Use of water-soluble tetra sodium sulfonate phenyl porphyrin metal complex in microcontact printing

Abstract

The invention discloses a method for applying a water-soluble tetra sodium sulfonate phenyl porphyrin metal complex to microcontact printing. The method comprises the following specific steps of: 1) substrate carboxylation; 2) preparation of 5,10,15,20-tetra sodium sulfonate phenyl zinc porphyrin water solution; 3) microcontact printing; and 4) chemical plating. The method has the beneficial effects that 1. the obtained pattern is exquisite and fine and a new thought is provided for the microcontact printing industry; and 2. as a printing agent, the 5,10,15,20-tetra sodium sulfonate phenyl zinc porphyrin water solution has water solubility, can reduce use of organic solvents, has the advantages of environment-friendliness, low cost and stability and has great potential in industrial application.

Description

technical field

[0001] The invention belongs to the field of modern electronic technology, and particularly relates to the application of a water-soluble sodium tetrasulfonate phenyl porphyrin metal complex in micro-contact printing. Background technique

[0002] With the development of modern science and technology, microcontact printing, as an excellent surface "soft engraving" technology, has developed rapidly in recent years. Compared with other printing technologies such as optical lithography, microcontact printing has many characteristics such as fast, cheap, and flexible operation methods. However, there are few microcontact printing agents to choose from at present, and most of them use organic solvents to prepare the printing agent solution, which is not environmentally friendly enough. Therefore, it is of great significance to develop a stable and green printing agent.

[0003] In recent years, scientists' research on sodium tetrasulfonate phenylporphyrin metal ...
