Materials Synthesis


Organic semiconductors are the heart of all organic electronic devices. In ORaCEL, we are committed to designing and synthesizing materials with desired optoelectronic properties. You research group at UNC-Chapel Hill excels in synthesizing various conjugated polymers. In particular, the donor-acceptor polymer PBnDT-FTAZ (See Schematic) has successfully been used to develop organic solar cells with efficiency exceeding 12%.

ORaCEL research also focuses on synthesizing organic small molecules, quantum dots, and perovskites for various applications. Typical examples include a synthesis of uniquely defined quantum dot and surface-anchored molecular acceptors for realizing the transfer of triplet exciton energy. This work was recently reported by Castellano research group in Science.
