N,N-Dimethyltetradecylamine has emerged as an effective organic template in the synthesis of hierarchical porous metal-organic frameworks (HP-MOFs), particularly Cu-BTC. This tertiary amine plays a crucial role in directing the formation of mesopores and macropores within the MOF structure, enabling tunable porosity essential for adsorption, catalysis, and separation applications.
In a solvothermal approach, N,N-dimethyltetradecylamine was introduced alongside 1,3,5-benzenetricarboxylic acid (H₃BTC) and Cu(NO₃)₂·3H₂O to facilitate the formation of Cu-BTC HP-MOFs. The porosity of the resulting materials was modulated by varying the molar concentration of the amine template. Characterization via X-ray diffraction, nitrogen adsorption-desorption isotherms, and electron microscopy confirmed the presence of interconnected micropores, mesopores, and macropores, enhancing mass transport and accessibility.
Density functional theory (DFT) calculations indicated that the amine group in N,N-dimethyltetradecylamine readily interacts with electrophilic species, influencing pore formation. The template removal process, achieved through solvent extraction at elevated temperatures, ensured the structural integrity of the HP-MOFs.
This work highlights the versatility of N,N-dimethyltetradecylamine as a structure-directing agent in HP-MOF synthesis. The ability to tailor porosity by adjusting template concentration offers a scalable route for developing functional MOFs with potential applications in gas storage, catalysis, and drug delivery.

N,N-Dimethyltetradecylamine is a critical precursor in the synthesis of epoxy-functionalized quaternary ammonium surfactants, which exhibit enhanced surface activity, antibacterial efficacy, and reactivity. One such compound, N-tetradecyl-N,N-dimethyl-N-(2,3-epoxy propyl) ammonium chloride (TDEAC), is synthesized via a nucleophilic substitution reaction involving N,N-dimethyltetradecylamine and epichlorohydrin.
The synthesis is carried out in a desiccative flask, where N,N-dimethyltetradecylamine (0.05 mol) reacts with an excess of epichlorohydrin (0.15 mol) at 20°C for 2 hours under continuous stirring. The crude product undergoes purification through sequential washing with anhydrous diethyl ether and freeze-drying. Structural analysis using ¹H NMR spectroscopy and elemental composition verification confirms the successful formation of TDEAC.

N,N-Dimethyltetradecylamine plays a crucial role in the synthesis of bis-quaternary ammonium salt surfactants, which are widely used for their antibacterial, foaming, and emulsifying properties. In a recent study, 2-hydroxy-N1,N1,N3,N3-tetramethyl-N3-tetradecylpropane-1,3-diammonium chloride (HPTDC) was synthesized using N,N-dimethyltetradecylamine as a primary reactant.
The synthesis involved reacting N,N-dimethyltetradecylamine (0.10 mol) with 3-chloro-2-hydroxypropyltrimethylammonium chloride (M, 0.10 mol) in a solvent mixture of ethanol and water. The reaction was conducted in a three-necked flask under reflux at 80°C for 5 hours, followed by solvent removal and recrystallization using an ethanol-ethyl acetate mixture. The final product, HPTDC, was obtained as a white solid with a high yield of 82.5%.
This bis-quaternary ammonium surfactant exhibited superior surface activity compared to traditional monomeric quaternary ammonium compounds, demonstrating strong antibacterial efficacy against Gram-positive and Gram-negative bacteria. Additionally, HPTDC showed enhanced foaming and emulsification properties, making it suitable for applications in antimicrobial coatings, personal care formulations, and industrial cleaners.
The successful synthesis and characterization of HPTDC highlight the importance of N,N-dimethyltetradecylamine as a versatile precursor in designing next-generation surfactants with optimized performance for diverse industrial and scientific applications.
