<P>Hydrogelation of a pyridine derivative (1) possessing tetrazole moieties as end groups, without long alkyl chain groups, results in the formation of a Mg(NO<SUB>3</SUB>)<SUB>2</SUB> coordination polymer gel. The polymer exhibits a strong fluorescence enhancement upon gel formation. 1 can also be gelated with a variety of magnesium anions such as SO<SUB>4</SUB><SUP>2−</SUP>, NO<SUB>3</SUB><SUP>−</SUP>, Cl<SUP>−</SUP>, Br<SUP>−</SUP> and I<SUP>−</SUP>, indicating that the coordination polymer gel formation of 1 does not strongly depend on anions. The SEM and AFM images of Mg<SUP>2+</SUP> coordination polymer gel 1 display a fibrillar network several micrometres long, with widths in the range of 60–70 nm and thicknesses of about 3 nm. In addition, photophysical studies show that the hydrogel exhibits a typical π–π* transition and gives rise to high fluorescence behavior. The coordination polymer hydrogel exhibits viscoelastic behavior as evidenced from the rheological studies.</P> <P>Graphic Abstract</P><P>Hydrogelation of a pyridine derivative (1) possessing tetrazole moieties results in the formation of a Mg<SUP>2+</SUP> coordination polymer.
