title = "Study on synthesis and photophysical properties of a small molecule donor material containing alkyl selenophenyl side chains",
abstract = "The efficiency of Organic Solar Cells (OSCs) based on polymer donors and Non-Fullerene Acceptors (NFAs) is close to 20\%. However, compared with polymer donors, Small Molecule Donors (SMDs) have the advantages of molecular structure determination and easy purification. Through replacing the sulfur atom on the solubilized side chain of small molecule donor of B1 with the selenium atom, the molecule BSeEH has been designed and synthesized. Compared with B1, the crystallinity of BSeEH was significantly enhanced, and the intermolecular interaction force was improved. And the absorption spectrum of the BSeEH undergoes a blue shift, indicating that the molecular band gap has been widened. The variation in absorption spectra indicates that BSeEH has the potential to become an efficient small molecule donor material.",
