Zero-dimensional (0D) organic metal halide hybrids, in which organic and metal halide ions cocrystallize to form neutral species, are a promising platform for the development of multifunctional crystalline materials. Herein we report the design, synthesis, and characterization of a ternary 0D organic metal halide hybrid, (HMTA)4PbMn0.69Sn0.31Br8, in which the organic cation N-benzylhexamethylenetetrammonium (HMTA+, C13H19N4+) cocrystallizes with PbBr42?, MnBr42?, and SnBr42?. The wide band gap of the organic cation and distinct optical characteristics of the three metal bromide anions enabled the single-crystalline “host–guest” system to exhibit emissions from multiple “guest” metal halide species simultaneously. The combination of these emissions led to near-perfect white emission with a photoluminescence quantum efficiency of around 73 percent. Owing to distinct excitations of the three metal halide species, warm- to cool-white emissions could be generated by controlling the excitation wavelength.

Bis (1-benzyl-3,5,7-triaza-1-azoniatricyclo [3.3.1.13,7] decane) peroxodisulfate was readily prepared as an white solid from commercially available hexamethylenetetramine and potassium peroxodisulfate. This reagent could be used as a stable, mild and efficient oxidizer to produce the corresponding carbonyl compounds from hydroxyl compounds or hydrazones or oximes and disulfides from thiols under anhydrous and aprotic conditions. The yields were almost quantitative, and the reaction time was very short.
