Area of Science:

• Materials Science
• Organic Chemistry
• Solid-State Physics

Background:

• Organic electroluminescent (EL) devices require efficient electron-transporting materials.
• 1,3,4-oxadiazole derivatives are promising candidates for such applications.
• Understanding the crystal structure is crucial for material property prediction.

Purpose of the Study:

• To synthesize and characterize a novel 1,3,4-oxadiazole derivative.
• To investigate its potential as an electron-transporting material in organic EL devices.
• To elucidate the crystal structure and intermolecular interactions.

Main Methods:

• Synthesis of the novel 1,3,4-oxadiazole derivative.
• Single-crystal X-ray diffraction analysis.
• Analysis of molecular planarity, hydrogen bonding, and crystal packing.

Main Results:

• The compound, C(24)H(20)N(6)O(2), is a novel 1,3,4-oxadiazole derivative.
• The molecular framework is nearly planar, with intramolecular C-H⋯O and C-H⋯N hydrogen bonds.
• Molecules aggregate via C-H⋯N interactions to form tapes and sheets in the crystal structure.
• The tert-butyl group exhibits disorder over two sites.

Conclusions:

• The novel 1,3,4-oxadiazole derivative shows potential for use in organic electroluminescent devices.
• The observed crystal packing and hydrogen bonding influence the material's properties.
• Further studies are warranted to confirm its electron-transporting capabilities.
