Recent advances in conjugated polymers for light emitting devices.

Alsalhi MS, Alam J, Dass LA, Raja M - Int J Mol Sci (2011)

Bottom Line: Recently, developed conjugated polymers are also functioning as roll-up displays for computers and mobile phones, flexible solar panels for power portable equipment as well as organic light emitting diodes in displays, in which television screens, luminous traffic, information signs, and light-emitting wallpaper in homes are also expected to broaden the use of conjugated polymers as light emitting polymers.Furthermore, since conjugated polymers have been approved as light-emitting organic materials similar to inorganic semiconductors, it is clear to motivate these organic light-emitting devices (OLEDs) and organic lasers for modern lighting in terms of energy saving ability.In addition, future aspects of conjugated polymers in LEDs were also highlighted in this review.

ABSTRACT
A recent advance in the field of light emitting polymers has been the discovery of electroluminescent conjugated polymers, that is, kind of fluorescent polymers that emit light when excited by the flow of an electric current. These new generation fluorescent materials may now challenge the domination by inorganic semiconductor materials of the commercial market in light-emitting devices such as light-emitting diodes (LED) and polymer laser devices. This review provides information on unique properties of conjugated polymers and how they have been optimized to generate these properties. The review is organized in three sections focusing on the major advances in light emitting materials, recent literature survey and understanding the desirable properties as well as modern solid state lighting and displays. Recently, developed conjugated polymers are also functioning as roll-up displays for computers and mobile phones, flexible solar panels for power portable equipment as well as organic light emitting diodes in displays, in which television screens, luminous traffic, information signs, and light-emitting wallpaper in homes are also expected to broaden the use of conjugated polymers as light emitting polymers. The purpose of this review paper is to examine conjugated polymers in light emitting diodes (LEDs) in addition to organic solid state laser. Furthermore, since conjugated polymers have been approved as light-emitting organic materials similar to inorganic semiconductors, it is clear to motivate these organic light-emitting devices (OLEDs) and organic lasers for modern lighting in terms of energy saving ability. In addition, future aspects of conjugated polymers in LEDs were also highlighted in this review.

Mentions: The recent and rapid development of materials and devices designed for efficient manufacture have endowed the concept of “polymer light” with the optical, electrical, and mechanical characteristics that truly make it a disruptive technology within the display and lighting industries, in that it is compatible with conventional device replacement and offers new opportunities for exploitation [22–27]. Concerning “polymer light”, the discovery in Cambridge of electroluminescence (EL), which is the emission of light when excited by flow of an electric current, in conjugated polymers has provided a new impetus to the development of light-emitting devices (LEDs) for display and has a promising future for other purpose [28]. The major scientific interests in conjugated polymers for material scope and development are shown in Figure 1:
