Abstract In this study, five new paraben substituted cyclotriphosphazene compounds containing hydrophilic glycol groups were successfully synthesized. All synthesized cyclotriphosphazene compounds 1-10 were fully characterized via general spectroscopic techniques such as 1H, 31P NMR and MALDI-TOF mass spectrometry. In addition, the investigations of the UV-vis absorption and fluorescence emission properties of the 1-10 carried out via absorption and fluorescence spectroscopies in different solvents. The absorbance bands of the all synthesized compounds 1-10 were observed at about 230–300 nm in all solvents studied. Furthermore, the highest fluorescence emission intensity of the compounds 1-10 was observed in tetrahydrofuran at about 312 nm and the lowest emission intensity was observed in chloroform. The synthesized molecules can be used as custom designed molecules to investigate the DNA binding properties in automatic biosensor device in our laboratories, since they carry hydrophilic glycol units for water solubility and paraben derivatives for DNA effecting properties.

具有亲水侧基的对羟基苯甲酸酯取代环三磷腈的合成、表征和光物理性质

摘要 本研究成功合成了五种含有亲水性二醇基团的对羟基苯甲酸酯取代的环三磷腈化合物。所有合成的环三磷腈化合物 1-10 都通过一般光谱技术（如 1H、31P NMR 和 MALDI-TOF 质谱法）进行了充分表征。此外，通过在不同溶剂中的吸收和荧光光谱对 1-10 的紫外-可见吸收和荧光发射特性进行了研究。在所研究的所有溶剂中，在约 230-300 nm 处观察到所有合成化合物 1-10 的吸收带。此外，化合物 1-10 在四氢呋喃中的最高荧光发射强度在约 312 nm 处观察到，而在氯仿中观察到的发射强度最低。合成的分子可用作定制设计的分子，以研究我们实验室自动生物传感器装置中的 DNA 结合特性，因为它们携带亲水性乙二醇单元用于水溶性和对羟基苯甲酸酯衍生物用于 DNA 影响特性。图形概要
