The invention provides a metallopolymer coordination network comprising one or more coinage or similar metals and a glyme or glyme-equivalent. The composition has an amorphous polymer network that is significantly stronger than previously reported supramolecular hydrogels synthesized without glyme. Glyme chain length and water content strongly influence the mechanical, electronic, and optical behavior of the network.

A titanium oxide aerogel particle has absorption at wavelengths of 450 nm and 750 nm in a visible absorption spectrum, a surface to which a metal compound containing a metal atom and a hydrocarbon group is bonded via an oxygen atom, a BET specific surface area in a range of 120 m.sup.2/g to 1,000 m.sup.2/g, and a value A is in the range of 0.03 to 0.3. The value A is calculated by formula: A={(peak intensity of CO bond+peak intensity of CO bond)/(peak intensity of CC bond+peak intensity of CC bond)}. In the formula, the peak intensity is a value determined from a C 1s XPS spectrum.
