effectively to give 1h. Spectroscopic properties of these compounds were recorded, and correlations between substituent effects, UV absorbance, fluorescence emissions, and quantum yields were made. Compound 1a was coupled with a fluorescein-alkyne derivative to give the energy transfer cassettes 2 and 3. Both these compounds gave poor energy transfer, and the possible reasons for this were discussed.
发射近红外线的荧光分子有可能用作生物技术的探针。这种类型的探针的一个相对未充分探索的设计是 aza-BODIPY 染料;进行这项研究是为了加深我们对这些材料以及它们在染料盒系统中的使用方式的理解。因此,制备了氮杂-BODIPY染料1a-g。制备了该系列中第八个化合物 6h 的高级中间体,但它不能与硼有效络合以产生 1h。记录了这些化合物的光谱特性,并建立了取代基效应、紫外吸收、荧光发射和量子产率之间的相关性。化合物 1a 与荧光素-炔衍生物偶联得到能量转移盒 2 和 3。这两种化合物的能量转移都很差,
