Abstract
Self-assembly of Zn(ClO4)2 with 1,3,5-tris(dimethyl(pyridin-3-yl)silyl)benzene (L) as a new C3-symmetric tridentate N-donor gives rise to a discrete sandwich-shaped M3L2 architecture, [Zn3(μ-OH)3L2](ClO4)3·4CH3CN·2H2O. Its blue photoluminescence is significantly quenched only by CH2I2 among the various small molecules, CH2Cl2, CH2Br2, CHCl3, 1,2-dichloroethane, EtOH, CH3CN, benzene, toluene, and phenol.
