However, its application in the synthesis of well-defined nanomaterials remains very limited. Here, we report a new bottom-up mechanochemical strategy to rapid mild-conditions synthesis of organic ligand-coated ZnO nanocrystals (NCs) and their further host\u2013guest modification with \u03b2-cyclodextrin (\u03b2-CD) leading to water-soluble amide-\u03b2-CD-coated ZnO NCs. The transformations can be achieved by either one-pot sequential or one-step three-component process. The developed bottom-up methodology is based on employing oxo-zinc benzamidate, [Zn<sub>4<\/sub>(\u03bc<sub>4<\/sub>-O)(NHOCPh)<sub>6<\/sub>], as a predesigned molecular precursor undergoing mild solid-state transformation to ZnO NCs in the presence of water in a rapid, clean and sustainable process.<\/p>\n<p>&nbsp;<\/p>\n<p style=\"text-align: center;\"><img decoding=\"async\" class=\"aligncenter wp-image-2004\" src=\"http:\/\/lewin.ch.pw.edu.pl\/wp-content\/uploads\/2016\/05\/ChEJ2016ZnO-CD.png\" alt=\"chej2016_ZnO-CD\" width=\"720\" \/><\/p>\n<p><a href=\"http:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/chem.201600182\/full\" target=\"_blank\">Paper on the Wiley Online Library website<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Chemistry, a European Journal, 2016, 22, 7817\u20137823. &nbsp; Applying mechanochemistry for bottom-up synthesis and host-guest surface modification of semiconducting nanocrystals: A case of water-soluble \u03b2-cyclodextrin-coated zinc oxide Piotr Krupi\u0144ski,a Arkadiusz Kornowicz,b Kamil Soko\u0142owski,aAnna Maria Cie\u015blak,a Janusz Lewi\u0144ski,ab a\u00a0Institute of Physical Chemistry, Polish Academy of Sciences, Kasprzaka 44\/52, 01-224 Warsaw, Poland b\u00a0Faculty of Chemistry, Warsaw University [&hellip;]<\/p>\n","protected":false},"author":2,"featured_media":3989,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"inline_featured_image":false,"footnotes":""},"categories":[19],"tags":[],"class_list":["post-3983","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-paper"],"_links":{"self":[{"href":"https:\/\/lewin.ch.pw.edu.pl\/index.php?rest_route=\/wp\/v2\/posts\/3983","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/lewin.ch.pw.edu.pl\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/lewin.ch.pw.edu.pl\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/lewin.ch.pw.edu.pl\/index.php?rest_route=\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/lewin.ch.pw.edu.pl\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=3983"}],"version-history":[{"count":20,"href":"https:\/\/lewin.ch.pw.edu.pl\/index.php?rest_route=\/wp\/v2\/posts\/3983\/revisions"}],"predecessor-version":[{"id":4024,"href":"https:\/\/lewin.ch.pw.edu.pl\/index.php?rest_route=\/wp\/v2\/posts\/3983\/revisions\/4024"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/lewin.ch.pw.edu.pl\/index.php?rest_route=\/wp\/v2\/media\/3989"}],"wp:attachment":[{"href":"https:\/\/lewin.ch.pw.edu.pl\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=3983"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/lewin.ch.pw.edu.pl\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=3983"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/lewin.ch.pw.edu.pl\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=3983"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
