Ladderization: A Powerful Strategy for Controlling Supramolecular Helical Ordering, Amplifying Asymmetry, and Emerging and Enhancing Circularly Polarized Luminescence

Small, EarlyView.
π‐Conjugated chiral ladder polymers with enantiopure side groups exhibit helical ordering‐induced circularly polarized luminescence (CPL) in poor solvents and in the film state. Vapor‐annealed films show a particularly strong CPL with glum values of > 0.1. Blending chiral/achiral ladder polymers markedly amplifies the asymmetry in the film.

Easily Accessible and Up‐Scalable Aliphatic Bis‐Formamides with Afterglow Luminescence: Photoluminescence Properties and Applications

Small, EarlyView.
A bis formamide molecule was found to feature afterglow properties, in both crystalline powder state and in polyvinyl alcohol films. This was attributed to the intermolecular packing that allows H‐trapped emitting state and/or clustering‐triggered emission, which was intensified upon insertion of tetramethylbenzidine as a doping agent.

Revisiting face forgery detection towards generalization

Neural Networks
Face forgery detection aims to distinguish AI generated fake faces with real faces. With the rapid development of face forgery creation algorithms, a large number of generative models have been proposed, which gradually reduce the local distortion phenomenon or the specific frequency traces in these models. At the same time, in the process of face data
