Electrochemically, the donor-chromophore (D-C) dyad and the donor-chromophore-acceptor (D-C-A) triad exhibit both metal-based and donor ligand-based oxidations, whereas the triad and the C-A dyad show the expected pyridinium- and terpyridine-based reductions. Transient absorption studies of the dyad and triad systems indicate that although the trimethoxybenzene group acts as a reductive donor, in the
V-shaped monomer derived from BODIPY has been shown to self-assemble in non-polar media into anticooperatively formed luminescent oligomers with ultrahigh thermal stability. The delicate balance between attractive interactions (unconventional C/N−H⋅⋅⋅F−B hydrogenbonds), steric side chain effects, and inefficient aromatic interactions associated with the non-preorganized V-shaped monomer geometry lead
来自 BODIPY 的 V 形单体已被证明可以在非极性介质中自组装成具有超高热稳定性的抗合作形成的发光低聚物。有吸引力的相互作用(非常规 C/N−H⋅⋅⋅F−B 氢键)、空间侧链效应和与非预组织 V 形单体几何相关的低效芳族相互作用之间的微妙平衡导致离散生长受限低聚物堆。
