Photochromic spiropyrans modified with fluorophores were investigated as molecular platforms for the achievement of fluorescence switching through modulation of energy transfer. The dyads were designed in such a way that energy transfer is only observed for the open forms of the photochrome (merocyanine and protonated merocyanine), whereas the closed spiropyran is inactive as an energy acceptor. This was made possible through a deliberate choice of fluorophores (4-amino-1,8-naphthalimide, dansyl, and perylene) that produce zero spectral overlap with the spiro form and considerable overlap for the merocyanine forms. From the Foerster theory, energy transfer is predicted to be highly efficient and in some cases of 100 % efficiency. The combined switching by photonic (light of I>530 nm) and chemical (base) inputs enabled the creation of a sequential logic device, which is the basic element of a keypad lock. Furthermore, in combination with an anthracene-based acidochromic fluorescence switch, a reversible logic device was designed. This enables the unambiguous coding of different input combinations through multicolour fluorescence signalling. All devices can be conveniently reset to their initial states and repeatedly cycled.

Paragraph 0020, (2017/05/12)
The invention discloses a mitochondria fluorescent probe as well as a preparation method and application thereof, belonging to the field of functional materials. The mitochondria fluorescent probe has a double fluorescence emission function and is a quaternary phosphonate compound with a structural formula shown by formula I. In the formula I, R is alkyl or aryl, and the anion X is halogen ion. The fluorescent probe disclosed by the invention has very efficient mitochondria specificity recognition ability, and the fluorescent probe molecule presents a double fluorescence emission phenomenon under the excitation of different lights so as to realize precise double fluorescence labeling of mitochondria. In the invention, the fluorescent probe molecule also has excellent light stability, experiences relatively little influence of the charge change on the mitochondria surface, and can realize real-time tracking of the mitochondria distribution and form in a living cell. Moreover, the mitochondria fluorescent probe disclosed by the invention has the advantages of high water solubility, simple synthesis path, simple after-treatment, batch production, relatively low cost and the like and shows a broad market prospect.
