摘要：

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 highest 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.
