Platinum complexes of the type [(COD)Pt[O(CO)R1]2]n, where R1 is a non-aromatic C7-C17 hydrocarbon radical, are prepared via ligand exchange in a two-phase system, allowing for the formation of platinum layers on substrates at lower temperatures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional platinum preparation methods using colloidal platinum or nanoplatinum are employed, then platinum layers can be formed, but high temperatures are required and there are safety risks associated with colloidal platinum
Solution Approach 1:
The patent modifies the chemical structure of platinum complexes by selecting specific carboxylic acid residues (non-aromatic C6-C18 or C8-C18 monocarboxylic acid residues, or non-aromatic C8-C18 dicarboxylic acid residues) and controlling the molecular structure of ligands L1 and L2, thereby changing the decomposition temperature parameter to enable low-temperature processing while maintaining safety by eliminating colloidal platinum
Solution Approach 2:
The patent uses stable, non-colloidal platinum complexes that can be decomposed completely at lower temperatures to form platinum layers, replacing the need for stable colloidal platinum or nanoplatinum materials that require high temperatures and pose safety risks
2Manufacturing precision
If existing platinum complexes are used for producing platinum layers, then platinum deposition is achieved, but the process requires high temperatures that damage temperature-sensitive substrates
Solution Approach 1:
The patent changes the chemical parameters of the platinum complex by specifying particular carboxylic acid residues and ligand structures, which lowers the decomposition temperature to enable processing on temperature-sensitive substrates while maintaining homogeneous platinum layer formation with mirror-like quality
3Stability of the object's composition
If platinum complexes with aromatic carboxylic acid residues are used, then stable complexes are formed, but they decompose at higher temperatures unsuitable for temperature-sensitive substrates
Solution Approach 1:
The patent changes the parameter of carboxylic acid residue type from aromatic to non-aromatic (specifically C6-C18 or C8-C18 monocarboxylic acids or C8-C18 dicarboxylic acids), which maintains sufficient complex stability for handling and deposition while lowering the decomposition temperature to below 200°C for compatibility with temperature-sensitive substrates
