Synthesis and photothermal performance investigation of molecular-tweezer-like compound 1(OTf)8, snowflake-shaped folded assembly 2(OTf)12, 818 Knot 3(OTf)16 and closed three-link chain 4(OTf)12.

Caption

Two carbazole ligands L1, L2 possessing different angles were synthesized, which react with different building units endowed with specific dimension and conjugation, resulting in a molecular-tweezer-like compound, a snowflake-shaped folded assembly, an 818 knot and a closed three-link chain. The angle of ligand is the main reason for the formation of interlocking and non-interlocking structure. And the photothermal conversion studies displayed that closed three-link chain exhibited the highest conversion rate and significant cycling performance due to multiple stacking and the free radical effect of building unit.
