Dipolimomentien

Dipolimomentien is a hypothetical organic compound used in theoretical chemistry and materials science to explore the relationship between molecular structure and dipole moment in conjugated systems. The name combines the concept of dipole moment with the suffix -ien, following conventions for naming fictional molecules in chemical modelling.

Chemical structure and properties: Dipolimomentien is described as a highly conjugated, linear polyene with a central core flanked by polarizable substituents, producing a substantial ground-state dipole moment. In models, its approximate formula is C22H18, with planarity that favors pi-electron delocalization. The compound is assumed to be colorless and moderately stable under inert conditions, with properties sensitive to substituent effects and solvent polarity.

Synthesis and modelling: In theoretical literature, dipolimomentien is generated in silico by stepwise assembly of two para-substituted phenyl vinyl units through pericyclic coupling, followed by controlled dehydrogenation to maximize conjugation. No experimental synthesis has been reported, as the compound remains a modelling construct. It serves as a benchmark for computational methods predicting polarity and optical properties.

Applications: It is used to study how molecular geometry influences dipole moment, dielectric constants, and nonlinear optical responses in simulations. Some models employ dipolimomentien to examine solvent effects on polar conjugated molecules and to test methods for predicting electronic structure.

Safety: No real-world hazards are established because the compound has not been synthesized. If encountered in speculative work, standard laboratory safety applies as for organic polar hydrocarbons, including use of a fume hood and appropriate PPE.
