Embodiment 1

[0061] (Manufacture of porous coordination polymers)

[0062] Add 0.24 g of iron ammonium sulfate (II) hexahydrate, 0.1 g of L-ascorbic acid, and 0.15 g of potassium tetracyanonickelate (II) monohydrate to 240 mL of a mixed solvent of distilled water and ethanol in a Erlenmeyer flask, and stir , recovering the precipitated intermediate particles. 0.1 g of the obtained intermediate particles were dispersed in ethanol, and 0.10 g of pyrazine was added over 30 minutes. The deposited precipitate was filtered and dried at 120° C. for 3 hours in the air to obtain an orange porous coordination polymer.

[0063] (Manufacture of gas detection sheet)

[0064] After immersing the porous coordination polymer of Example 1 in acetonitrile at 25° C. for 10 hours, suction filtration was performed using filter paper 5 types C and dried, thereby obtaining a purple-red color on filter paper 5 types C. Porous coordination polymers. The spin state of the obtained purple-red porous coordination...

Abstract

A gas detection sheet wherein a porous coordination polymer represented by formula (1) is supported on a supporter and the air permeability of the gas detection sheet is 0.8 seconds or more and 60 seconds or less.Fex(pz)[Ni1-yMy(CN)4] (1)(wherein, pz=pyrazine, X ranges from 0.95 to 1.05, M=Pd or Pt, and y ranges from 0 to 0.15).

Description

technical field [0001] The present invention relates to a gas detection sheet and an electrochemical element provided with the gas detection sheet. Background technique [0002] Along with the miniaturization and higher functionality of portable electronic devices in recent years, further miniaturization, weight reduction, and higher capacity of electrochemical elements are expected. [0003] Electrochemical elements can be produced in various forms, and representative examples include angular, cylindrical, and pouch shapes. [0004] Among them, the pouch-type electrochemical element can be manufactured into light and various forms due to the use of a pouch-shaped case formed of thin sheets such as aluminum composite films, and has the advantage that the manufacturing process is also simple. There is a problem that expansion is easy to occur due to damage or increase in internal pressure compared with the square or angle type. [0005] In electrochemical components, a mixe...
