Syntheses and Physical Properties of Cationic BN?Embedded Polycyclic Aromatic Hydrocarbons
نویسندگان
چکیده
Cationic BN-embedded polycyclic aromatic hydrocarbons (BN-PAH+s) were synthesized from a nitrogen-containing macrocycle via pyridine-directed tandem C?H borylation. Incorporating BN into PAH+ resulted in remarkable hypsochromic shift due to an increase the LUMO energy and symmetry changes of HOMO LUMO. Electrophilic substitution or anion exchange BN-PAH+ possessing tetrabromoborate as counter (BN+[BBr4?]) afforded air-stable BN-PAH/PAH+s. Of these, BN+[TfO?] allowed reversible two-electron reduction formation two-dimensional brickwork-type ?-electronic ion pair with 1,2,3,4,5-pentacyanocyclopentadienyl anion, demonstrating potential application electronic materials.

Sources, properties and health risks of carcinogenic polycyclic aromatic hydrocarbons
In the present review article focus on highlighting the sources, properties and health risks of carcinogenic PAHs both on human health and environment. Polycyclic Aromatic Hydrocarbons (PAHs) comprises a broad family of compounds that are also described as semi volatile organic compounds (SVOC). This term refers to the fact that PAHs are distributed between gas and particle phases. In fast budd...
متن کاملMutagenic and carcinogenic properties of polycyclic aromatic hydrocarbons.
The rapid development of the chemical industry, combustion of fossil fuels, and smoking of tobacco have resulted in contact of the general population with benzo(a)pyrene and other carcinogenic aromatic hydrocarbons. Persons especially at risk occupationally are those engaged in thermal processing of oil shale, coal, and heavy residual petroleum. It has been shown that polycyclic aromatic hydroc...
متن کاملPhysical origins of interactions in dimers of polycyclic aromatic hydrocarbons.
Dimers of several polycyclic aromatic hydrocarbons (PAHs): naphthalene, anthracene and pyrene have been investigated by symmetry-adapted perturbation theory based on the density functional description of the monomers [SAPT(DFT)]. Calculations have been performed for a number of radial cross-sections of selected stacked and T-shaped configurations. The interaction energies at the minima of stack...
متن کاملBiodegradation of Polycyclic Aromatic Hydrocarbons (PAHs) in Petroleum Contaminated Soils
Polycyclic aromatic hydrocarbons are a class of potentially hazardous chemicals of environmental and health concern. PAHs are one of the most prevalent groups of contaminants found in soil. Biodegradation of complex hydrocarbon usually requires the cooperation of more than single specie. In this research biotreatment of PAH (phenanthrene) was studied in a solid-phase reactor using indigenou...
متن کاملTransport of Polycyclic Aromatic Hydrocarbons in a Calcareous Wetland Soil
Knowledge of transport and degradation of polycyclic aromatic hydrocarbons (PAHs) is important in assessing PAH contamination of soils and water resources. The transport of naphthalene, anthracene, pyrene and phenanthrene was determined in a contaminated calcareous soil obtained from the Shadegan wetland (Khozestan, Iran) considering a column study in laboratory conditions. The PAHs were added ...
