A designed photochromism of spiropyran derivative, 1’ ethyl 3’,3’ dimethyl 6 nitrospiro[4’,5’ benzoindole 2,2’ chromene] (BI SP) as a chemosensor has been synthesized successfully. The as prepared BI SP as colorimetric sensor is sensitive to common trivalent metal ions (M3+3+)), such as Al3+3+, Cr3+ and Fe3+3+. The dye solution is colorless under visible light irradiation and remains so even upon addition of the Al3+3+, Cr3+ and Fe3+ metal ions. However, the dye solution originally appears purple red in the darkness and gradually turned yel low upon addition of the metal ions at room temperature. Moreover, the sensing abilities of the BI SP toward the metal ions (Al3+3+, Cr3+ and Fe3+3+) were also investigated by UV Vis absorption spectra and Infrared ( IR ) spectra. The results indicated that BI S P could be applied as a sensitive and reversible colorimetric sensor for Al3+3+, Cr3+ and Fe3+.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
