A long\u2010chain polyamine simultaneously mineralizes and assembles ZnO nanoparticles directly from water\u2010soluble zinc salts under sustainable synthesis conditions. These thus\u2010generated oriented structures undergo interesting morphogenesis that is controlled by changing the ratio of polyamine\/Zn\n                    <jats:sup>2+<\/jats:sup>\n                    ions. As the ratio increases, the morphology changes from a spherical shape to oval\u2010, dumbbell\u2010, and finally hexagonal\u2010rod\u2010shaped structures that contain unique hollow rod structures. Using XPS, XRD, FT\u2010IR, Raman spectroscopy, DLS, and confocal fluorescence microscopic analysis, we elucidate the mechanism of structural evolution; this mechanism involves the initial formation of a zinc\/amine complex that is furnished with polyamine chains. These chains facilitate the condensation process to form ZnO nanoparticles and their assembly in aqueous medium at neutral pH. Further, the presence of defects in the thus\u2010morphogenized ZnO structures leads to blue luminescence and efficient photoinduced activity, assisted by the surface\u2010hole\u2010trapping effect of polyamines.\n                  <\/jats:p>","DOI":"10.1002\/chem.201102473","type":"journal-article","created":{"date-parts":[[2011,12,14]],"date-time":"2011-12-14T07:52:05Z","timestamp":1323849125000},"page":"498-506","source":"Crossref","is-referenced-by-count":21,"title":["Oriented Morphogenesis of ZnO Nanostructures from Water\u2010Soluble Zinc Salts under Environmentally Mild Conditions and Their Optical Properties"],"prefix":"10.1002","volume":"18","author":[{"given":"Joydeb","family":"Manna","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rohit Kumar","family":"Rana","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2011,12,14]]},"reference":[{"key":"e_1_2_6_1_2","doi-asserted-by":"publisher","DOI":"10.1126\/science.1060367"},{"key":"e_1_2_6_2_2","doi-asserted-by":"publisher","DOI":"10.1002\/adfm.201002099"},{"key":"e_1_2_6_3_2","doi-asserted-by":"publisher","DOI":"10.1002\/adma.200306659"},{"key":"e_1_2_6_4_2","doi-asserted-by":"publisher","DOI":"10.1021\/am8000743"},{"key":"e_1_2_6_5_2","doi-asserted-by":"publisher","DOI":"10.1002\/chem.200903347"},{"key":"e_1_2_6_6_2","doi-asserted-by":"publisher","DOI":"10.1002\/chem.200903370"},{"key":"e_1_2_6_7_2","doi-asserted-by":"publisher","DOI":"10.1126\/science.1124005"},{"key":"e_1_2_6_8_2","doi-asserted-by":"publisher","DOI":"10.1002\/adma.201001289"},{"key":"e_1_2_6_9_2","doi-asserted-by":"publisher","DOI":"10.1021\/ja0279545"},{"key":"e_1_2_6_10_2","doi-asserted-by":"publisher","DOI":"10.1007\/s10971-010-2171-3"},{"key":"e_1_2_6_11_2","doi-asserted-by":"publisher","DOI":"10.1021\/cm0213725"},{"key":"e_1_2_6_12_2","doi-asserted-by":"publisher","DOI":"10.1021\/ja062434l"},{"key":"e_1_2_6_13_2","first-page":"20","volume":"1","author":"Chaudhuri T.
