Abstract: A series of 3, 6-dinitrodibenzopyrioindium heterocyclic compounds with different heteroatoms were synthesized, and the chemical shifts of their aromatic carbons are assigned by 13C-1H COSY spectroscopy.The effect of different heteroatoms to the chemical shifts of the aromatic carbonatoms are discussed too.

Key words: 3,6-dinitrodibenzopyrioindium heterocyclic compounds, Shield effects, Deshield effects, Heavy atoms effects
