A capillary gas chromatographic method with an electron capture dector (ECD) for the detection of polychlorinated biphenyls (PCBs) in seawater was developed.

Organohalogen compounds, or OHCs, include dioxins, polychlorinated biphenyls and some pesticides.

In this thesis, a type of biphenyl rod-like liquid crystals and two types of triphenylene discotic liquid crystals were synthesized.
