The typical structural characteristic of the title compound is the methanol group adopting a mu(2)-bridging mode to link two different adjacent chelating modes though two types of hydrogen bonds to form a one-dimensional supramolecular structure. Additionally, aromatic pi-pi stacking interactions between adjacent benzimidazolyl groups lead to a three-dimensional network. Furthermore, the stability and fluorescence property revealed the potential applications in the organic photoelectric material.

The efficiency of the prepared nanostructure has been explored for the synthesis of benzimidazoles via the condensation reaction of orthoesters and diamines at 60 degrees C under solvent-free conditions. The successful synthesis of benzoxazole has also been explored through the condensation of orthoesters with 2-aminophenol in water media at room temperature. The recovery and reusability of the nanocatalyst has also been examined via 4 runs without activity loss. Partial short reaction times, high yields of products, mild reaction conditions in the absence of any hazardous solvent, and reusability of the nanocatalyst are noteworthy advantages of this method.

Now introduce a scientific discovery about this category.

A new ring opening reaction was found while attempting to isolate the imines from ortho-heteroatom substituted anilines and camphor-like bicyclic ketones. The benzoazoles containing a cyclopentanemethyl group at position 2 of the heterocycle were isolated instead of the expected imines. The detailed study of the transformation, including EPR experiments, revealed the most probable radical mechanism. The proposed reaction pathways were confirmed by quantum chemical calculations. The dichotomy of 1-2 and 2-3 bonds cleavage is discussed together with the evaluation of the stereochemical outcome of the reactions. The benzoazoles obtained via the new reaction are of particular interest for the medicinal chemistry.
