The invention describes the use of polyphenols and polyamino derivatives adjacent to absorber layers on the basis of small molecules in organic optoelectronic components.

Polyphenols and polyamino derivatives in organic optoelectronic components

Compounds of formula (Ia) and/or formula (Ib), are disclosed wherein R1 and R3 are independently selected from the group consisting of H, halogen, alkyl, fluorinated or partly fluorinated alkyl, and heteroaryl, R2 is selected from the group consisting of halogen, fluorinated and partly fluorinated alkyl, R4 and R5 are independently selected from the group consisting of halogen, alkyl, fluorinated or partly fluorinated alkyl, alkenyl, alkinyl, alkoxy, aryl, and heteroaryl, Z is independently selected from the group consisting of CH, CHR6 or CR7R8, with R6, R7 and R8 independently selected from the group consisting of H, halogen, alkyl, alkoxy, aryl, and heteroaryl, wherein n is independently 1, 2 or 3, U, V and W of formula (Ia) independently form an aryl ring or a heteroaryl ring, and T, U, V and W of formula (Ib) form an aryl ring or a heteroaryl ring.

Chemical compounds, optoelectronic elements comprising at least one new chemical compound, and use of new chemical compounds in an optoelectronic element

New absorbing materials of formula (I) for use in organic semiconducting components: 

Organic semiconducting material and its synthesis and organic semiconducting component with the material

A compound of a formula EWG1-(T1)-(T2)-(Z)-(T3)-(T4)-EWG2 capable of use as a functional component in organic electronic devices, which enable improved absorption in organic solar cells or have an increased charge carrier mobility.

Organic semiconducting material and use thereof in organic devices

An optoelectronic component includes a photoactive layer which is arranged between an electrode and a counter electrode. In addition to a donor-acceptor system, the photoactive layer includes a third material which influences the crystallization of the donor-acceptor system. The third material selected from a group consisting of crown ethers, triphenyls, sorbitols, quinacridones and bis(4-(tert-butyl)benzoato-O) hydroxyaluminium. Crown ethers are especially preferred.

Optoelectronic component

A compound and method of producing the compound of formula (I) that has high absorption in the short wavelength spectral region of visible light and is capable of being used for an organic electronic component.

Compound for photoactive organic electronic components and photoactive organic electronic component containing the compound

A semiconductive component with a layer system includes at least one layer comprising a compound of the general formula (I) or (II). 

Organic semiconductive component

The invention relates to compounds of general formula IIIa and their use in optoelectronic components. 

Evaporable organic semiconductive material and use thereof in an optoelectronic component
