EXAMPLE 2 Preparation of 2-(4-(1,8-naphthyridin-2-yloxy)phenoxy)propanoic acid STR9 A 3-necked flask was equipped with a thermometer, a magnetic stirrer, a reflux condenser and a nitrogen line and flushed with nitrogen. The flask was charged with 15 ml of hexane and 1.38 gm (28.8 m moles) of 50% NaH/oil dispersion. After stirring for 10 minutes the hexane was decanted and replaced with 5 ml of DMSO followed by the dropwise addition of a solution of 2.18 gm (12 m moles) of 2-(4-hydroxyphenoxy)propanoic acid in 5 ml of DMSO. The mixture was warmed to 60 C. and a solution of 1.97 gm of 2-chloro-1,8-naphthyridine in 10 ml of DMSO was added. After warming the reaction mixture at 95 C. for one hour, the mixture was cooled to room temperature and water cautiously added. The solution was extracted with methylene chloride and the aqueous phase neutralized with acetic acid to give a white precipitate. The aqueous mixture was extracted with CH2 Cl2 and the organic layer washed twice with water, dried over Na2 SO4 and evaporated to dryness to give 3.3 gm of yellow solid which could not be redissolved in ether or CH2 Cl2.

Two extended nickel string complexes, [Ni7(bnapy) 4Cl2](Cl)2 (2) and [Ni9(bnapya) 4Cl2](PF6)2 (3) (bnapy2- = 2,6-bis(1,8-naphthyridylamido)pyridine and bnapya3- = bis(6-(1,8-naphthyridylamido)pyridyl)amido), which possess two redox-active [Ni2(napy)4]3+ units, were synthesized and characterized. The electronic communication between the two redox-active units in both complexes can be investigated not only by magnetic measurements but also by analyzing the difference between two consecutive one-electron oxidation peaks (DeltaE1/2) of 2 and 3. The antiferromagnetic coupling between the two [Ni2(napy)4]3+ fragments become weaker as the metal frameworks are elongated (J = -13.21 and -1.48 cm -1 for 2 and 3, respectively). Moreover, the DeltaE1/2 values of 2 and 3 are 110 and 84 mV, respectively, which are smaller than that (300 mV) of their pentanickel analogue [Ni5(bna)4(Cl) 2](PF6)2 (bna- = bisnaphthyridylamido) (1). These DeltaE1/2 values indicate that the electronic communication decreases with increasing number of inner diamagnetic nickel ions in nickel string complexes.

A conjugated donor-acceptor-donor molecule incorporating a central moiety of naphthyridine and two terminal moieties of di(hydroxyethyl)aniline connected by ethynyl bridges shows two-stage color changes on binding with mercury(II) ion in Me2SO/H2O (1:1) solution with a bathochromic shift from 450 to 498 nm, and then an extraordinarily large hypsochromic shift to 378 nm. In comparison, the corresponding donor-acceptor molecule weakly binds mercury(II) ion with a hypsochromic shift from 408 to 375 nm. Our designed sensor of the donor-acceptor-donor system shows high selectivity toward mercury(II) ion over other competing metal ions.
