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.

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.
