Chiral supramolecular architectures deliver desired properties and functions to artificial systems. The recently developed direct circularly polarized light (CPL) detection is based on electronic devices with chiral active layers that inform photocurrent dissymmetry (g sc ) upon illuminations of opposing CPL. Due to limited absorption dissymmetry (g abs ) in the chiral active layers, exploring the prospect of creating additional g sc in chiral electronic devices is becoming increasingly relevant. In particular, rationalizing the corresponding amplification mechanisms is still challenging. Here, we achieve accurate CPL detection through an amplified g sc from bulk heterojunction (BHJ) small-molecule organic solar cells (OSCs) with supramolecular chirality. The alternating preferential and nonpreferential CPL illuminations cause a difference in maximum absorption position across the chiral active layer, resulting in differences in exciton separation and charge recombination, transport, and collection. These differences contribute to additional difference in photocurrent output and the amplified g sc in the chiral OSCs. From the perspective of device structure, our study likely provides insights into the amplified g sc in chiral electronic devices for direct CPL detection.

High‐performance organic semiconductor materials as the electroactive components of optoelectronic devices have attracted much attention and made them ideal candidates for solution‐processable, large‐area, and low‐cost flexible electronics. Especially, organic field‐effect transistors (OFETs) based on conjugated semiconductor materials have experienced stunning progress in device performance. To make these materials economically viable, comprehensive knowledge of charge transport mechanisms is required. The alignment of organic conjugated molecules in the active layer is vital to charge transport properties of devices. The present review highlights the recent progress of processing‐structure‐transport correlations that allow the precise and uniform alignment of organic conjugated molecules over large areas for multiple electronic applications, including OFETs, organic thermoelectric devices (OTEs), and organic phototransistors (OPTs). Different strategies for regulating crystallinity and macroscopic orientation of conjugated molecules are introduced to correlate the molecular packing, the device performance, and charge transport anisotropy in multiple organic electronic devices.

Owing to the complex and long-term treatment of foot wounds due to diabetes and the limited mobility of patients, advanced clinical surgery often uses wearable flexible devices for auxiliary treatment. Therefore, there is an urgent need for self-powered biomedical devices to reduce the extra weight. We have prepared an electrically stimulated MEMS (Micro Electromechanical System) electrode integrated with wearable OPV (Organic photovoltaic). The wearable OPV is constructed of a bio-affinity PET-ITO substrate and a hundred-nanometer organic layer. Under sunlight and near-infrared light irradiation, a voltage and current are supplied to the MEMS electrode to generate an exogenous lateral electric field directed to the center of the wound. The results of in vitro cell experiments and diabetic skin-relieving biological experiments showed the proliferation of skin fibroblasts and the expression of transforming growth factors increased, and the skin wounds of diabetic mouse healed faster. Our research provides new insights for the clinical treatment of diabetes.
