Perylenetetracarboxylic dianhydride (PTCDA) is an organic dye molecule and an organic semiconductor. It is used as a precursor to a class of molecules known as Rylene dyes, which are useful as pigments, dyes and organic semiconductors.

Structure

PTCDA consists of a perylene core to which two anhydride groups have been attached, one at either side. It occurs in two crystalline forms, α and β[2]. Both have the P21/c monoclinic symmetry and a density of ca. 1.7 g/cm3, which is relatively high for organic compounds. Their lattice parameters are:

Form a b c γ
α 0.374 nm 1.196 nm 1.734 nm 98.8°
β 0.378 nm 1.930 nm 1.077 nm 83.6°

Uses

Atomic force microscopy image of a single PTCDA molecule on Si at room temperature.[3]
Self-assembly of PTCDA molecules on NaCl, scanning tunneling microscopy image.[4]

As a chemical precursor

The main industrial use of PTCDA is as a precursor to Rylene dyes.[5][6]

As an organic semiconductor

PTCDA's relatively simple chemical structure makes it attractive as a model compound for the study of organic semiconductors. It has among others been used to create single-crystal OFETs[7] and organic solar cells[8]. It is also often used in the study of the interaction between organic semiconductors and the surfaces of metals[9], insulators[4] and inorganic semiconductors[3]. The application of PTCDA as an organic semiconductor is limited by it's low solubility in common solvents[10], which makes it unattractive for most industrial applications.
