Usage

General Description

Perylene, 3,10-dibromo- is a synthetic and highly aromatic hydrocarbon compound that belongs to the family of polycyclic aromatic hydrocarbons (PAHs). It is characterized by a large, rigid, and planar structure, with two bromine atoms substituted at positions 3 and 10. Perylene, 3,10-dibromo- is commonly used as a fluorescent dye in the manufacturing of organic light-emitting diodes (OLEDs), solar cells, and electronic devices. It is also utilized as a molecular probe in biological research and as a chemical intermediate in the synthesis of other compounds. However, due to its high persistence and potential environmental and health risks, its usage and emissions are regulated in many countries to minimize its impact on ecosystems and human health.

Reliable and reproducible separation of 3,9-and 3,10-dibromoperylenes and the photophysical properties of their alkynyl derivatives

We developed a reliable and reproducible method for the separation of 3,9-dibromoperylene and 3,10-dibromoperylene resulting from bromination of perylene by using sequential and repeated recrystallization. Because of the unprecedented purities of the dibromoperylenes, they exhibit the high-est melting temperatures so far reported. In addition, various alkynylperylenes were prepared from the dibromoperylenes, and we investigated the photophysical characteristics of these alkynyl derivatives in detail.

Lateral Fusion of Chemical Vapor Deposited N = 5 Armchair Graphene Nanoribbons

Bottom-up synthesis of low-bandgap graphene nanoribbons with various widths is of great importance for their applications in electronic and optoelectronic devices. Here we demonstrate a synthesis of N = 5 armchair graphene nanoribbons (5-AGNRs) and their lateral fusion into wider AGNRs, by a chemical vapor deposition method. The efficient formation of 10- and 15-AGNRs is revealed by a combination of different spectroscopic methods, including Raman and UV-vis-near-infrared spectroscopy as well as by scanning tunneling microscopy. The degree of fusion and thus the optical and electronic properties of the resulting GNRs can be controlled by the annealing temperature, providing GNR films with optical absorptions up to ～2250 nm.
