Quantum materials require stringent control over electron spins to demonstrate unique quantized states capable of developing ground-breaking electromagnetic-signal processing, sensing, and detecting capabilities. Conventionally, electron spins with nanoscale and 2D-surface designs have been used as the primary approach to develop quantum materials. Recently, optically addressable circularly polarized orbital spins capable of spin-up and spin-down states have been demonstrated in organic chiral structures at room temperature. This work presents an unconventional approach of using orbital spins towards developing chiral organic donor-acceptor molecules with infrared sensing capabilities, as compared to conventional approach of using electron spins. Here, we also introduce chemical design strategies to control helicity and charge transfer that provide dipoles suitable for spin-orbital coupling.
