摘要
两个基于苯并噻唑的吡唑啉衍生物3a和3b被合成,化合物3a的结构通过晶体衍射得到证实。紫外和荧光光谱检测了3a和3b在不同的溶剂中的的光学性质,结果显示,在不同溶剂和相同的条件下,由于共轭体系的增长,化合物3b的最大吸收和最大发射波长与3a相比发生明显红移,其荧光强度也明显增强,具有更好的发光性能。
Two benzothiazolyl pyrazolines(3a and 3b have been synthesized and the structure of 3a was confirmed by single crystal X-ray diffraction.Their photophysical properties were studied by absorption and fluorescence spectra.The result showed that the absorption and emission wavelength of compound 3b has obvious red-shift than that of compound 3a because of the increase of conjugated system in different solution at the same condition.Compound 3b has stronger fluorescence than compound 3a.
