Hybridized Host Functions in Polyaromatic Tube-in-Capsule Composites.

ABSTRACT: Noncovalent hybridization of two types of host compounds has emerged as a promising strategy to develop unique functions, unattainable by either of the hosts. Here we report unusual spectroscopic features observed within a new hybrid host, formed by the combination of a polyaromatic tube and capsule, with rigid and flexible frameworks, respectively, in water. The resultant tube-in-capsule host selectively encapsulates rod-like aromatic dyes (e.g., BODIPY and coumarin derivatives), yielding ternary host-guest composites bearing a dye-in-tube structure. The ternary composites exhibit strong emission (up to Φ_F = ∼60%) from the bound dyes in water, with up to 45-fold enhancement compared to the corresponding dye-in-capsule composites, due to the spatial isolation of the dyes in the
