Abstract
Disclosed are a small-molecule electron donor material with an electron-deficient heterocyclic core, preparation and application thereof, belonging to technical field of solar cells. According to the present application, a brand-new electron-deficient heterocyclic unit which has never been applied to an organic solar cell is used as a core unit to prepare a small-molecule electron donor material with an A-D-A′-D-A skeleton structure, and the molecular structure of the small-molecule electron donor material is shown in formula (I).
