- Abstract
Self-assembly of AgX (X- = BF4-, ClO4-, and NO3-) with C3-symmetric 1,3,5-tris(isonicotinoyloxyethyl)cyanurate ( L) yields 1D loop-and-chain strands. However, the formation of a super-array of strands depends on the nature of the polyatomic anions: BF4- and ClO4- anions induce 1D polyrotaxaned loop-and-chain strands, whereas NO3- anion leads to the formation of 2D-like interdigitated loop-and-chain strands in the crystalline state. Calcination of [Ag3( L)2]3X (X- = BF4- and NO3-) crystals at 500 °C produces silver(0) particles, whereas the same treatment of [Ag3( L)2]3ClO4 crystals affords a mixture of silver(0) and silver(I) chloride. The rates of formation of Ag0 nanoparticles by reduction of crystalline products using ascorbic acid are in the order X- = ClO4- > BF4- > NO3-, and their crystalline morphologies are dependent on the nature of the polyatomic anions.
