Sandwich-like heterochromophore metallo-supramolecules based on dense chromophore arrangements with energy and chirality transfer properties
Multichromophoric architectures with well-organized chromophoric arrangements are of vital importance to gain insights into interchromophoric interactions. Herein, we report a novel heteroleptic self-assembly strategy and construct three achiral and one chiral sandwich-like heterochromophore complex...

| description | Multichromophoric architectures with well-organized chromophoric arrangements are of vital importance to gain insights into interchromophoric interactions. Herein, we report a novel heteroleptic self-assembly strategy and construct three achiral and one chiral sandwich-like heterochromophore complexes (Zn4LGLA-C2 and Zn4LGLD2). Possible dynamic products, including homoleptic oligomers and isomers, are eliminated, producing achiral complexes with exceptional purity. Isomers are observed in chiral complexes due to the flexible geometry of LD. Perfectly aligned chromophore arrangements with precise spacing and orientations are evidenced by single-crystal X-ray diffraction. The distinct segments in the ligands lead to different interchromophoric interactions. Impressively, energy transfer and tunable emission, including white-light emission, are achieved for Zn4LGLA2 and Zn4LGLB2. In addition, chirality transfer is observed for Zn4LGLD2, due to conformational restriction from chiral LD, leading to chiral rotational conformations of tetraphenylethylene moiety in LG |
