Poly(6‐ tert ‐butyl‐3,4‐dihydro‐ 2H ‐1,3‐benzoxazine) was synthesized by thermally activated cationic ring opening polymerization. The structure of the polymer was confirmed by spectral and thermal studies. The highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO) were estimated using cyclic voltammetry and optical absorption. Modulated photocurrent measurement technique was employed to study the spectral and field dependence of photocurrent. Photocurrent of the order of 1.5 µA/m 2 was obtained for polymer at a biasing electric field of 40 V/µm.
