Specifications | MSDS | Literature and Reviews


2,6-Dibromonaphthalene-1,4,5,8-tetracarboxylic dianhydride (NTCDA-2Br, CAS number 83204-68-6) is a symmetric naphthalene derivative with adjacent carboxylic acids forming anhydride on both ends of the structure. It is a precursor to naphthalene diimides (NDIs) which are used as active layer materials in organic solar cells, field-effect transistors.

2,6-Dibromonaphthalene-1,4,5,8-tetracarboxylic dianhydride possesses aromatic planar conjugated structure and is favourable for good charge transport. Materials composed of naphthalene-1,4,5,8-tetracarboxylic dianhydride (NTDCA) or naphthalene-diimides (NDIs) have an excellent combination of redox, electrical, optical and thermal properties with high moisture and oxygen resistance.

2,6-Dibromonaphthalene-1,4,5,8-tetracarboxylic dianhydride on its own could be used as cathode interlayer materials for efficient electron extraction.
