Magnetoelectric (ME) multiferroic materials have unique advantages in low-power and high-density information storage, because they can simultaneously display ferroelectricity and ferromagnetism. However, research on how to construct air-stable high-performance ME single-molecule magnets (SMMs) is nonexistent. Herein, by introducing homochirality while reducing molecular symmetry, two double-decker Dy(III) enantiomers adopting the polar space group P2₁ and exhibiting excellent thermal stability were obtained. They displayed zero field SMM behavior with an anisotropy barrier (Ueff) of ca. 100 cm⁻¹. This work establishes a rational chemical design strategy for crystallizing SMMs in polar space groups and elucidates the direction for future research, that is, engineering small-size high-performance SMMs.
