  A method for the degradation of polycyclic aromatic compounds is disclosed that involves dissolving ozone in a bipolar solvent comprising a non-polar solvent in which is of sufficiently non-polar character to solubilized the polycyclic aromatic compounds, and a polar-water-compatible solvent which is fully miscible with the non-polar solvent to form a single phase with the non-polar solvent. The bipolar solvent with dissolved ozone is contacted with the polycyclic aromatic compounds to solubilize the polycyclic aromatic compounds and react the dissolved polycyclic aromatic compounds with the ozone to degrade the dissolved polycyclic aromatic compounds to oxygenated intermediates. The bipolar solvent is then mixed with sufficient water to form separate non-polar and polar phases, the non-polar phase comprising the non-polar solvent and the polar phase comprising the non-polar solvent and the oxygenated intermediates. The polar phase is then diluted and incubated with bacteria to biodegrade the oxygenated intermediates.

  radical anions were greatly dependent on the structures of isomers. The radical anions of Ia, IIa, and IIb illustrated NIR absorptions peaked at 820, 1260, and 1380 nm, respectively, but that of Ib exhibited only weak absorption in the visible region centered at 660 nm. Gaussian calculations suggested that the electrons were delocalized over the whole molecular skeletons of Ia and IIa radical anions, but

  为了深入研究蒽醌酰亚胺的分子结构与近红外电致变色之间的相互作用，合成了蒽醌酰亚胺的两对未取代异构体（Ia和Ib）和硝基取代异构体（IIa和IIb），其中分子Ia和IIa比Ib和IIb具有更多的线性形状。结合循环伏安法和光谱电化学研究其电化学性质。循环伏安法显示Ib和IIb揭示与它们的异构体相比，首次还原电势降低且循环稳定性低，表明异构化削弱了稳定作用。在单电子还原时，自由基阴离子的吸收波长和吸收强度都极大地取决于异构体的结构。Ia，IIa和IIb的自由基阴离子显示NIR吸收分别在820、1260和1380 nm处达到峰值，但是Ib的阴离子仅在以660 nm为中心的可见区域中显示弱吸收。高斯计算表明，电子在Ia和IIa的整个分子骨架上都离域化了自由基阴离子，但有效结合长度在Ib和IIb的酰亚胺部分中断了。考虑了异构体对有效共轭长度和电子密度分布的影响，以合理化不同的电致变色行为。
