Electrostatic gating directly manipulates the electronic flat bands and van Hove singularities in single-layer molecular kagome lattices, enabling unprecedented control over quantum phenomena in 2D materials.

Breaking inversion symmetry is normally assumed to unleash even-order optical responses, but hidden bipartite particle-hole symmetry can suppress them entirely—unlocking photo-induced, pure spin currents with virtually no parasitic charge flow.
