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.
