p- and n-doped states of thiophene-benzothiadiazole based donor–acceptor π-conjugated polymer materials are studied. Results reveal that mesomeric factors mainly influence p-doping, while steric factors account for n-doping peculiarities.

Important Significance

AbstractThe evaluating mechanical performance of Π-conjugated Polymer films has important significance for application in the micro electronic devices. In this work, authors studied micro mechanical performance of Π-conjugated polymer, poly[2-methoxy-5-(2’-ethyl hexyloxy)-phenylene vinylene] used nanoindentation technique at room temperature and discussed effect of experimental parameter on the effective elastic modulus and hardness of MEH-PPV film. The experimental result indicates the estimating effective elastic modulus and hardness using O & P formula are correlative with load, holding time, and loading rate. Detail analysis in combination with related literature indicated the effective elastic modulus and hardness of MEH-PPV film are approximately 6.79±0.12GP, 0.37±0.16 GP, respectively. Furthermore, increasing the loading rate could decrease the effective elastic modulus and hardness, which was opposite comparing with typical polymer materials (poly (methyl methacrylate) (PMMA) etc ).

Novel Method

ABSTRACTIn this paper we present a combined protocol for ultrathin film formation and assembly of Φ- conjugated polymer materials using the layer-by-layer (LbL) technique and a precursor polymer approach to electrodeposition. While much work has been done on investigating the chemistry (synthesis) and properties (physics) of these materials, little focus has been given on the multilayer and ordering issues associated with ultrathin film formation especially using novel “wet-processing” approaches. This work details our molecular assembly approaches on conjugated polymer systems for polyfluorene and polythiophene derivatives. This was demonstrated in the following systems: a) ionene precursor polyfluorene polymers deposited as ultrathin films using the LbL technique from an aqueous solution and b) electrodeposition of polysiloxane modified precursor polymers. Important strategies are outlined for combining the two techniques as a novel method for preparing ultrathin films and patterning.
