新合成了不对称多环吩嗪类D-pi-A荧光染料的结构异构体，并在溶液和聚合物膜中进行了表征。在1，4-二氧六环中，染料在328-401 nm和516-532 nm附近有两个强吸收带，在595-629 nm附近有一个强荧光带(phi=0.32-0.84)。染料掺杂聚合物薄膜具有良好的波长转换能力，能够有效地将紫外光和绿黄光转换为红光(phi=0.43-0.86)。此外，还考察了染料掺杂PS的光稳定性。PMMA。中国人民解放军电影公司也受到了调查。(C)2011爱思唯尔B.V.保留所有权利。
Structural isomers of unsymmetric polycyclicphenazine-type D-pi-A fluorescent dyes have been newly synthesized and characterized in both solution and polymer films. The dyes exhibited two strong absorption bands at around 328-401 rim and 516-532 nm, and an intense fluorescence band at around 595-629 nm (phi = 0.32-0.84) in 1,4-dioxane. The dye-doped polymer films showed good ability of wavelength conversion; the films can efficiently convert ultraviolet and green-yellow lights into red light (phi=0.43-0.86). Moreover, the photostability of the dyes-doped PS. PMMA. and PLA films has been investigated. (C) 2011 Elsevier B.V. All rights reserved.
