This compound exhibits upconversion based on a two-photon absorption (TPA) process with a cross-section value of 70 GM together with emission of circularly polarized luminescence (CPL), showing a glum in the range of 10\u22123. This simple structure represents one of the scarce examples of purely organic compounds combining both TPA and CPL responses, together with large values of molar absorptivity and \ufb02uorescence quantum yield with<br \/>\nemission in the 500\u2013600 nm. Self-assembly induced by introduction of a poor solvent allows for a spectacular shift of the emission into the near-infrared (NIR, 650\u2013750 nm) by formation of well-de\ufb01ned rotationally displaced dimers. Therefore, we are here presenting a versatile platform whose optical properties can be simply tuned by self-assembly or by functionalization of the electron-de\ufb01cient aromatic core of PDIs.<br \/>\nKeywords: perylene diimide (PDI), electronic circular dichroism (ECD), circularly polarized uminiscence (CPL), two-photon absorption, non-linear emission<\/p>\n<p>[pdfjs-viewer url=&#8221;https%3A%2F%2Fwww.bihec.com%2Folisclarity%2Fwp-content%2Fuploads%2Fsites%2F7%2F2020%2F07%2Ffchem-08-00306.pdf&#8221; viewer_width=100% viewer_height=1360px fullscreen=true download=true print=true]<\/p>\n<br><div class=\"tagcloud\"><\/div>","protected":false},"excerpt":{"rendered":"<p>In this work we describe the linear and non-linear (chiro)optical properties of an enantio <\/p>\n","protected":false},"author":7,"featured_media":14069,"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\/14067"}],"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\/7"}],"replies":[{"embeddable":true,"href":"https:\/\/www.bihec.com\/olisclarity\/wp-json\/wp\/v2\/comments?post=14067"}],"version-history":[{"count":2,"href":"https:\/\/www.bihec.com\/olisclarity\/wp-json\/wp\/v2\/posts\/14067\/revisions"}],"predecessor-version":[{"id":14072,"href":"https:\/\/www.bihec.com\/olisclarity\/wp-json\/wp\/v2\/posts\/14067\/revisions\/14072"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.bihec.com\/olisclarity\/wp-json\/wp\/v2\/media\/14069"}],"wp:attachment":[{"href":"https:\/\/www.bihec.com\/olisclarity\/wp-json\/wp\/v2\/media?parent=14067"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.bihec.com\/olisclarity\/wp-json\/wp\/v2\/categories?post=14067"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.bihec.com\/olisclarity\/wp-json\/wp\/v2\/tags?post=14067"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
