Electroactive Liquid Crystalline Polymers ☆
2017
As with low molecular mass liquid crystals, the polymeric liquid crystalline compounds show many possibilities for interaction with electrical fields. Charge transport via the aromatic cores allows the construction of light emitting devices, field effect transistors and photovoltaic cells. The order of the liquid crystalline phases helps to improve intramolecular charge transfer and the mobility allows easy alignment. Liquid crystalline polymers with ferroelectric phases can be used in fast switching optical devices. Their unique switching mechanism proceeds under reduced interaction with the polymer chains. The combination of liquid crystallinity with elastomer networks leads to electromec…
Liquid crystalline phases from polymer functionalized ferri-magnetic Fe3O4nanorods
2017
Here, we present the surface functionalization of anisotropic in form ferri-magnetic Fe3O4-nanorods (NRs) with a diblock copolymer, having a PMMA- or PDEGMEMA-block, for solubilization, and a dopamine anchor block. These polymers were synthesized through RAFT polymerization via a macro-initiator approach. The successful surface functionalization, performed via a grafting-to method, was monitored using TGA, IR and TEM measurements. The NRs were very soluble in organic solvents after functionalization. Afterwards, the liquid crystalline (LC) behavior was investigated. During solvent evaporation, birefringent domains were formed. The self-assembly into lyotropic LC structures could be observed…
