Abstract

The present invention includes fused tetraphenylene compounds that may be used as charge transporters, hosts or emitters in OLEDs.

First claim

We claim:

1. A compound having Formula I:

wherein X 1 -X 16 are each independently selected from the group consisting of CR and N;
wherein at least two adjacent X 1 -X 16 are CR;
wherein each R is independently selected from the group consisting of hydrogen, deuterium, halide, alkyl, haloalkyl, cycloalkyl, heteroalkyl, arylalkyl, alkoxy, thioalkoxy, aryloxy, thioaryloxy, amino, arylamino, diarylamino, carbazolyl, silyl, halosilyl, alkenyl, cycloalkenyl, heteroalkenyl, alkynyl, aryl, heteroaryl, acyl, carbonyl, carboxylic acids, ester, nitrile, isonitrile, sulfanyl, sulfonyl, phosphino, and combinations thereof;
wherein at least one pair of adjacent Rs is

 or is fused with two or more aromatic rings such that no acene unit of more than 3 fused rings is formed;
wherein in Attachments A and B, Y 1 -Y 2 , Y 2 -Y 3 , Y 3 -Y 4 , Y 4 -Y 5 and Y 5 -Y 6 are connected by single or double bonds;
wherein Y 1 -Y 6 are each independently selected from the group consisting of C and N;
wherein any unsaturated C in Y 1 -Y 6 is substituted by one or two R 1 ;
wherein in Attachment A, Z 1 and Z 2 are each independently selected from the group consisting of C═CR 2 R 3 , C═NR 2 , O, SO, SO 2 , BR 2 , PR 2 , SiR 2 R 3 , and Se;
wherein in Attachment B, Z 1 and Z 2 are each independently selected from the group consisting of CR 2 R 3 , C═CR 2 R 3 , C═O, C═NR 2 , NR 2 , O, S, SO, SO 2 , BR 2 , P, SiR 2 R 3 , and Se;
wherein in Attachment C, at least one of Y 1 -Y 4 is N;
wherein R 1 -R 3 are each independently selected from the group consisting of hydrogen, deuterium, halide, alkyl, haloalkyl, cycloalkyl, heteroalkyl, arylalkyl, alkoxy, thioalkoxy, aryloxy, thioaryloxy, amino, arylamino, diarylamino, carbazolyl, silyl, halosilyl, alkenyl, cycloalkenyl, heteroalkenyl, alkynyl, aryl, heteroaryl, acyl, carbonyl, carboxylic acids, ester, nitrite, isonitrile, suifanyl, sulfinyl, sulfonyl, phosphino, and combinations thereof; and
wherein

 is excluded.

2. The compound of claim 1 , wherein X 1 -X 16 are CR.

3. The compound of claim 1 , wherein X 1 -X 16 are CR and in Attachments A and B, Y 1 -Y 6 are C.

4. The compound of claim 1 , wherein at least two pairs of adjacent Rs are attachment A, B, C, or are fused with two or more aromatic rings such that no acene unit of more than 3 fused rings is formed.

5. The compound of claim 1 , wherein at least three pairs of adjacent Rs are attachment A, B, C, or are fused with two or more aromatic rings such that no acene unit of more than 3 fused rings is formed.

6. The compound of claim 1 , wherein at least four pairs of adjacent Rs are attachment A, B, C, or are fused with two or more aromatic rings such that no acene unit of more than 3 fused rings is formed.

7. The compound of claim 1 , wherein the compound is selected from the group consisting of:

wherein X 1 -X 22 are each independently selected from the group consisting of CR and N.

8. The compound of claim 1 , wherein the compound is selected from the group consisting of:
