Embodiment 1

[0055] A hydrogen-bonded cross-linked intrinsically stretchable conductive polymer based on EDOT oligomers, prepared by the following steps:

[0056] (1) Synthesis of stretchable group N2, N6-bis(2-(5-(tributyltin)thiophene)ethyl)pyridine-2,6-dicarboxamide (SnBu 3 -PDCA-SnBu 3 ):

[0057]

[0058] 1a) Dissolve 2,6-pyridinedicarboxylic acid (5.00g, 30mmol) in the raw material, add dropwise oxalyl chloride (11.43g, 90mmol) at 0°C, after the addition is complete, raise the temperature of the solution to 25°C, and stir to form 2,6-pyridine dicarboxylic acid chloride, the yield is 95%;

[0059] 1b) The resulting 2,6-pyridinedicarboxylic acid chloride (6.00 g, 360 mmol) and 2-thienylethylamine (12.00 g, 640 mmol) were dissolved in triethylamine (5 mL) and CH 2 Cl 2 (40mL) in a mixed solution, react at room temperature to generate N2, N6-bis(2-(thiophen-2-yl)ethyl)pyridine-2,6-dicarboxamide (PDCA), which is obtained after separation and purification with a silica gel column w...

Abstract

The invention discloses a novel hydrogen bond cross-linked stretchable conductive polymer and a synthesis method, belonging to the technical field of polymer synthesis. The above-mentioned novel hydrogen-bonded cross-linked stretchable conductive polymer includes a hydrogen-bonded cross-linked stretchable group and a functional conductive group; the hydrogen-bonded cross-linked stretchable group is a nitrogen-containing heterocycle; the The functional conductive groups are oligomers of 3,4-dioxyethylenethiophenes (EDOT), thiophenes, selenophenes and pyrroles and their derivatives. The novel hydrogen bond cross-linked stretchable conductive polymer prepared by the invention is based on the intrinsic stretchable group as the core, so that the polymer has good stretchable self-healing properties.

Description

technical field [0001] The invention relates to the technical field of polymer synthesis, in particular to a novel hydrogen bond cross-linked stretchable conductive polymer and a synthesis method. Background technique [0002] Since the research team of Mac Diarmid, a chemist at the University of Pennsylvania, first discovered that doped polyacetylene (PA) has metal-like conductivity in 1976, people have deepened their understanding of the structure and understanding of conjugated polymers. Improvement, the birth of a new interdisciplinary discipline of conductive polymers. In subsequent studies, conductive polymers such as polypyrrole, polyparaphenylene, polyphenylene sulfide, polythiophene, and polyaniline were gradually discovered. The special structure and excellent physical and chemical properties of conductive polymers make it a research hotspot in materials science. As one of the irreplaceable emerging basic organic functional materials, conductive polymer materials ...
