Embodiment 1

[0028] 1) Substrate surface treatment: Soak the polymer substrate in 45% isopropanol aqueous solution for 30 minutes, then soak it in 2mol / L sulfuric acid at 55°C for 15 minutes, then wash it with water, dry it in vacuum at 60°C, and put it on the polymer substrate Carboxyl groups are introduced into the surface to obtain carboxylated substrates;

[0029] 2) Prepare an aqueous solution of bis(5,10,15,20-tetra-p-aminophenylporphyrin) with La: dissolve bis(5,10,15,20-tetra-p-aminophenylporphyrin) with La in water, Obtaining a concentration of 2g / L bis(5,10,15,20-tetra-p-aminophenylporphyrin) La aqueous solution;

[0030] 3) Microcontact printing: Soak the PDMS stamp in di(5,10,15,20-tetra-p-aminophenylporphyrin) and La aqueous solution for 30s, take it out and put it in N 2 Dry in airflow for 30s, put the PDMS stamp coated with bis(5,10,15,20-tetra-p-aminophenylporphyrin) La aqueous solution on the carboxylated substrate, press lightly for 10s, and transfer the PDMS stamp patte...

Embodiment 2

[0034] 1) Substrate surface treatment: Soak the polymer substrate in 55% isopropanol aqueous solution for 60 minutes, then soak it in 3mol / L sulfuric acid at 65°C for 20 minutes, then wash it with water, dry it in vacuum at 65°C, and place it on the polymer substrate Carboxyl groups are introduced into the surface to obtain carboxylated substrates;

[0035] 2) Prepare an aqueous solution of bis(5,10,15,20-tetra-p-aminophenylporphyrin) with La: dissolve bis(5,10,15,20-tetra-p-aminophenylporphyrin) with La in water, Obtaining a concentration of 5g / L bis(5,10,15,20-tetra-p-aminophenylporphyrin) La aqueous solution;

[0036] 3) Microcontact printing: Soak the PDMS stamp in di(5,10,15,20-tetra-p-aminophenylporphyrin) and La aqueous solution for 40s, take it out and put it in N 2 Dry in airflow for 60s, cover the PDMS stamp coated with bis(5,10,15,20-tetra-p-aminophenylporphyrin) La aqueous solution on the carboxylated substrate, press lightly for 20s, and transfer the PDMS stamp p...

Abstract

The invention relates to a water-soluble double-sandwich-type La metalloporphyrin complex. The invention also provides an application of the water-soluble double-sandwich-type La metalloporphyrin complex in a micro-contact printing technique. Metal patterns are prepared on the surface of a polymer substrate frequently used in the electronic industry by adopting an aqueous solution of bis(5,10,15,20-tetra-p-amino phenyl porphyrin)-La complex as micro-contact printing ink and a novel idea is provided for micro-contact printing industry.

Description

technical field [0001] The invention belongs to the field of modern electronic technology, and particularly relates to the application of a water-soluble double-layer sandwich-type La metalloporphyrin complex as a green environmental protection ink in micro-contact printing technology. Background technique [0002] Surface micro-structuring technology is gradually showing important application value, especially micro-contact printing technology, which can be micro-patterned on a small scale, which is of great significance in many fields, especially in the field of modern electronic technology. At present, there are few microcontact printing inks to choose from, and the materials that can be printed on the surface are limited. A large number of materials cannot be prepared with surface patterns by microcontact printing. Therefore, it is of great significance to develop new and stable inks. [0003] The applicant disclosed eight (octyloxy)-phthalocyanine zinc in the authorize...
