“…[409][410][411]414 Moreover, many fulgides and fulgimides show fluorescence, 408,420 which can vary between the two photoisomers. 416,421,422 Fulgides and fulgimides are used in a wide range of applications, for instance, as switchable polymer films, 413,420 on surfaces, 423 and in biological applications. 370,411 Fulgides and fulgimides are less lipophilic than the structurally related DAEs and exhibit the rather polar succinyl moiety.…”

“…6,20 In previous studies, we described the synthesis and investigation of a series of photochromic heterocyclic maleimides, including those capable of detecting cations and anions. 16,21,22 Herein, we report the synthesis of maleimides containing phenanthroline a receptor group in the bridged pyrrole-2,5-dione moiety and investigation of their photochromic, fluorescent and chemosensor properties. The choice of the phenanthroline as the ligand fragment is due to its significant chemosensor activity towards cations.…”

Photochromic indolyl(thienyl)maleimides containing phenanthroline receptor in the bridge moiety were synthesized. Ring-opened maleimides possess fluorescence with quantum yields of 0.027-0.037. Irradiation of their solutions with light of 436 nm results in the formation of non-fluorescent ring-closed isomers. Reopening of the cycle occurs by exposure to visible light (λ > 500 nm). The obtained compounds demonstrate selective chemosensor activity to Fe 2+ ions.
