The cooperativity in artificial self-assembling systems can be enhanced to expand their applications and redesign properties. Recently, chiral molecules have garnered renewed attention due potential as highly efficient spin filters through the chiral-induced selectivity (CISS) effect. However, of asymmetric building blocks based on perylene diimides (PDIs) self-assembled materials generate a spin-polarized current is still not widely acknowledged. In this work, we demonstrated that nanofibers derived from "asymmetric PDIs" been found exhibit promising spin-filtering property amplification polarization at room temperature.

Abstract We present the first investigation of unusual nonlinear Hall effects in twisted multilayer 2D materials. Contrary to expectations, our study shows that these are not merely extensions their monolayer counterparts. Instead, we find stacking order and pairwise interactions between neighboring layers, mediated by Berry curvatures, play a pivotal role shaping collective optical response. By combining large-scale Real-Time Time-Dependent Density Functional Theory (RT-TDDFT) simulations with model Hamiltonian analyses, demonstrate remarkable second-harmonic transverse response hexagonal boron nitride four-layers, even cases where total curvature cancels out. Furthermore, symmetry analysis layered structures provides simplified framework for predicting responses materials general. Our challenges prevailing understanding opens new avenues design development advanced tailored properties.
