270 results about "Tetrazine" patented technology

Tetrazine is an unstable compound that consists of a six-membered aromatic ring containing four nitrogen atoms with the molecular formula C₂H₂N₄. The name tetrazine is used in the nomenclature of derivatives of this compound. Three core-ring isomers exist: 1,2,3,4-tetrazines, 1,2,3,5-tetrazines, and 1,2,4,5-tetrazines, also known as v-tetrazines, as-tetrazines and s-tetrazines respectively.

Electrode electrolyte for use in solid polymer fuel cell

This invention provides an electrode electrolyte for a solid polymer-type fuel cell, in which a cost problem and a problem related to recovery of catalyst metals are solved, having excellent proton conductivity, dimensional stability and heat resistance.
An electrode electrolyte for a solid polymer electrolyte-type fuel cell contains a polymer, which has a polyphenylene structure as a main chain and both a sulfonic acid group and a nitrogen-containing heterocyclic group as a side chain. A side chain having the nitrogen-containing heterocyclic group has a structure represented by the following general formula (D).
(In formula, Z represents at least one kind of structures selected from a group consisting of a direct bond, —O— and —S—, Y represents at least one kind of structures selected from a group consisting of —CO—, —SO2—, —SO—, —CONH—, —COO—, —(CF2)1— (1 is an integer of 1 to 10) and —C(CF3)2— and R20 represents a nitrogen-containing heterocyclic group. q represents an integer of 1 to 5 and p represents an integer of 0 to 4.)
The above nitrogen-containing heterocyclic group is at least one kind of group derived from a compound selected from the group consisting of nitrogen-containing heterocyclic compounds including pyrrole, thiazole, isothiazole, oxazole, isoxazole, pyridine, imidazole, imidazoline, pyrazole, 1,3,5-triazine, pyrimidine, pyridazine, pyrazine, indole, quinoline, isoquinoline, purine, benzimidazole, benzoxazole, benzothiazole, tetrazole, tetrazine, triazole, carbazole, acridine, quinoxaline and quinazoline and derivatives thereof.
