Abstract

Conjugated polymers have unique electronic and optical properties and potential applications in electro-optics and LEDs. The study of the exciton dynamics in conjugated polymers is essential to their applications [1]. This paper reports the study of the exciton dynamics in an optically active poly(arylene vinylene) (PVA) in solutions using femtosecond laser spectroscopy. This polymer has main chain chirality and is the first of its kind. It has potential applications in areas such as asymmetric synthesis [2]. Its strong and relatively blue absorption and emission spectra (Fig. 1) make it attractive for blue LEDs and diode lasers. The molecular structure is shown in Fig. 1.
