Light-controllable cucurbit[7]uril-based molecular shuttle

The design and construction of novel artificial molecular machines can be categorized as a currently important field of modern chemistry. In the present work, a novel photoresponsive [3]rotaxane containing two cucurbit[7]uril (CB[7]) rings and a dumbbell

With reversible photochromic performance of zinc complex single crystal and its preparation method (by machine translation)

The invention discloses a reversible photochromic zinc complex single crystal and its preparation method, which belongs to the technical field of complex chemical function. Such complexes to 1 - (3, 5 - dicarboxylic acid phenyl) - 4, 4' - bipyridyl chloride are respectively connected with the six hydrated zinc nitrate and zinc chloride prepared by the method by the solvent. Ligand 1 - (3, 5 - dicarboxylic acid phenyl) - 4, 4 '- bipyridyl chloride is to 5 - methyl 3, 5 - dicarboxylic acid and 4, 4' - bipyridyl as raw materials by esterification, bromo, pro-nuclear substituted, hydrolysis method synthesis; the two complexes of the present invention single crystal is 1 - (3, 5 - dicarboxylic acid phenyl) - 4, 4' - bipyridyl chloride or zinc chloride and zinc nitrate respectively in acetonitrile and water in the mixed solvent, in the 120 - 130 °C constant temperature for 3 days, then under natural conditions to the room temperature, to obtain the complex single crystal. The composition of the invention with reversible photochromic properties, ultraviolet radiation and heat treatment under the circumstances that the color of the reversible change, and can keep the crystal shape does not change.
