Prof. Ho-Chol Chang’s team released the paper on the construction of molecular precursors (MPs) in Inorganic Chemistry and accepted as supplementary cover.

The construction of aluminosilicates from versatile molecular precursors (MPs) is effective method but the use of MPs often suffers from drawbacks such as the decomposition of the core structures in the presence of solvents, acids, or bases.
In this study, Prof. Chang’s team demonstrate a simple thermal synthesis of porous aluminosilicates from single-source spiro-7-type MPs that consist of a tetrahedral Al atom and six Si atoms functionalized with 12 phenyl (Ph) groups,
(C⁺)[Al{Ph₂Si(OSiPh₂O)₂}₂]⁻ (C⁺[AlSi₆]⁻; C⁺ = pyridinium cation (PyH⁺), Na⁺, K⁺, Rb⁺, or Cs⁺), without using a solvent or activator. Microporous aluminosilicates synthesized via the thermal treatment of C⁺[AlSi₆]⁻ under a 79% N₂ + 21% O₂ atmosphere exhibited extremely low carbon contents (0.10–1.28%), together with Si/Al ratios of 3.9–6.7 ± 0.2 and surface areas of 103.1–246.3 m²/g.
The results of the research suggest that the present MP strategy is a promising method for the introduction of key structures into active inorganic materials.
