Description | We are developing a range of conjugated molecules and polymers with terminal functional group for single molecule spectroscopy. The results show how the structure and processing of organic semiconductors affect their performance in solar cells. A particularly interesting finding was the use of a "templating additive" as a way of improving bulk heterojunction morphology and device performance. That polymers can be studied at the single chain level and the methodology has been established and demonstrated. We will disseminate key findings at meetings such as conferences. A key paper is currently under review that identifies control of the beta-phase in a single polymer chain |
Exploitation Route | Manipulation of conformation and morphology can be controlled and this will be of particular interest to those working in the area of organic semiconductors and processing. |

Title | Effect of end group functionalisation of small molecules featuring the fluorene-thiophene-benzothiadiazole motif as emitters in solution-processed red and orange organic light-emitting diodes |
Description | A series of red fluorescent materials (compounds 1-4), which each contain the symmetric fluorene-thiophene-BT-thiophene-fluorene core, is presented along with their performance in solution-processed OLED devices. Extending the molecular conjugation through end-capping with additional fluorene units (compound 2), or through incorporation of donor functionalities (compounds 3 and 4) improves OLED performance relative to the parent compound 1. Notably, incorporating triphenylamine donor groups in compound 3 led to solution-processed OLED devices operating with a peak luminance of 2888 cd m-2 and a low turn-on voltage (3.6 V). |
