Summary: Researchers have designed a new type of peptide nanomaterial consisting solely of histidine and tyrosine residues, which exhibit biocompatible amyloid-like fibrils and hydrogels with hydrolytic and electrocatalytic activities. These nanofibers show controllable mesoscopic properties at different pH levels, transitioning between active beta-sheet fibrils and inactive random coil species. The structural insights derived from molecular dynamic simulations offer understanding on how these amyloid-like fibrils achieve a combination of structural and catalytic properties.

Summary: This study successfully prepared metal-organic frameworks (MOFs) with high photocurrent performance by tuning the size and topology of the MOFs. The structural adjustment of the auxiliary ligands plays an important role in determining the size and dimensions of the MOFs, with rod-shaped auxiliary ligands leading to better three-dimensional extension and fold-like auxiliary ligands enabling two-dimensional extension. Moreover, the study found that the fold-like auxiliary ligand can greatly enhance the photocurrent intensity of the MOFs, achieving nearly 10 times higher intensity than the traditional TTF unit.

Summary: Several thiophene terminated thienoacenes with different alkylation positions on the terminal thiophene rings were synthesized and characterized. The molecular stacking and physicochemical properties were found to be effectively tuned by the alkylation. The OTFTs based on 2,8-dioctyl-naphtho[2,3-b:6,7-b '] bithieno [2,3-d] thiophene (2,8-C8NBTT) exhibited the highest mobility of 3.58 cm2 V-1 s-1 and a remarkably high current on/off ratio. Furthermore, the organic phototransistors based on 2,8-C8NBTT demonstrated higher photosensitivity, photoresponsivity, and detectivity compared to the other derivatives NBTT and 3,9-dioctyl-naphtho[2,3b:6,7-b '] bithieno [2,3-d] thiophene (3,9-C8NBTT).
