CMS College Junction, CMS College Road, Kerala 686001. Dr. Mahesh Hariharan IISER Thiruvananthapuram, Maruthamala P O, Vithura, Thiruvananthapuram, Kerala 695551 A new perylene diimide (PDI) ligand (1) functionalized with a dipicolylethylenediamine (DPEN) moiety was synthesized and first used as a colorimetric and fluorometric dual-channel sensor to specifically detect the presence of Cu2+ over a wide range of other cations. The solution of 1 (10 μmol/L) upon addition of Cu2+ displayed distinguishing pink color compared with other cations including K+ Bis-Dithiano Perylene Diimide: Synthesis and Characterization of a Novel Ring System Russell A. Cormier and Brian A. Gregg Our findings demonstrate that bromo substituents at the bay positions of perylene diimides are readily displaced under very mild conditions by potassium thioacetate resulting in the subject dithiane annulations.

It is nearly insoluble in water. It is a member of a group of chemicals called polyaromatic hydrocarbons (PAHs). Perylene is a substance that occurs as a result of incomplete burning. It is found in coal, oil and gas.

Thin films of nanocrystalline 3,4,9,10-perylene-tetracarboxylic-diimide (PTCDI) were prepared on quartz substrates by thermal evaporation technique. The structural properties were identified by transmission electron microscopy (TEM) and the X-ray diffraction (XRD). The optical properties for the films were investigated using spectrophotometric measurements of the transmittance and reflectance The rates of exciton transfer within dyads of perylene diimide and terrylene diimide connected by oligophenylene bridge units have been shown to deviate significantly from those of Förster’s resonance energy transfer theory, according to single molecule spectroscopy experiments.

IDENTIFICATION: Perylene is a yellow to colorless crystalline or plate-like solid. It is nearly insoluble in water. It is a member of a group of chemicals called polyaromatic hydrocarbons (PAHs). Perylene is a substance that occurs as a result of incomplete burning. It is found in coal, oil and gas.

Perylene diimide derivatives were developed as industrial dyes due to their excellent chemical, photo, thermal, and weather stability. Nowadays, perylene dyes 18 Aug 2013 A combination of CC homocoupling and CH activation doubles the yields of perylenediimide dimers.
