Embodiment 1

[0110] This example describes porphyrin-(phenyl-perylenediimides) represented by general structure I comprising fragments represented by structures 6 and 35 (Tables 1 and 5) 4 - compound (TPP-PD I 4 ) synthesis method,

[0111]

[0112] The method includes several steps.

[0113] In the first step, the synthesis of 1,7-dibromobi-3,4:9,10-tetracarboxylic dianhydride represented by the general structure 81 is carried out:

[0114]

[0115]

[0116] To this end, 3,4:9,10-perylenetetracarboxylic dianhydride (28.52 g, 72.7 mmol) was added to 420 ml of concentrated sulfuric acid and stirred at 55° C. for 24 hours. Iodine (0.685 g, 2.70 mmol) was added to the reaction mixture and stirred at 55°C for an additional 5 hours. Bromine (8.3ml, 162mmol) was added dropwise to the reaction flask over 1 hour and stirred at 85°C for 24 hours. Then with nitrogen N 2 Replace excess bromine. Water (66ml) was added dropwise to the cooled mixture and the precipitate was filtered off. ...

Abstract

The present disclosure provides an energy storage molecular material, crystal dielectric layer and capacitor which may solve a problem of the further increase of volumetric and mass density of reserved energy associated with some energy storage devices, and at the same time reduce cost of materials.

Description

Background technique [0001] A capacitor is a passive electronic component used to store energy in the form of an electrostatic field and includes a pair of electrodes separated by a dielectric layer. When there is a potential difference between the two electrodes, an electric field exists in the dielectric layer. An ideal capacitor is characterized by a single constant value of its capacitance. It is the ratio of the charge on each electrode to the potential difference between them. In fact, the dielectric layer between the electrodes is capable of passing a small amount of leakage current. The electrodes and leads introduce an equivalent series resistance, and the dielectric layer places a limit on the electric field strength that leads to the breakdown voltage. The simplest energy storage device consists of two parallel electrodes separated by a dielectric layer with a dielectric constant ε, each electrode having an area S and arranged at a distance d from each other. Th...
