Structural isomers of novel 2,10-disubstituted benzofuro[2,3-e]naphthoxazole fluorescent dyes have been synthesized. The phtophysical properties have been investigated in solution and in the solid state. The absorption and fluorescence intensities of the naphth[1,2-d]oxazoles are much stronger than those of the naphth[2,1-d]oxazoles in solution. Moreover, in the solid state, the emission intensities
合成了新型的2,10-二取代的苯并呋喃[2,3- e ]萘恶唑荧光染料的结构异构体。已经在溶液和固态下研究了植物的物理性质。的萘的吸收和荧光强度[1,2 d ]恶唑比那些吩[2,1-强得多d在溶液]恶唑。而且,在固态下,前者的发射强度通常比后者的异构体的发射强度强得多。为了了解光物理性质的差异,已进行了半经验分子轨道计算和X射线晶体学分析。
