Embodiment 1

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

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

[0030] 3) Micro-contact printing: Soak the PDMS stamp in an aqueous solution of bis(5,10,15,20-tetra-p-aminophenylporphyrin) and La for 30s, then remove it in N 2 Dry for 30s in air flow, and cover the PDMS seal coated with bis(5,10,15,20-tetra-p-aminophenylporphyrin) and La aqueous solution on the carboxylated substrate, press lightly for 10s to transfer the PDMS seal pattern ...

Embodiment 2

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

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

[0036] 3) Micro-contact printing: Soak the PDMS stamp in an aqueous solution of bis(5,10,15,20-tetra-p-aminophenylporphyrin) and La for 40s, and then place it in N 2 Dry for 60s in air flow, and cover the PDMS seal coated with bis(5,10,15,20-tetra-p-aminophenylporphyrin) with La aqueous solution on the carboxylated substrate, press lightly for 20s, and transfer the PDMS seal pa...

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 La metalporphyrin complex as a green ink in micro-contact printing technology. Background technique [0002] Surface micro-construction technology is gradually showing its important application value, especially micro-contact printing technology, which can be micro-patterned on a small size, and is of great significance in many fields, especially in the field of modern electronic technology. At present, there are few micro-contact printing inks available, which also limits the materials that can be micro-contact printing on the surface. A large number of materials cannot be used to prepare surface patterns by micro-contact printing. Therefore, the development of new and stable inks is of great significance. [0003] The applicant disclosed in the authorized patent (CN 102516841B) eight (octyloxy)-phthalocyan...
