A sensing element for sensing the concentration of an analyte in a medium is disclosed. The sensing element comprises a matrix material having at least one indicator component covalently bonded thereto. The indicator component is capable of providing a signal dependent on the concentration of a analyte in a medium. The indicator component is derived from at least one indicator compound having an aromatic ring to which is directly bonded a group including a functional portion which is conjugated relative to this aromatic ring.

Sensing elements and methods for making and using same

Nonlinear-optic (NLO) compositions containing functionalized merocyanine dyes, such that the molecules, comprising the NLO-active compositions have a functional group at each end of the molecule and each functional group differing in reactivity, thus permitting stepwise reaction of each functional group, and NLO-active molecules prepared from hemioxonol dyes derviatived with (meth)acrylate or (meth)acrylamide groups, and their uses in devices such as second harmonic generators or polymer integrated optics.
