This Thesis discussed molecules suitable for photorefractive effect. Out
of the molecules studied, only one system was used to make photorefractive polymers system. Other molecules, especially, the electro-optic
polymer, Poly(3-methacrloyl-1-(4'-nitro-4-azo-1'-phenyl)phenylalanine-co-
methyl methacrylate) can be subjected to more detailed studies to explore
the possibilities of using them for electro-optic applications. Though not included in the thesis, the efficient photoconductor, Poly(6-tert-butyl-3-
phenyl-3,4-dihydro-2H-1,3-benzoxazine) sensitized with C60, which was described in Chapter 3 showed a low magnitude photovoltaic effect. This
hints at the possibility of using this system for organic solar cells also. The thesis presented the initial observation of photorefractive effect in
a polybenzoxazine based polymer system. A detailed analysis of the effect of C60, ECZ and DR1 can be carried out to check for the possibility of a high efficiency photorefractive system. |
