Two-dimensional (2D) room-temperature chiral multiferroic and magnetic topological materials are essential for constructing functional spintronic devices, yet their number is extremely limited. Here, by using the polar HPP (HPP = 4-(3-hydroxypyridin-4-yl)pyridin-3-ol) as an organic linker transition metals (TM Cr, Mo, W) nodes, we predict a class of 2D TM(HPP)2 organometallic nanosheets that incorporate homochirality, magnetism, ferroelectricity, nodes. The homochirality introduced linkers, change in structural chirality induces phase Weyl phonons. magnetism arises from strong d-p spin coupling between TM cations doublet anions. ferroelectricity attributed to breaking spatial inversion symmetry lattice structure. Additionally, adjusting type TMs, these show rich tunable band structures. Notably, all predicted topologically nontrivial, featuring quadratic nodal point around Fermi level.

Ground-state charge transfer plays a vital role in improving the photocatalytic performance of D-A type covalent organic frameworks. However, limited studies have explored modulation COFs-based photocatalysts through ground-state transfer. Here we show formation extremely intense via unique bonding approach. We transform three-dimensional stacked COF-based S-scheme heterojunctions (FOOCOF-PDIU) into co-planar single-molecule junctions (FOOCOF-PDI). This junction structure exhibits strong compared to traditional randomly and individual COFs. induces redistribution dipole moment formation, which enhances built-in electric field intensity junctions. enhanced promotes exciton dissociation separation, resulting improved efficiency.
