Visual Chiral Recognition through Enantioselective Metallogel Collapsing: Synthesis, Characterization, and Application of Platinum–Steroid Low‐Molecular‐Mass Gelators

Seeing is believing: The visual chiral recognition of (R)- and (S)-binap has been realized through an enantioselective breakdown of metallogels prepared from novel aromatic–linker–steroidal-type pincer platinum gelators. Van der Waals interactions, π stacking, and metal–metal bonding are responsible for the aggregation and chiral recognition.
