Polyfpara-phenylene

The equivalent names from chemistry and physics for the excitations of conducting polymers are summarized in Table VA-1. We use as model systems frans-polyacetylene for the degenerate ground state polymer and polyfpara-phenylene) for the non-degenerate ground state polymer. 

These fibre-formimg polymers are so-called ladder polymers and possess wholly aromatic polymer chains. The two common examples available commercially are the polybenzimidazole FBI (Intertek, formerly Celanese) with the full chemical name poly (2,2 -(m-phenylene)-5,5 -bibenzimidazole) and the polybenzoxazole Zylon (Toyobo) with the full chemical name polyfpara-phenylene benzobisoxazole) and generic acronym PBO. Their similarity in polymer chain stractures and high degrees of...

In the devices described here, we utilized the simplest sandwich structure for the device configuration with p>oly(3,4-ethylenedioxythiophene)-poly(styrene sulfonate) (PEDOT-PSS) coated indium-tin-oxide (ITO) glass as the anode and aluminum as the cathode. The well-known soluble phenyl-substituted polyfpara-phenylene vinylene) (PPV) copolymer ("superyellow" from Merck/Covion) (Spreitzer et al., 1998) was selected as our host light-emitting polymer and an organic ionic liquid, methyltrioctylammonium trifluoromethanesulfonate (MATS), was used to introduce a dilute concentration of mobile ions into the emitting polymer layer.
