英文摘要	We have designed and synthesized a new class of spiropyran derivatives (SP1-SP4) with functional chelating groups, such as pyridine or quinoline moieties and a methoxy group (-OMe), for use in metal ion sensing and information processing at the molecular level. It is notable that metal ions can favor coordination with chelating groups and facilitate the photoisomerization of spiropyran molecules from the closed form to the open merocyanine form without UV irradiation, thus leading to significant changes in their chemical and physical properties. UV-Vis absorption studies indicated that SP2 and SP4 exhibited metal ion-dependent reversible binding affinities that result in different hypsochromic shifts for the MC-Mn+ complexes. These changes in color can be recognized by eye, thus offering an easy colorimetric method for metal ion detection. Further emission studies distinguished them as promising candidates for Zn2+ detection with good sensitivity and selectivity. Moreover, on the basis of their absorption and fluorescence spectra, several combinational logic gates were constructed for information processing at the molecular level. These results demonstrate that spiropyran derivatives with desired functionalities show great potential not only for chemical or environmental sensors, but also for future molecular computing.
