Anticooperative Supramolecular Oligomerization Mediated by V‐Shaped Monomer Design and Unconventional Hydrogen Bonds

Abstract: After more than three decades of extensive investigations on supramolecular polymers, strategies for self‐limiting growth still remain challenging. Herein, we exploit a new V‐shaped monomer design to achieve anticooperatively formed oligomers with superior robustness and high luminescence. In toluene, the monomer‐oligomer equilibrium is shifted to the monomer side, enabling the elucidation of the molecular packing modes and the resulting (weak) anticooperativity. Steric effects associated with an antiparallel staircase organization of the dyes are proposed to outcompete aromatic and unconventional B−F⋅⋅⋅H−N/C interactions, restricting the growth at the stage of oligomers. In methylcyclohexane (MCH), the packing modes and the anticooperativity are preserved; however, pronounced solvophobic and chain‐enwrapping effects lead to thermally ultrastable oligomers. Our results shed light on understanding anticooperative effects and restricted growth in self‐assembly.
