\/cr990120t"},{"key":"e_1_2_7_8_2","doi-asserted-by":"publisher","DOI":"10.1039\/c1cc11137j"},{"key":"e_1_2_7_9_2","doi-asserted-by":"publisher","DOI":"10.1021\/ar700266f"},{"key":"e_1_2_7_10_1","unstructured":"\u00a0"},{"key":"e_1_2_7_11_2","doi-asserted-by":"publisher","DOI":"10.1039\/C4SM00507D"},{"key":"e_1_2_7_12_2","doi-asserted-by":"publisher","DOI":"10.1021\/cr500671p"},{"key":"e_1_2_7_13_1","unstructured":"\u00a0"},{"key":"e_1_2_7_14_2","doi-asserted-by":"publisher","DOI":"10.1021\/cr030070z"},{"key":"e_1_2_7_15_2","doi-asserted-by":"publisher","DOI":"10.1021\/cr500633b"},{"key":"e_1_2_7_16_1","unstructured":"\u00a0"},{"key":"e_1_2_7_17_2","doi-asserted-by":"publisher","DOI":"10.1039\/B809359H"},{"key":"e_1_2_7_18_2","doi-asserted-by":"publisher","DOI":"10.1021\/cr400195e"},{"key":"e_1_2_7_19_2","doi-asserted-by":"publisher","DOI":"10.1039\/C5CS90028J"},{"key":"e_1_2_7_20_2","doi-asserted-by":"publisher","DOI":"10.1126\/science.1205962"},{"key":"e_1_2_7_21_1","doi-asserted-by":"publisher","DOI":"10.1002\/anie.201106767"},{"key":"e_1_2_7_21_2","doi-asserted-by":"publisher","DOI":"10.1002\/ange.201106767"},{"key":"e_1_2_7_22_1","unstructured":"\u00a0"},{"key":"e_1_2_7_23_2","doi-asserted-by":"publisher","DOI":"10.1021\/acs.chemrev.6b00160"},{"key":"e_1_2_7_24_2","doi-asserted-by":"publisher","DOI":"10.1039\/C6CC01983H"},{"key":"e_1_2_7_25_1","unstructured":"\u00a0"},{"key":"e_1_2_7_26_2","doi-asserted-by":"publisher","DOI":"10.1021\/ar7000364"},{"key":"e_1_2_7_27_2","doi-asserted-by":"publisher","DOI":"10.1021\/acs.accounts.6b00042"},{"key":"e_1_2_7_28_2","doi-asserted-by":"publisher","DOI":"10.1021\/acs.chemrev.5b00188"},{"key":"e_1_2_7_29_2","doi-asserted-by":"publisher","DOI":"10.1039\/c2cs35156k"},{"key":"e_1_2_7_30_2","doi-asserted-by":"crossref","unstructured":"B.
