Abstract: The aim of this work is to serve as a guideline for the initial selection of monomer and solvent for the synthesis of the nitrocompound-based molecularly imprinted polymers, MIPs. Reported data include evaluation of six systems with the ability to form noncovalently bonded monomer-template complexes. These systems are represented by the following aliphatic and aromatic molecules: acrolein, acrylonitrile, 2,6-bisacrylamide, 4-ethylenebenzoic acid, methyl methacrylate, and 2-vinylpyridine. Cave models for selected monomers are also presented and supported by binding energy analysis under various conditions. Solvent effects on monomer-template binding energy have been studied for four solvents: acetone, acetonitrile, chloroform, and methanol. Additionally, systems such as 2,4-dinitrotoluene (2,4-DNT), 2,6-dinitrotoluene (2,6-DNT), pentachlorophenol (PCP), and 3,6-dichloro-2-methoxybenzoic acid (Dicamba) have been used to study selectivity of acrolein-based MIP toward TNT detection. The density functional theory, DFT, method has been used for all structural, vibrational frequency, and solvent calculations
