文摘

A novel interconversion system between less-fluorescent stacked (S) dimer and fluorescent extended (E) dimer ofthe monoimidazolylbisporphyrinatozinc complex was investigated. The addition of pyridine induces transformationfrom the S to the E dimer, whereas the addition of acetic acid and subsequent heating reverses the transformation.The interconversion rate is controlled by ligand concentration and thermal treatment. The system can be appliedto repeatedly readable molecular memory by highly sensitive fluorescence detection.
