Abstract
Organic chiral materials have brought attention due to their potential application in the area of spin-optics and optoelectronics. Compared with traditional achiral materials, the chirality generated orbital angular momentum (CGO) is one of the key properties for chiral materials. Here, organic nanocrystals with chirality are fabricated to study the effect of the CGO on the magneto-optic coupling. The CGO affects spin states through spin–orbital coupling, which will suppress spin relaxation time to tens of picoseconds. Furthermore, spin states in chiral crystals will be further tuned by the external magnetic field to demonstrate the dependence of spin–photon coupling effects on the magnetic field.
