Abstract

3-(4-Formylphenyl)-triazole-coumarin hybrid chromophores (FPhTCs) were synthesized in good yields, using a click chemistry protocol, and were also structurally characterized. Their photophysical, electrochemical and thermal properties were measured demonstrating that FPhTCs are luminescent in the blue-violet region of the electromagnetic spectrum, both in solution and the solid state. They showed an electrochemical band-gap values of 2.79 ± 0.08 eV, resistivity values between 10 and 10 Ω cm and are thermally stable up to 225 °C, properties that promise FPhTCs as good candidates for optoelectronic or imaging applications. Their solution and solid state photoluminescent properties are discussed and supported by theoretical calculations.

摘要

采用点击化学方法，以良好的产率合成了3-(4-甲酰基苯基)-三唑-香豆素杂化发色团（FPhTCs），并对其进行了结构表征。测定了它们的光物理、电化学和热性能，结果表明FPhTCs在电磁光谱的蓝紫色区域均有发光，无论是在溶液中还是固态下。它们的电化学带隙值为2.79±0.08 eV，电阻率值在10至10Ω·cm之间，热稳定性高达225℃，这些特性表明FPhTCs有望成为光电子或成像应用的良好候选材料。文中讨论了它们在溶液和固态下的光致发光特性，并通过理论计算进行了支持。
