Abstract

Embodiments in accordance with the present invention relate generally to formulations for use in organic semiconductor layers of organic electronic devices, and more specifically in organic field effect transistors, to organic semiconductor layers prepared from such formulations, and to organic electronic devices and organic field effect transistors encompassing such organic semiconductor layers.

First claim

We claim:

1. A formulation comprising an organic semiconductor (OSC) and a polycycloolefinic polymer comprising one or more pendant reactive groups.

2. The formulation according to claim 1 , wherein the reactive group comprises a hydroxyl portion or an olefinic portion that can crosslink with Parylene.

3. The formulation according to claim 1 , wherein the polycycloolefinic polymer is a norbornene-type polymer having one or more distinct types of repeating units of Formula I

wherein Z is selected from —CH 2 —, —CH 2 —CH 2 — or —O—, m is an integer from 0 to 5, each of R 1 , R 2 , R 3 and R 4 are independently selected from H, a C 1 to C 25 hydrocarbyl, a C 1 to C 25 halohydrocarbyl or a C 1 to C 25 perhalocarbyl group, and wherein in at least one repeating unit one or more of R 1-4 denote or comprise a reactive group.

4. The formulation according to claim 1 , wherein the polycycloolefinic polymer comprises one or more repeating units selected from the following formulae

where Y is alkyl or alkoxy with 1 to 20 C atoms or alkylcarbonyl with 2 to 20 C atoms, n is an integer from 0 to 8, a and b are independently of each other an integer from 0 to 7, wherein a+b≦7, and c and d are independently of each other 0 or 1.

5. The formulation according to claim 4 , wherein the polycycloolefinic polymer comprises one or more repeating units selected from the following formulae

where n1 is 0, 1, 2, 3, 4 or 5, a and b are independently of each other an integer from 0 to 7, and wherein a+b≦7.

6. The formulation according to claim 4 , wherein the polycycloolefinic polymer comprises one or more repeating units selected from the following formulae
