Metal-Free Benzothioxanthene Imide Based Dyes for Yellow to Green Emitting Electrochemical Cells |
| 초록 |
Organic light emitting electrochemical cells (OLECs) have been widely explored due to its easy fabrication and simple processibility. In this study, OLEC device incorporating, for the first time, benzothioxanthene imide (BTI) derivatives were demonstrated. Impact of subtle chemical modifications on the Π-conjugated backbone on the optical, electrochemical and self-assembly properties were investigated and rationalized to device performances. Depending on the functionalization, high luminescence (~3900cd/m2) and stability were achieved once blended with host polymers such as polyvinylcarbazole (PVK) and polydioctylfluorene (PFO) owing to efficient energy transfer and suppressed luminescence aggregation caused quenching (ACQ). These results thus highlight the great potential of this new class of metal-free dye for OLECs while opening doors to new design principles and advanced device engineering. |
