The aim of this
article is to inform about perylene-3,4,9,10-tetracarboxylic acid dimide (PDI)
derivatives. Also, it is to give short and simple information about optical
properties and using fields. Perylene-3,4,9,10-tetracarboxylic acid dimide
derivatives known as perylene diimides are material
of highly conjugated molecule. PDIs exhibit strong absorptions within
the range of 400-450 nm (B band) and 500-700 nm (Q band). Perylene diimide dyes show generally characteristic
absorption peaks at 458, 490, 526 nm. These absorption peaks are matched by the
corresponding emission peaks at 540, 576, 624 nm, respectively. It has donor
core and acceptor carbonyl groups. Perylene dimide has good electron
mobility, high fluorescence quantum yields, strong absorption in the visible
region, photostability, thermal
stability, good semi-conductivity. These properties
benefit them application of electronic material. Applications of PDIs are in
the field of photo-electronic material, dye lasers, organic light-emitting diodes,
and chemosensing materials.
