Abstract
Compositions are provided comprising: 1) a solid metal oxide support having surface hydroxyl groups; 2) a silyl-containing compound bound to the solid metal oxide support through a silanol bond with the surface hydroxyl groups; and 3) a bis(glyoxime)-transition metal complex bound to the solid metal oxide support. These compositions can be used to make a colorimetric relative humidity-indicating sensor. A method of adjusting the colorimetric response of a moisture-indicating composition and a method of detecting moisture are also provided.
