对甲基苯硫酚功能化的螺-9,9'-氧杂蒽芴的设计合成及其光电性质
Design,synthesis and photoelectric properties of the p-methylthiophenol functionalized spiro-9,9'-oxanthrene fluorene
摘要
Abstract
A novel spiro compound 2,7-di(4-methylthiophenol)-spiro-9,9'-oxanthrene fluorene(DMePhS-SFX)was successfully prepared by functionalizing spiro-9,9'-oxanthrene fluorene(SFX)with p-methylthiophenol using cuprous oxide as a catalyst.The molecular structure was detailedly characterized by high resolution mass spectrometry,hydrogen spectroscopy and carbon spectroscopy.The data of thermogravimetric analysis showed that the thermal decomposition temperature of DMePhS-SFX was as high as 375 oC with 5%weight loss.The UV absorption and fluorescence spectra showed that the compound had intense absorption ranging from 220 to 370 nm,and the wavelength of its maximum emission peak was around 379 nm.The triplet energy level of the compound was 2.51 eV that was calculated from the first emission peak of phosphoresce luminescence at low temperature,which indicated that the compound could be used as host material to prepare red and green phosphorescent devices.The highest occupied orbit(HOMO)and the lowest unoccupied orbit(LUMO)energy levels were-5.88 eV and-2.16 eV,respectively,which were obtained by cyclic voltammetry.关键词
