"space-inversion symmetry-breaking spin-orbit coupling... material need not be inherently magnetic...  valence band spin texture tunable by changing chirality of metal-organic backbone... 5 elements for obtaining large R-D spin splitting in 2D COMFs: (i) chirality, (ii) large spin–orbit coupling, (iii) narrow band gap, (iv) valence and conduction bands having the same symmetry at the Г point, and (v) strong ligand field... electric field-controlled spintronics... future: 2D R–D semiconductors with giant spin splitting"
