Optoelectronic polymers are widely application in polymer light-emitting diodes (PLEDs)

polymer solar cell

polymer laser

polymer field-effect transistor due to their excellent optoelectronic property

easily structural modification and their flexibility and convenient

also defined as fourth-generation polymer. Similar to the traditional polymer

the properties and applications of optoelectronic polymers are dominated by their hierarchical structure

such as short range structure (molecular structure)

long-range structure (molecular behavior and conformational transition)

third level structure (condensed structure) and high level structure (multi-condensed structure to induce novel properties and behaviors for outstanding applications). This review also summarizes recent progresses in studies of the hierarchical structure in optoelectronic polymer

and proposes that it is a key strategy to improve performance

stability of plastic optoelectronic devices
