WebFeb 23, 2001 · Nanoparticles of the molecular crystal naphthalene were prepared through a solvent exchange process. The gradual replacement of the solvent acetone with water induces aggregation and precipitation of naphthalene. Near the phase boundary in this ternary system we found regions in which nanocrystals with diameters on the order of … WebMar 1, 2024 · However, the boron difluoride chelated NIPBF–Br is twist, and angle between pyridine and naphthalene core is about 17.33°. The crystal structure of NIP–Br/NIPBF–Br co-crystals have revealed the structural characteristics of boron difluoride chelated naphthalene imide for the first time.
