Problems solved by technology

A significant disadvantage of this class of compounds is therefore that the molecule dissociates with bond breaking and the two halves of the molecule are irreversibly separated from each other in space
Separation process can limit component life

[0077] I. Synthesis

[0078] I.A) Two-step synthesis of 2,2',6,6'-tetraphenyl-4,4'-dipyran (GBP)

[0079] GBP is synthesized in two stages.

[0080] I.A-1) Synthesis of perchloric acid diphenylpyrrolium salt (diphenylpyrylium perchlorate)

[0081] 30g of acetophenone (0.25mol) was dissolved in 250g of ethyl orthoacetate (1.68mol) and boiled. Then 18 g of 70% perchloric acid (0.13 mol) was slowly added dropwise to the solution. The temperature was lowered to 80 °C and the reaction was continued overnight. After cooling, the precipitate formed was filtered off with suction and washed with diethyl ether. This gave a reaction product of bisphenylpyrrolium perchlorate having a melting point of 222° C. according to the following reaction formula.

[0082]

[0083] I.A-2) Synthesis of 2,2',6,6'-tetraphenyl-4,4'-dipyran (GBP)

[0084] Heat 0.2 mol of bisphenylpyrrolium perchlorate in pyridine and 0.01 mol of triphenylphosphine under reflux for 3 hours. After cooling, the pre...

Abstract

The invention relates to an organic electron transport layer n-dopant, the use of said n-dopant to construct organic electronic components, transistors, organic light-emitting diodes, light-emitting electrochemical cells, organic solar cells, photodiodes, and electronic components containing said n-dopant.

Description

technical field [0001] The present invention relates to a novel n-type doped material as an electron transport layer, and relates to the use of these compounds in the construction of organic electronic components, transistors, organic light-emitting diodes, light-emitting electrochemical cells, organic solar cells, photodiodes and electronic components containing these compounds use in . Background technique [0002] Organic electronic components consist at least partially of organic materials or organic compounds which can have both well-known insulator properties as well as electrically conductive or semiconductive properties. The properties and functions of organic electronic components such as organic solar cells, transistors, light-emitting elements and photodiodes depend essentially on the configuration of the components used. Organic electronic components usually have transport layers of p-conductivity (hole conductivity) or n-conductivity (electron conductivity), so...
