Pd-catalyzed cyclization of a fluorescent dimer in which two cores of the potent estrogenic estradiol are bridged by the 1,4-diethynil benzene moiety led to a steroid dimer bearing the 1,4-di(benzofuran-2-yl)benzene. The obtained compound showed an intense blue fluorescence characterized by a broad emission band between 350 and 550 nm, with four maxima at 384, 403, 435, and 456 nm. The benzofuran dimer
钯催化荧光二聚体的环化,其中强效雌激素雌二醇的两个核心通过 1,4-二乙炔基苯部分桥接,产生带有 1,4-二(苯并呋喃-2-基)苯的类固醇二聚体。所得化合物显示出强烈的蓝色荧光,其特征在于350至550 nm之间的宽发射带,在384、403、435和456 nm处有四个最大值。与合成前体相比,苯并呋喃二聚体的量子产率提高了 18 倍。
