Applications, photoconductors pigments

Tetrapyrroles contain an extended jt-conjugated system which is responsible for their use in a wide range of applications ranging from technical (pigments, catalysts, photoconductors) to medicinal (photodynamic therapy) uses. The electronic absorption spectra are governed by the aromatic 18 tt-electron system and typically consist of two main bands. In phthalocyanines the Q band around 660-680 nm is the most intense one accompanied by a weaker Soret band near 340 nm . In porphyrins the situation is reversed with an... [Pg.192]

A comparison of perylene patents and review articles over the last twenty years clearly indicates the importance and potential for perylene-based pigments, dyestuffs and their derivatives in non-traditional applications such as electrophotographic photoconductors, laser dyes, and fluorescent probes . ... [Pg.259]
