[4,5′-Biisobenzofuran]-1,1′,3,3′-tetrone（Cat No.:L017850）, also known as naphthalene-1,4,5,8-tetracarboxylic dianhydride (NTCDA), is an aromatic, planar, electron-deficient compound featuring two fused isobenzofuran rings connected through a biaryl linkage with four ketone groups forming two anhydride moieties. This tetracarboxylic dianhydride is widely used as a precursor in the synthesis of organic semiconductors, pigments, and high-performance polyimides. Its electron-accepting nature makes it valuable in organic electronics, including photovoltaic cells and field-effect transistors. The rigid, conjugated structure also supports π-π stacking interactions, making it useful for engineering optoelectronic materials and charge-transporting frameworks.
