The solvent‐free organic π‐liquids have been attracting increasing attentions owing to the inherent optoelectronic properties accompanied by the advantages of non‐volatility and high processability. Herein, we reported a series of naphthalene derivatives substituted with chiral branched alkyl chains, which are present as liquids (Nap1–3) or solid (Nap4) at room temperature, depending on the substitution positions. Circular dichroism (CD) and circularly polarized luminescence (CPL) were only observed for enantiomeric Nap2 (2,3‐substituted) liquid. It is suggested that the chiral aggregation in the π‐liquid leads to the CD signal and the chiral excimer resulting in the CPL performance. When achiral anthracene or pyrene was dissolved in Nap2, the π‐liquid could serve as chirality and energy transfer media in which both CD and CPL emerged from the achiral anthracene. A CPL dissymmetry factor (|glum|) of anthracene reached to 5.2×10−2 when dissolved in chiral Nap2 liquid, which is nearly two orders of magnitude higher than that of the pure Nap2 π‐liquid.

Coordination is an important factor that can be used to modulate the structure and function of self‐assembly systems. Herein, we report the coordination‐regulated self‐assembly of chiral nanostructures and their enantioselective catalytic performances. We found that if a rhodium complex and an l‐glutamic acid terminated bolaamphiphile were self‐assembled by coordination, single‐walled nanotubes and nanospheres could be obtained depending on the molar ratio. Interestingly, the nanotubes and nanospheres showed opposite supramolecular chirality even though the same chiral bolaamphiphile was used. If the nanospheres and nanotubes were used as catalysts for the asymmetric cyclopropanation reaction, opposite enantioselectivities were obtained, which indicated that it was the supramolecular chirality rather than the molecular chirality that controlled the enantioselectivity of the asymmetric reaction. This work provides not only a feasible method to construct different nanostructures through metal coordination but also a new pathway of transferring chirality from the supramolecular level to chiral products.

The behavior of six systems of graphite with Sn, Pb, Sb, Bi, Se, and Te was investigated under high-pressure of around 9.0–9.6 GPa and high-temperature 1600–1850 °C. The results showed that the selenium and tellurium have obvious catalytic effects on spontaneous nucleation and crystal growth of diamond under pressure at 9.6 GPa, and at temperatures of 1800 and 1850 °C. The outer shell electron configuration analogous to oxygen and sulfur may play an important role in converting graphite to diamond under the high-pressure and high-temperature.
