  A process for preparing polymerizable biaryl derivatives comprises reacting an aromatic comprising a 6-membered ring which bears ester or benzylic OH groups in the 1,4 position with a second aromatic in a palladium-catalyzed cross-coupling reaction to give a biaryl and converting the ester or benzylic OH groups into polymerizable groups in one or more steps. The biaryls obtained are suitable for preparing polymers which are used as electroluminescence materials.

  A series of new 2,5-dibenzoxazolylphenols and related compounds was prepared by condensation of hydroxy- and methanesulfonamidoterephthalic acids with 2-aminophenols. These displayed excited state intramolecular proton-transfer fluorescence at room temperature and above with quantum yields as high as 0.48 and emission peaks of 492-517 nm. The methanesulfonamido group was found about as effective a

  羟基和甲磺酰胺基对苯二甲酸与2-氨基苯酚的缩合反应制备了一系列新的2,5-二苯并恶唑基苯酚和相关化合物。这些在室温及更高温度下显示出激发态的分子内质子转移荧光，量子产率高达0.48，发射峰为492-517 nm。发现甲磺酰胺基的质子供体与酚羟基一样有效。在某些情况下，将取代基结合到苯并恶唑基团上会增加氟在烃类溶剂中的溶解度，但会降低量子产率。这些氟作为闪烁检测介质中用于电离辐射的波长转换剂是令人关注的。
