説明:

Boron nitride nanotubes (BNNTs) are used for the self-assembly of tetracene (Tc) molecules without chemical modification in their one-dimensional nanocavities. The Tc aggregated state can be changed depending on the encapsulated Tc amount that is controlled by the sublimation condition of Tc molecules for the complexation (Tc@BNNTs). As a result, the photophysical processes including singlet fission in the Tc assemblies are varied, which enables the emission mode switching of the aggregation-based fluorescence and the excimer emission for Tc@BNNTs. Consequently, the host–guest complexation using BNNTs allows not only the fabrication and evaluation of optically functionalized molecular assemblies in the nanocavity but also the modulation of their photophysical processes, by which the emission colors of Tc@BNNTs are also tuned.
