AI Article Synopsis
- Confined supramolecular architectures involving chromophores play a crucial role in the creation of artificial antenna composites for collecting and storing solar energy.
- The molecular mechanism underlying the insertion of dye molecules, specifically perylene diimide dyes, into zeolite channels remains unclear.
- The study reveals that the slipping and movement of these dyes within the zeolite L channels are facilitated by interactions between the host and guest molecules, alongside a uniquely structured channel that promotes self-assembly.
Article Abstract
Confined supramolecular architectures of chromophores are key components in artificial antenna composites for solar energy harvesting and storage. A typical fabrication process, based on the insertion of dye molecules into zeolite channels, is still unknown at the molecular level. We show that slipping of perylene diimide dyes into the one-dimensional channels of zeolite L and travelling inside is only possible because of steric-interaction-induced cooperative vibrational modes of the host and the guest. The funnel-like structure of the channel opening, larger at the entrance, along with a directionally asymmetric entrance-exit probability, ensures a favorable self-assembly process of the perylene units.
