• • Stimuli-responsive folding enables reversible chiroptical switching with response times on the order of seconds to minutes, as demonstrated by solvent polarity and temperature changes that reshape hydrogen-bond networks; this reversibility is critical for dynamic optical data storage and sensing applications.
• • Host-guest and coordination interactions achieve cooperative chirality transfer with association constants typically in the range of 10^3–10^5 M^-1, enabling amplification of chiral asymmetry from molecular to supramolecular levels; this is essential for designing highly sensitive chiral sensors and asymmetric catalysts.
• • Halogen-bond driven modulation provides directional control over molecular helicity with bond energies of 10–40 kJ/mol, allowing programmable and predictable structural changes; this precision is advantageous for constructing photonic devices with tailored chiroptical responses.
• • Intrinsic structural adaptability, exemplified by ferrocenyl frameworks and peptide folding, enables autonomous response to environmental changes without external stimuli, with diastereomeric excess values up to 99% in certain designs; this self-contained responsiveness is promising for developing smart materials with built-in actuation and self-healing capabilities.
