Diazirine containing organic electronic compositions and device thereof

An organic electronic (OE) device comprising a dielectric layer, said dielectric layer comprising a polycycloolefinic polymer selected from the group consisting of:

• a) a polymer of formula (III):
• and
• b) a polymer of formula (IV):
• wherein
• each occurrence of R1, R2, R3 or R4 may be same or different and each independently is hydrogen or a hydrocarbyl selected from the group consisting of linear or branched (C1-C12)alkyl, (C3-C12)cycloalkyl, (C3-C12)cycloalkyl(C1-C12)alkyl, (C6-C12)bicycloalkyl, (C6-C12)bicycloalkyl(C1-C12)alkyl, (C7-C14)tricycloalkyl, (C7-C14)tricycloalkyl(C1-C12)alkyl, (C6-C10)aryl and (C6-C10)aryl(C1-C6)alkyl;
• and a compound of formula (V):
• wherein,
• L is a divalent linking or a spacer group selected from:
• —C(O)O—R7—OC(O)—, —C(O)O—R7—, —R7—OC(O)—R7—, —C(O)—R7—OC(O)—, —C(O)—R7—, —R7—C(O)—R7—, —O—R7—OC(O)—, —O—R7—O—, —O—R7—, —R7—O—R7—,
• —C(O)NH—(CH2)b—NH(CO)—, where b is 1 to 15, —C(O)NH—(CH2CH2O)c(CH2)d—NR5(CO)—, where c is 2 to 6 and d is 1 to 6, and each occurrence of R7 may be the same or different which is a divalent group independently selected from (C1-C12)alkyl, (C3-C12)cycloalkyl, (C6-C12)aryl, (C6-C12)aryl(C1-C12)alkyl, (C6-C10)heteroaryl, (C6-C10)heteroaryl(C1-C12)alkyl, —(CH2—CH2—O)a—, where a is an integer from 1 to 10;
• R5 and R6 are the same or different and each is independently selected from (C1-C12)alkyl, where portions of hydrogen on alkyl are replaced with fluorine, (C1-C12)perfluoroalkyl, (C6-C12)aryl, (C6-C12)aryl(C1-C12)alkyl, where portions of hydrogen on alkyl are replaced with fluorine, and (C6-C12)arylperfluoro(C1-C12)alkyl;
• and
• Ar1 and Ar2 are the same or different and each is independently selected from (C6-C12)arylene or (C6-C12)heteroarylene group optionally substituted with a group selected from halogen, —OH, (C1-C4)alkyl, (C1-C4)alkoxy, (C6-C10)aryl, (C6-C12)aryloxy, (C6-C12)aryl(C1-C4)alkyl and (C6-C12)aryl(C1-C4)alkyloxy.
