Detailed Investigation of Light Induced Charge Injection into a Single Conjugated Polymer Chain |
| 초록 |
Detailed single molecule spectroscopic results are presented for the recently reported oxidation of single-chain conjugated polymers of MEH-PPV at the HTL/insulator interface of an MIS device. The charge injection process was determined to be light dominated with no charging occurring in the dark at any applied bias. The nature of the optical preparation of the injected charge is explored by a range of single molecule fluorescence voltage modulation techniques. The observed charging dynamics are highly consistent with a cooperative charging effect. It is also observed that analogous charing occurs for the conjugated polymer F8BT. The chargin/discharging dynamics were investigated indirectly by a variety of single molecule electro-optical spectroscopic techniques, including an "image-capture"approach. |
