Abstract

The invention provides a polycyclic aromatic compound or a salt thereof having a partial structure represented by the following general formula (I):

wherein X, ring A, ring B, ring C, and ring D are as defined in the specification.

First claim

The invention claimed is:

1. A polycyclic aromatic compound or a salt thereof represented by the following formula (I):

wherein
X represents B, P, P═O, P═S, P═Se, As, As═O, As═S, As═Se, Sb, Sb═O, Sb═S, Sb═Se, an optionally substituted metal in groups 3 to 11 in the periodic table, or an optionally substituted metal or metalloid in group 13 or 14 of the periodic table; and
ring A, ring B, ring C, and ring D are the same or different, and each represents an optionally substituted phenyl ring, an optionally substituted phenyl ring fused to an aryl or heteroaryl ring, an optionally substituted heteroaromatic ring, or an optionally substituted heteroaromatic ring fused to an aryl or heteroaryl ring,
wherein at least one of ring A, ring B, ring C, and ring D is an optionally substituted heteroaromatic ring, or an optionally substituted heteroaromatic ring fused to an aryl or heteroaryl ring,
wherein the heteroaromatic ring of ring A, ring B, ring C, and ring D is selected from the group consisting of thiophene, pyrrole and pyridine, and
wherein the compound represented by formula (I) is not a heterofullerene.

2. The polycyclic aromatic compound or salt thereof according to claim 1 , represented by the following formula (II):

wherein
Y a s are the same or different, and each represents C— or N; or two adjacent Y a s on the same ring, together with a bond therebetween, form N—, or S; provided that all Y a s do not represent C— at the same time; and
X represents B, P, P═O, P═S, P═Se, As, As═O, As═S, As═Se, Sb, Sb═O, Sb═S, Sb═Se, an optionally substituted metal in groups 3 to 11 in the periodic table, or an optionally substituted metal or metalloid in group 13 or 14 of the periodic table.

3. The polycyclic aromatic compound or salt thereof according to claim 1 , represented by any one of the following formulae (II-2) to (II-54):

wherein
X represents B, P, P═O, P═S, P═Se, As, As═O, As═S, As═Se, Sb, Sb═O, Sb═S, Sb═Se, an optionally substituted metal in groups 3 to 11 in the periodic table, or an optionally substituted metal or metalloid in group 13 or 14 of the periodic table; and
Z represents S, or N—.

4. The polycyclic aromatic compound or salt thereof according to claim 1 represented by the following formula (II′):

wherein
Ys are the same or different, and each represents CR or N; or two adjacent Ys on the same ring, together with a bond therebetween, form NR, or S; provided that all Ys do not represent C— at the same time;
X represents B, P, P═O, P═S, P═Se, As, As═O, As═S, As═Se, Sb, Sb═O, Sb═S, Sb═Se, an optionally substituted metal in groups 3 to 11 in the periodic table, or an optionally substituted metal or metalloid in group 13 or 14 of the periodic table;
