Abstract
Abstract Metal is photolytically deposited from solution onto a substrate in contact with the solution by irradiating with light a solution containing a solubilized metal source and an organic compound containing a plurality of proximal Lewis base substituent groups so as to be capable of promoting the photoreduction of the metal onto the substrate.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
81 words
A process for the substantially photolytic deposition of a metal from a substantially anhydrous solution onto a substrate which comprises the irradiation with light of a solution consisting essentially of a solvent, a solubilized metal source and, as photosensitizer an organic compound containing a plurality of proximal Lewis base groups capable of coordination with the metal species so as to be capable of promoting the photoreduction of the metal onto the substrate when the solution is in contact with the substrate.
Claim 2
Dependent Claim
81 words
A process for the substantially photolytic deposition of a metal from a substantially anhydrous solution onto a substrate which comprises the irradiation with light of a solution consisting essentially of a solvent, a solubilized metal source and, as photosensitizer an organic compound containing a plurality of proximal Lewis base groups capable of coordination with the metal species so as to be capable of promoting the photoreduction of the metal onto the substrate when the solution is in contact with the substrate.
Claim 3
Dependent Claim
19 words
A process as claimed in claim 1 wherein the solubilized metal source is a 1,3-dicarbonyl complex of the metal.
Claim 4
Dependent Claim
19 words
A process as claimed in claim 1 wherein the compound capable of promoting the photoreduction is a vicinal diamine.
Claim 5
Dependent Claim
25 words
A process as claimed in claim 1 wherein the solution is substantially anhydrous and the solubilized metal source is a dicarbonyl complex of the metal.
Claim 6
Dependent Claim
21 words
A process as claimed in claim 4 wherein the compound capable of promoting the photoreduction is an aromatic substituted vicinal diamine.
Claim 7
Dependent Claim
18 words
A process as claimed in claim 1 wherein the compound capable of promoting the photoreduction is a pinacol.
Claim 8
Dependent Claim
15 words
A process as claimed in claim 6 wherein the pinacol is an aromatic substituted pinacol.
Claim 9
Dependent Claim
15 words
A process as claimed in claim 3 wherein the vicinal diamine is an aromatic diamine.
Claim 10
Dependent Claim
15 words
A process as claimed in claim 5 wherein the vicinal diamine is an aromatic diamine.
Claim 11
Dependent Claim
16 words
A process as claimed in claim 1 wherein the organic compound is an aromatic vicinal diamine.
