Effect of scaffold structures on the artificial light-harvesting systems: a case study with an AIEE-active pillar[5]arene dyad.

Artificial light-harvesting systems were assembled as nanoparticles by an AIEE-active pillar[5]arene dyad H1, a complimentary fluorescent ditopic guest G2, and an optically silent tritopic guest G1 in water with CTAB. The formation of H1-G1 supramolecular polymers enhanced the G2 emission and the H1-G2 energy transfer, confirming the importance of scaffold structures in the systems.
