Abstract In this work, a noncoplanar terphenyl served as building block to synthesize novel 3,3′‐substituted bipyridyl ligand ( L1 ) which further reacted with binuclear half‐sandwich units A/B , giving rise two aesthetic 4 1 metalla‐knots in high yields via coordination‐driven self‐assembly strategy. Furthermore, given the inherent compactness of metalla‐knots, it creates favorable conditions for emergence steric repulsion. We focused on progressively introducing nitrogen atoms featuring lone pair electrons (LPEs) into manipulate balance H⋅⋅⋅H/LPEs⋅⋅⋅LPEs repulsion during assembly process, ultimately achieving controlled from pseudo ‐Solomon link and then molecular tweezer‐like facilitated by stacking interactions. All assemblies were well characterized solution‐state NMR techniques, ESI‐TOF/MS, single‐crystal X‐ray diffraction. The evolutionary process topological architectures is equivalent visualizing synergistic effect hindrance interactions structural assembly, providing new avenue synthesis different topologies.

Comprehensive Summary Traditional fluorescent probes typically display blueshifted emission in rigidifying media; however, a newly developed class of rigidochromic fluorophores derived from phenanthridine demonstrates remarkable redshifted under similar conditions. Pyridine, with N‐heterostructure to those group, is considered promising candidate for achieving comparable rigidity‐induced redshift behavior. In this work, we synthesized eight organic featuring diverse functional units and substitutes by systematically combining pyridine carbazole, triazatruxene (TAT), tetraphenylethylene (TPE), respectively. These molecules exhibit significant redshifts (up 225 nm, record high value ever reported) or notable intensity changes as the rigidity polymer matrix increases, along unique acid responsiveness. The differences polar‐π interactions between polymers diversify behavior, advancing development secure printing intelligent optical materials. By embedding these into films helical phase structures, tunable chirality was achieved. Notably, leveraging acid‐responsive properties fluorophores, time‐dependent light‐controlled dynamic encryption system constructed, successfully enabling multi‐level information encryption. This research greatly expands scope their applications anti‐counterfeiting storage.
