Zinc porphyrin is one of most frequently employed photoactive molecules due to its spectral and redox properties. Numerous research groups have designed and prepared the molecular energy storage devices containing porphyrin moiety. Spiropyran is well-known photochromic compound accomplishing molecular structural change to merocyanine form by ring opening on UV irradiation. In turn, merocyanine is transformed to spiropyran by ring closure on irradiation of visible light Reversible photochromic spiropyran-merocyanine transformation is one of the subject of active research on optical memory and switch. Incorporating photochromic molecules into organic materials leads to photoresponsive systems, the properties of which can be manipulated by light. Because absorption spectra of two isomeric molecules are significantly different, the color change is the most spectacular evidence of photochromism. Besides this color change, many molecular and bulk properties also change in the case of incorporating photochromic molecules into organic materials. In this study, Zinc porphyrin-spiropyran dyad was prepared and the photochromic behavior was investigated.
