[摘要]：Photochemistry, and Photographic and Other Reprographic Pseudorotaxane complexes of squaraine dyes and tetralactam macrocycles are converted into permanently interlocked rotaxane structures (I and II, I and III resp. interlocking) using copper-catalyzed and copper-free cycloaddn. reactions with bulky stopper groups. The photophys. properties of the encapsulated squaraine depend on the structure of the macrocycle. In one case, squaraine rotaxanes are produced in near-quant. yields and with intense near-IR fluorescence. In another case, squaraine fluorescence is greatly diminished upon macrocyclic encapsulation but the signal can be restored by dye displacement with anions.
