Abstract

A new class of benzospiropyran has been synthesized by the condensation of the precursor, Fisher basespiropyran with substituted salicyaldehydes in 1:1 mole ratios. This photochromic compound, spiro [2H-1-benzopyran-2, 2'-(8'-hydroxy-1', 3', 3'-trimethylindoline)] was able to undergo convertion into its merocyanine form (colored) after being induced by irradiation of UV light. Both open and closed form of benzospiropyran were characterized and distinguished based on Infrared vibracional spectroscopy in Attenuated Total Reflexion mode (ATR) and UV-vis spectroscopy. In addition, association of ten different metal ions to ethanol solution of SP (A) leads to metal-ion bindingby the MC isomer. The coupled reaction of all metal ions, MC-M2+ underwent a hypsochromic and bathochromic shift in the absorption bands.
