In the search for new materials for plastic electronics, π-conjugated oligomers and polymers have received much recent interest. These materials are used in applications such as transistors , photovoltaic cells , molecular wires , electrochromic devices , and fluorescence sensors or imaging]. Chiral π-conjugated polymers show optical absorption and chiroptical activity in OPEN ACCESS Materials 2012, 5 318 visible range . Although natural materials such as cellulose and proteins show intense chiroptical activity in UV region (short wavelengths), they show no absorptions at the visible range. On the other hand, π-conjugated polymers have chromophore and show optical functionality in the visible region. The function of optical rotation in visible-near-infrared region can be useful as an optical isolator for optical fibers. Furthermore,
