This chapter illustrates the relationships between structural and optical properties in oligothiophenes. In particular, it highlights the proper functionalization of the thienyl units with oxygen atoms; it is possible to increase the photoluminescence efficiency up to values comparable and even better than those of the best organic materials commonly used as active compounds in light emitting devices. Such a characteristic, together with the high chemical stability and the wide color tunability, makes oligothiophene-5,5'-dioxides excellent candidates not only for applications to electronic devices, but also to optoelectronic devices, such as multi-color LEDs and lasers. Recent achievement of high-performances thiophene-based devices is discussed.

Abstract

This chapter illustrates the relationships between structural and optical properties in oligothiophenes. In particular, it highlights the proper functionalization of the thienyl units with oxygen atoms; it is possible to increase the photoluminescence efficiency up to values comparable and even better than those of the best organic materials commonly used as active compounds in light emitting devices. Such a characteristic, together with the high chemical stability and the wide color tunability, makes oligothiophene-5,5'-dioxides excellent candidates not only for applications to electronic devices, but also to optoelectronic devices, such as multi-color LEDs and lasers. Recent achievement of high-performances thiophene-based devices is discussed.
