The team developed a scalable synthesis of a key 3aminosydnone building block bearing an exocyclic NH" group and…...

5+ mon, 4+ day 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…...

5+ mon, 2+ 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…...

5+ mon, 2+ 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…...
