Table 1 and 2). By reduction of ketones II by sodium borohydride, we obtained methyl(IVa) and phenyl(IVb) [2,2]-paracyclophane-4-yl}carbinols having an asymmetric center and a plane of asymmetry for the monosubstituted para-cyclophane moiety. According to the PMR spectral data, mixtures of diastereomeric racemic alcohols IVa are obtained in an 1:2 ratio. The major diastereomer, which according to the

The first examples of through-space conjugated thermally activated delayed fluorescence (TADF) emitters based on a [2.2]paracyclophane (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.

multigram-scale and gives access to enantiomerically pure derivatives with planar and central chirality of (Rp)-4-acetyl-PCP (≥97% ee, 43%) and (Sp,S)-PCP derivatives (≥97% ee, 46%), which are useful intermediates for the synthesis of sterically demanding PCP-based ligand/catalyst systems and chiralsynthons for engineering cyclophane-based chiroptical materials.
