3+ hour, 30+ min ago  (430+ words) Chemistry Views Fr'd'ric Taran, SCBM " Universit' Paris Saclay, Gif-sur-Yvette, France, and colleagues have renewed attention to a long-overlooked class of mesoionic heterocycles: 3-aminosydnones. The team developed a scalable synthesis of a key 3aminosydnone building block bearing an exocyclic NH" group and…...

3+ mon, 2+ week ago  (333+ words) Chemistry Views Polyoxometalates (POMs) are valued for their remarkable structural diversity, nanoscale dimensions, and rich redox chemistry. Their niobium-based relatives, polyoxoniobates (PONbs), are more difficult to synthesize. Yet these materials are particularly attractive because of their high stability and strong…...

3+ mon, 3+ week ago  (267+ words) Chemistry Views Soressa Abera Chala and Carsten Streb, Johannes Gutenberg University Mainz, Germany, Bing Joe Hwang, National Taiwan University of Science and Technology, Taipei, Taiwan and National Synchrotron Radiation Research Center (NSRRC), Hsinchu, Taiwan, and colleagues have developed a hybrid…...

3+ mon, 3+ week ago  (178+ words) Chemistry Views HCY-3 was designed as a hemicyanine dye (HCY) with hydroxyl donor groups to promote hydrogen bonding. Comparisons with structural variants (S-HCY-1, HCY-4, and HCY-9) confirmed that molecular planarity and donoracceptor alignment are critical for J-aggregation (the ordered head-to-tail…...

3+ mon, 4+ week ago  (150+ words) Neil K. Garg, University of California, Los Angeles, USA, and colleagues have used highly strained alkenes'cubene and 1, 7-quadricyclene'to provide a straightforward way to build highly complex, three-dimensional molecules of interest to medicinal chemists. Alkene carbons are typically trigonal planar, as in…...

4+ mon, 4+ hour ago  (410+ words) Chemistry Views High-lying triplet emission generally follows two pathways: - Independent T" emission: The high-lying triplet state (T") emits without relying on T" (low-lying triplet state), requiring a large energy gap between T" and T" and a radiative transition rate of…...

4+ mon, 3+ day ago  (671+ words) Chemistry Views Sergey V. Kolotilov, National Academy of Sciences of Ukraine, Kyiv, Ukraine, and his colleagues wanted to understand how copper and carbon components contribute to the catalytic synthesis of fused pyridines. The central challenge was to determine whether Cu is…...
