Two series of novel spiropyrans and spirooxazines having a heteroaromatic pendant were synthesized using two convenient methods. Their photochromic behaviors were investigated with the aid of absorption spectral measurements. The compounds showed several features different from the parent Spiro compounds, including an inhibitory effect on the fatigue during the photochromic process of spiropyrans.
