摘要：
Highly efficient luminescence dyes based on pyrene and anthracene derivatives (see figure) are synthesized for liquid crystal dye lasers. The threshold value of one of the pyrene derivatives is as low as 1/20 that of the commonly used DCM in cholesteric liquid crystal (CLC) distributed feedback lasers. Good optical properties such as luminous efficiency and solubility in CLCs are important factors for realizing a low threshold. © 2010 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
