Perylene tetracarboxylic dianhydride

The customary method of preparing perylene pigments is by reaction of perylene tetracarboxylic dianhydride with primary aliphatic or aromatic amines in a high boiling solvent. The dianhydride itself is also used as a pigment. Di-methylperylimide may also be obtained by treating the diimide with methyl chloride or dimethyl sulfate. 

Pyrolysis of a perylene-tetracarboxylic dianhydride monomer above 520 C resulted in vapor-phase condensation of poly-peri-naphthalene (PPN), a representative one-dimensional graphite polymer. PPN was obtained as fine whiskers with rectangular cross sections and exhibited electrical conduction behaviors characteristic of low-dimensional disordered systems. At HTT s above 2800 C,...

Figure 14-20. Molecular structure of naphthalene tetracarboxylic dianhydride (NTCDA) and perylene tetracarboxylic dianhydride (PTCDA).

Another interesting feature in the data given in Table 14-3 is the different mobility reported for NTCDA (naphthalene tetracarboxylic dianhydride) and PTCDA (perylene tetracarboxylic dianhydride). These two compounds present very similar molecular formulae (Fig. 14-20), but differ by their crystal packing... 

Perylene tetracarboxylic dianhydride and 3,4,9,10-Perylene tetracarboxylic diimide... 

Indeed, besides the perylene tetracarboxylic dianhydride (PTDA) used by Lee et al. [54] and the bisimide dianhydride synthesized by Kim [55], only two new naphthalenic dianhydrides have been described. In this respect, 4,4 -ketone dinaphthalene l,l, 8,8 -tetracarboxyUc dianhydride (KDNTDA, Fig. 3) is obtained through a multistep synthesis, with a 19% overall yield [56].
