| Abstract |
The photoelectric effect is that light is converted into an electric current, similar to eyes, and the most popular photoelectric devices are CMOS image sensors and digital X-ray sensors. For their flexible application, we have developed several conjugated polymers containing weak electron accepting moieties to absorb the green-yellow light effectively. We modified the π conjugation length of the polymer backbone to promote the molecular stacking and the charge transfer process. In addition, the different molecular orientation of polymer chains gave a significant effect on photo-sensitivity and photo-detectivity, resulting in the promising detectivity of over 1013 Jones up to -2V. UV-vis spectra, space-charge limited current (SCLC) mobility, two dimensional grazing incidence X-ray diffraction (2D-GIXD) patterns, and transmission electron microscopy (TEM) were investigated, in detail, to support the our expectations and photoelectric properties. |
