Compound CAS No. 124481-62-5: 3,7,11,18,22,26-Hexaazatricyclo[26.2.2.2¹³,¹⁶]tetratriaconta-13,15,28,30,31,33-hexaene

The compound with CAS No. 124481-62-5 is a highly complex organic structure known as 3,7,11,18,22,26-Hexaazatricyclo[26.2.2.2131?]tetratriaconta-13,15,2?3?3133-hexaene. This molecule belongs to the class of polycyclic aromatic hydrocarbons (PAHs) with multiple nitrogen atoms incorporated into its structure. The name itself suggests a highly symmetrical and intricate framework with six nitrogen atoms (hexaaza) distributed across the tricyclic system.

The tricyclo[2?.2.22131?] framework indicates a fused ring system composed of three rings with specific bridge positions defined by the numbers in the brackets. The tetratriacontane part of the name signifies a 40-carbon chain (tetracontane) with three double bonds (triene). The positions of these double bonds are at carbons 13 and 15 (on one ring) and carbons 2?3?3133 (on another ring), creating a conjugated system that contributes to the molecule's stability and electronic properties.

Recent studies have focused on the synthesis and characterization of such complex PAHs due to their potential applications in materials science and electronics. The presence of multiple nitrogen atoms in the structure introduces unique electronic properties that make this compound a candidate for advanced materials such as semiconductors or optoelectronic devices.

One of the most significant advancements in this field involves the use of transition metal-catalyzed coupling reactions to synthesize such large polycyclic systems efficiently. Researchers have employed palladium-catalyzed cross-coupling reactions to assemble the tricyclic framework step by step. These methods not only improve yield but also allow for precise control over the placement of functional groups within the molecule.

The hexaene component of this compound plays a crucial role in determining its optical properties. The conjugated double bonds absorb light in specific wavelengths, making this molecule potentially useful in light-emitting diodes (LEDs) or solar cells where wavelength-specific absorption is critical.

Moreover, computational chemistry has played a pivotal role in understanding the electronic structure of this compound. Density functional theory (DFT) calculations have revealed that the hexaaza groups significantly alter the HOMO-LUMO gap compared to analogous non-nitrogenated PAHs. This insight is valuable for designing molecules with tailored electronic properties for specific applications.

In terms of stability and reactivity, this compound exhibits remarkable thermal stability due to its rigid tricyclic framework and extensive conjugation system. Experimental studies have shown that it retains its structural integrity under high temperatures and pressures typical in industrial processes.

Another area of interest is the potential use of this compound as a precursor for carbon-based nanomaterials such as fullerenes or graphene derivatives. The large aromatic system can serve as a template for controlled carbon deposition under high-energy conditions.

Lastly, environmental considerations are increasingly being integrated into synthetic chemistry research involving such compounds. Researchers are exploring green chemistry approaches to minimize waste and energy consumption during synthesis while ensuring scalability for industrial applications.
