Abstract

The invention discloses a method for applying a water-soluble zinc porphyrin complex to microcontact printing. The method comprises the following specific steps of: 1) substrate carboxylation; 2) preparation of 5,10,15,20-tetra[4-(3'-propoxy pyridine bromide)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[4-(3'-propoxy pyridine bromide)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 porphyrin zinc complex in micro-contact printing. Background technique [0002] Microcontact printing is a technique for surface patterning of materials that has developed rapidly in recent years. Compared with other printing technologies, microcontact printing has the advantages of being fast and cheap, and has the characteristics of flexible and changeable operation methods. At present, there are few printing agents to choose from, and most of them use organic solvents to prepare printing agent solutions, which is not environmentally friendly enough. Therefore, it is of great significance to develop a stable and green printing agent. [0003] Porphyrin compounds can form complexes with many metal ions, and there are many types of complexes. At present, porphyrin metal complexes have been widely used in many fields such...
