A Supramolecular Double-Cable Structure With A 12944 Helix In A Columnar Porphyrin-C60 Dyad And Its Application In Polymer Solar Cells, Xiong Gong
Xiong Gong
A novel porphyrin-C60 dyad (PCD1) is designed and synthesized to investigate and manipulate the supramolecular structure where geometrically isotropic [such as [60]fullerene (C60)] and anisotropic [such as porphyrin (Por)] units coexist. It is observed that PCD1 possesses an enantiomeric phase behavior. The melting temperature of the stable PCD1 thermotropic phase is 160 °C with a latent heat (ΔH) of 18.5 kJ mol−1. The phase formation is majorly driven by the cooperative intermolecular Por–Por and C60–C60 interactions. Structural analysis reveals that this stable phase possesses a supramolecular “double-cable” structure with one p-type Por core columnar channel and three helical n-type C60 …
