I.D.W.S. also acknowledges support from a Royal Society Wolfson Research Merit Award.The first examples of through-space conjugated thermally activated delayed fluorescence (TADF) emitters based on a [2.2]para- cyclophane (PCP) skeleton with stacked (coplanar) donor-acceptor groups have been synthesized. The optoelectronic properties are studied by the relative configuration, cis (pseudo-geminal) and trans (pseudo-para), of the donor and acceptor groups.PostprintPeer reviewe
