| Abstract |
For practical applications, molecular light-emitters should operate in solid-state device settings. Strong interchromophore interactions between closely stacked molecules, however, often perturb their intrinsic photophysics. To control three-dimensional molecular packing in the solid state, we have devised a propeller-shaped triazole derivative. Through efficient C-N cross-coupling reactions, this triazoliptycene motif could readily be installed on a wide range of halo(hetero)arenes to furnish fluorescent three-dimensional scaffolds. With multiple “de-stackers” supporting a rigid π-conjugated core, these molecules find the best compromise of π-π stacking and C-H…π interactions, but leave a void space when neither can be satisfied at intermolecular contacts in the solid-state. With appropriate structure design, unobstructed channels are thus created across the crystal lattice as potential sites for guest recognition and sequestration. In this presentation will be discussed key design principles and practical implementations of the new iptycene chemistry that we are currently exploring. |
