Oligo(p-phenylene vinylene) amphiphiles and methods for self-assembly
INVENTION: Amphiphilic oligo(p-phenylene vinylene) compounds and methods of use en route to self-assembled composites and device fabrication.Accordingly, it is an object of the present invention to provide OPV compounds and/or methods for assembly, thereby overcoming various deficiencies and shortcomings of the prior art, including those outlined above. It will be understood by those skilled in the art that one or more aspects of this invention can meet certain objectives, while one or more other aspects can meet certain other objectives. Each objective may not apply equally, in all its respects, to every aspect of this invention. As such, the following objects can be viewed in the alternative with respect to any one aspect of this invention.
It is an object of the present invention to provide an amphiphilic OPV compound without resort to hydrophobic and/or hydrophilic components transverse to the OPV molecular axis, and without introducing an element of steric hindrance for disruption of co-planarity within the conjugated system. It can be another object of the present invention to provide OPV amphiphiles end-substituted, symmetrically or asymmetrically, for self-assembly under a range of fabrication conditions.
Other objects, features, benefits and advantages of the present invention will be apparent from this summary and its descriptions of certain embodiments, and will be readily apparent to those skilled in the art having knowledge of various electro-optic compounds, compositions, components and/or devices. Such objects, features, benefits and advantages will be apparent from the above as taken into conjunction with the accompanying examples, data, figures and all reasonable inferences to be drawn therefrom.
The present invention relates to OPV amphiphiles, either asymmetrically hydrophobic and hydrophilic end-substituted and comprising a triblock configuration, or end-substituted with combined hydrophobic/hydrophilic moieties. Accordingly, in part, this invention comprises compounds of a formula
