Photocatalytic hydrogen production via water splitting is the subject of intense research. Photoinduced electron transfer (PET) between a photosensitizer (PS) and a proton reduction catalyst is a prerequisite step and crucial to affecting hydrogen production efficiency. Herein, three photoactive metal–organic framework (MOF) systems having two different PET processes where PS and Co(II) centers are...
Neuromorphic Imaging Systems
In article number 2206181, Xiaoli Zhao, Qingxin Tang, and co‐workers present a multimodal‐synergistic‐modulation neuromorphic imaging systems based on ultraflexible synaptic transistors. The device is capable to simulate the spherical structure and the environmental adaptive behavior of the human eye. Based on the function that synaptic weight can be synergistically regulated...
Inspired by human eyes, the neuromorphic visual system employs a highly efficient imaging and recognition process, which offers tremendous advantages in image acquisition, data pre‐processing, and dynamic storage. However, it is still an enormous challenge to simultaneously simulate the structure, function, and environmental adaptive behavior of the human eye based on one device. Here, a multimodal‐synergistic‐modulation...
Fine‐tuning the crystallinity and self‐aggregation features of donors/acceptor materials toward high‐efficiency organic solar cells (OSCs) is of crucial importance. Here, a convenient yet effective way to simultaneously control the crystallinity and self‐aggregation of the fused ring electron acceptor (FREA) is demonstrated by altering the length of the first‐position branched alkyl chain on the cyclic...
Discovering new drugs and improving action mechanisms is a promising strategy to overcome chemotherapy ineffectiveness caused by cancer cell apoptosis resistance. Natural products (like cyclic lipopeptides, CLPs) are potential sources of nonapoptotic cell death inducers and can form diverse supramolecular structures, closely relating to their bioactivities. Herein, it is found for the first time that...
Ultrathin organic thin‐film transistors (OTFTs) have received extensive attention due to their outstanding advantages, such as extreme flexibility, good conformability, ultralight weight, and compatibility with low‐cost and large‐area solution‐processed techniques. However, compared with the rigid substrates, it still remains a challenge to fabricate high‐performance ultrathin OTFTs. In this study,...
In article number 1801020, Qingxin Tang, Yichun Liu, and co‐workers achieve a high‐performance ultrathin organic thin‐film transistor (OTFT) array via a simple solution process, with the highest mobility of 11 cm2 V−1 s−1. The ultrathin thickness and ultralight weight enable the OTFTs to show good electrical characteristics when conformed onto different curved surfaces and even folded in a book. These...
In recent years, rapid advances are achieved in polymer solar cells (PSCs) using nonfullerene small molecular acceptors. However, no research disclosing the influence of molecular weight (Mn) of conjugated polymer on the nonfullerene device performance is reported. In this work, a series of polymers with different Mns are synthesized to systematically investigate the connection between Mn and performance...
