An interfacial electric field intensity of a surface is measured by covalently binding a monolayer of a voltage sensitive chromophore to the surface and irradiating it with actinic radiation while it is in contact with a liquid and measuring a first fluorescence emission spectrum. A solution of the voltage sensitive chromophore dissolved in a sample of the liquid is also irradiated with actinic radiation and a second fluorescence emission spectrum is measured. The first and second fluorescence emission spectra are compared to determine the interfacial electric field intensity.

Method for measuring solid-liquid interfacial electric field

A characteristic difference between first and second liquids is measured using a surface having a monolayer of a voltage sensitive chromophore that is covalently bound to the surface. The first liquid is brought into contact with the surface and it is irradiated with actinic radiation to measure a first fluorescence emission spectrum. The second liquid is also brought into contact with the surface and it is irradiated with actinic radiation to measure a second fluorescence emission spectrum. The first and second fluorescence emission spectra are compared to characterize a difference between the first and second fluids.

Method for determining a characteristics difference between fluids

A characteristic of a liquid is measured by providing a surface having a monolayer of a voltage sensitive chromophore that is covalently bound to the surface. The liquid is brought into contact with the surface and it is irradiated with actinic radiation to measure a first fluorescence emission spectrum. A solution of the voltage sensitive chromophore dissolved in a sample of the liquid is also irradiated with actinic radiation and a second fluorescence emission spectrum is measured. The first and second fluorescence emission spectra are compared to determine the characteristic of the liquid.

Method for characterizing a liquid

A conductive metal pattern is formed in a polymeric layer that has a reactive polymer that comprises (1) pendant groups that are capable of providing pendant sulfonic acid groups upon exposure to radiation, and (2) pendant groups that are capable of reacting in the presence of the sulfonic acid groups to provide crosslinking. The polymeric layer is patternwise exposed to provide a polymeric layer comprising non-exposed regions and exposed regions comprising a polymer comprising pendant sulfonic acid groups. The exposed regions are contacted with electroless seed metal ions to form a pattern of electroless seed metal ions. The electroless seed metal ions are reduced to provide a pattern of electroless seed metal nuclei that are then electrolessly plated with a conductive metal.

Forming conductive metal pattern using reactive polymers

Various patterning methods utilize certain crosslinkable reactive polymers comprise -A- and -B- recurring units, arranged randomly along a backbone. The -A- recurring units comprise pendant aromatic sulfonic acid oxime ester groups that are capable of providing pendant aromatic sulfonic acid groups upon irradiation with radiation having a &#x3bb;of at least 150 nm and up to and including 450 nm. The -A- recurring units are present in the reactive polymer in an amount of up to and including 98 mol % based on total reactive polymer recurring units. The -B- recurring units comprise pendant groups that provide crosslinking upon generation of the aromatic sulfonic acid groups in the -A- recurring units. The -B- recurring units are present in an amount of at least 2 mol %, based on total reactive polymer recurring units.
