Conjugated polymers have recently been shown to exhibit a wide variety of photo-induced and electric field -induced phenomena such as photoconductivity and electroluminescence. We present in this report the recent efforts in our laboratory related to the opto-electronic properties of certain conjugated polymers. The importance of electronic correlations leading to excitonic effects is observed in the photocurrent spectral responses of these polymers. We speculate on the mechanisms of absorption, photocurrent and luminescence on the basis of excitonic response in these polymers. A novel scheme to achieve a high degree of control in the mechanical and electronic properties of these polymers coupled with high photocurrent efficiency is also mentioned.
