Polymer optoelectronic organics

The above requirements can be summarized in the following general design goals for polymeric optoelectronic materials  

Control of FIOMO and LUMO energies relative to the vacuum level. 

Control of crystallinity and molecular organization for improved carrier transport characteristics. 

Achieving a large range of ratios of carbocation and carbanion mobilities to provide effective electron and hole transporting materials capable of resisting transport of the other species. 

Control the luminescent wavelength and maximized radiative relative to non-radiative recombination of excitons.

We close this chapter with further statements on liquid crystals as a preferred material for optical and electro-optical applications. To date, liquid crystals and related optical technologies have been incorporated in the design and fabrication of filters, lens, waveguides, diffractive and reflective elements, routers and interconnects, etc., of various forms, shapes, and functions used in optical communication system" as well as in free-space beam steering systems. Their compatibility with almost all optoelectronic materials as well as polymers and organic materials allows even more possibilities and flexibility in the emerging field of flexible displays" and polymer cholesteric liquid crystal flake/fluid display. 

The diverse properties of organic molecular materials, of which the polymers are amongst the primary ones, will, without doubt, be intensively developed in the future. Photosensitive polymer semiconductors with pre-given properties and a broad spectrum of application will be created for various optoelectronic devices.
