The photochromic materials have been widely applied in many fields. In this article, we report a class of photochromic ammoniums with a dithienylethene backbone. They were utilized as templates to construct mechanically interlocked rotaxanes and pseudorotaxanes showing photo-responsive behavior by template-directed clipping reaction and the threading approach. The structures of novel rotaxanes were well defined. It is worth mentioning that the single crystal structure of [3]rotaxane containing two N-hetero crown ether units was obtained. Their photoisomerization behavior was investigated. These N-hetero crown ether-based rotaxanes displayed good reversibility and similar photochromic behaviors to their corresponding ammoniums when they underwent UV/vis photoirradiation. Interestingly, the cucurbit[6]uril-based pseudorotaxane showed better photoisomerization than its corresponding ammonium and those of N-hetero crown ether-based rotaxanes.

Five modular photoinduced electron-transfer (PET) sensors bearing two phenylboronic acid receptors with different fluorophores have been prepared. The sensors' interaction with saccharides was assessed via fluorescence spectroscopy. It was shown that monosaccharide selectivity is influenced by the choice of fluorescent moiety.

The invention provides compounds for detecting sacchharides by electrochemistry. The compounds have a structure that includes a first boronic acid group attached by a first linker group to a first tertiary amine. The first tertiary amine is attached to a reporter group that includes an organometalic reporter moiety. A spacer group attaches the first tertiary amine to a second tertiary amine. The second tertiary amine is attached to an R group and a second linker group. The second linker group is attached to a second boronic acid group. In preferred embodiments, the compound selectively detects glucose and has a higher relative stability constant for glucose than for other saccharides.

Modular photoinduced electron transfer (PET) sensors bearing two phenylboronic acid groups, a pyrene group and alkylene linkers, from trimethylene to octamethylene, have been prepared and evaluated. The diboronic acid systems with tetramethylene 34 pentamethylene 35 and hexamethylene 36 linkers display the greatest enhancement in binding relative to monoboronic acid 4 with D-glucose. The diboronic acid system with the hexamethylene 36 linker is particularly D-glucose selective and sensitive. Whilst the diboronic acid systems with the longer heptamethylene 37 and octamethylene 38 linkers display the greatest enhancement in binding relative to monoboronic acid 4 with D-galactose. All saccharide titrations were performed in methanolic aqueous solution.

Disclosed is a modular fluorescence sensor having the following general formula: 1Where Fl is a fluorophore, N is a nitrogen atom, Bd1 and Bd2 are independently selected binding groups, Sp is an aliphatic spacer, and An is an anchor group for attaching the sensor to solid substrates. n=1 or 2, m=1 or 2, x is an integer, and y=1 or 2. The binding groups are capable of binding an analyte molecule to form a stable 1:1 complex. In a preferred embodiment, the Bd1 is R1—B(OH)2 and Bd2 is R2—B(OH)2. R1 and R2 are aliphatic or aromatic functional groups selected independently from each other and B is a boron atom. The present invention also provides methods of synthesizing a modular fluorescence sensor and its use in labeling solid substrates.
