Bay-Substitution Effect on Supramolecular Chirality and Optoelectronic Properties of Self-Assembled Perylene Diimides |
| 초록 |
Here, we synthesized various bay-substituted chiral PDIs and self-assembled them into 1D nanomaterials. Each of the nanomaterials exhibited unique supramolecular chirality due to the bay-subsitution effect. Structural modification through the bay position also affect the electronic and optical properties. Among them, mono-cyanated NW based organic phototransistors exhibited the highest electron mobility up to 0.17 cm2 V−1s−1 and a low threshold voltage of −1 V. In addition, they showed outstanding optoelectronic performance with maximum photoresponsivity of 209 A W−1. Our results paved the way to utilize the bay substitution effect to tune the optoelectronic performance and supramolecular chirality effectively. |
