This is, to the best of our knowledge, the first undecabenzo[7]carbohelicene, i.e., the first fully \u03c0-extended [7]helicene. Racemic resolution allowed its chiroptical properties analysis revealing dissymmetry factors in the range of 2\u00d710-3 both in the absorption and in the emission measurements. Remarkably, nonlinear photophysical analysis showed two-photon absorption crosssection of 870 GM at 800 nm and a perfect overlapping between linear, non-linear and chiral emission.<\/div>\n<div><\/div>\n<div>URI:\u00a0<a href=\"http:\/\/hdl.handle.net\/10481\/52640\">http:\/\/hdl.handle.net\/10481\/52640<\/a><\/div>\n<div>DOI:\u00a0<a href=\"http:\/\/dx.doi.org\/10.1002\/anie.201808178\">10.1002\/anie.201808178<\/a><\/div>\n<\/div>\n<div class=\"simple-item-view-collections item-page-field-wrapper table\"><\/div>\n<div><img loading=\"lazy\" class=\"alignnone size-full wp-image-57\" src=\"https:\/\/www.bihec.com\/olisclarity\/wp-content\/uploads\/sites\/7\/2018\/07\/DSM-172-2-1.jpg\" alt=\"\" width=\"4256\" height=\"2832\" srcset=\"https:\/\/www.bihec.com\/olisclarity\/wp-content\/uploads\/sites\/7\/2018\/07\/DSM-172-2-1.jpg 4256w, https:\/\/www.bihec.com\/olisclarity\/wp-content\/uploads\/sites\/7\/2018\/07\/DSM-172-2-1-300x200.jpg 300w, https:\/\/www.bihec.com\/olisclarity\/wp-content\/uploads\/sites\/7\/2018\/07\/DSM-172-2-1-768x511.jpg 768w, https:\/\/www.bihec.com\/olisclarity\/wp-content\/uploads\/sites\/7\/2018\/07\/DSM-172-2-1-1024x681.jpg 1024w, https:\/\/www.bihec.com\/olisclarity\/wp-content\/uploads\/sites\/7\/2018\/07\/DSM-172-2-1-272x182.jpg 272w\" sizes=\"(max-width: 4256px) 100vw, 4256px\" \/><\/div>\n<br><div class=\"tagcloud\"><\/div>","protected":false},"excerpt":{"rendered":"<p>\u87ba\u65cb\u7eb3\u7c73\u77f3\u58a8\u5e26\u4f5c\u4e3aCPL\u5706\u504f\u632f\u53d1\u5149\u4f53 We report the synthesis and characterization of an enantiopure superhel <\/p>\n","protected":false},"author":1,"featured_media":13779,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":[],"categories":[1],"tags":[],"_links":{"self":[{"href":"https:\/\/www.bihec.com\/olisclarity\/wp-json\/wp\/v2\/posts\/13778"}],"collection":[{"href":"https:\/\/www.bihec.com\/olisclarity\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.bihec.com\/olisclarity\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.bihec.com\/olisclarity\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.bihec.com\/olisclarity\/wp-json\/wp\/v2\/comments?post=13778"}],"version-history":[{"count":1,"href":"https:\/\/www.bihec.com\/olisclarity\/wp-json\/wp\/v2\/posts\/13778\/revisions"}],"predecessor-version":[{"id":13780,"href":"https:\/\/www.bihec.com\/olisclarity\/wp-json\/wp\/v2\/posts\/13778\/revisions\/13780"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.bihec.com\/olisclarity\/wp-json\/wp\/v2\/media\/13779"}],"wp:attachment":[{"href":"https:\/\/www.bihec.com\/olisclarity\/wp-json\/wp\/v2\/media?parent=13778"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.bihec.com\/olisclarity\/wp-json\/wp\/v2\/categories?post=13778"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.bihec.com\/olisclarity\/wp-json\/wp\/v2\/tags?post=13778"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
