The intrinsic helical π-conjugated skeleton makes helicenes highly promising for circularly polarized electroluminescence (CPEL). Generally, carbon undergo low external quantum efficiency (EQE), while the incorporation of a multi-resonance thermally activated delayed fluorescence (MR-TADF) BN structure has led to an improvement. However, reported B,N-embedded all show dissymmetry factors (g
Although the chemistry of macrocyclic arenes has seen rapid development in recent years, synthesis new from aromatic rings with no directing groups remains a challenge. In this work, arene, naphth[4]arene (NA[4]A), composed four naphthalene bridged by methylene groups, was synthesized using macrocycle-to-macrocycle conversion. NA[4]A shows 1,3-alternate and 1,2-alternate conformations solid state, which can be selectively obtained. By supramolecular co-assembly 1,2,4,5-tetracyanobenzene...
The strategy of integrating conformational isomerization donors and chiral acceptors in a single molecule was proposed to construct white circularly polarized luminescence (WCPL) materials this work. Consequently, pair dual-emission enantiomers, namely (R/S)-DO-PTZ, were designed synthesized, which displayed emission with blue yellow bands solution solid films Commission Internationale de l'Eclairage (CIE) coordinates (0.30, 0.33) (0.33, 0.35), respectively. Meanwhile, (R/S)-DO-PTZ exhibited...

Abstract Chirality‐driven self‐sorting plays an essential role in controlling the biofunction of biosystems, such as chiral double‐helix structure DNA from self‐recognition by hydrogen bonding. However, achieving precise control over self‐sorted structures and their functional properties for bioinspired supramolecular systems still remains a challenge, not to mention realizing dynamically reversible regulation. Herein, we report unprecedented saucer[4]arene‐based charge transfer (CT)...
A pair of multi‐emission enantiomers, (R)‐DO‐PSeZ and (S)‐DO‐PSeZ, was designed synthesized by integrating Se‐induced conformationally isomeric donors with a chiral carbonyl‐containing acceptor into unified molecular framework.

Two-proton relative momentum (qpp) and opening angle (θpp) distributions from the three-body decay of two excited proton-rich nuclei, namely Al23→p+p+Na21 Mg22→p+p+Ne20, have been measured with projectile fragment separator (RIPS) at RIKEN RI Beam Factory. An evident peak qpp∼20 MeV/c as well a in θpp around 30° are seen two-proton break-up channel highly-excited 22Mg. In contrast, such peaks absent for 23Al case. It is concluded that emission mechanism 22Mg quite different case, former...

Macrocycle-to-macrocycle conversion is an effective strategy to construct new macrocyclic arenes with specific structures. Herein, a class of chiral arene, namely, octopus[5]arenes (Oc5s), cannot be synthesized by the direct approach from corresponding monomers but can successfully achieved macrocycle-to-macrocycle utilizing racemic pagoda[5]arenes as starting materials. It was found that enantiomeric Oc5s showed fixed conformations and stable structures exhibited significant recognition...
