The recognition of nitroaromatic explosives by a tetrakis-tetrathiafulvalene-calix[4]pyrrole receptor (TTF-C[4]P) yields a “turn on” and fingerprinting response in the resonance Raman scattering observed in solution and the solid state. Intensity changes in nitro vibrations with analyte complexation occur via a mechanism of resonance between the 785 nm laser line and the strongly absorbing charge-transfer chromophore arising from the complex between electron-donating TTF-C[4]P and electron-accepting nitroaromatic explosives. The addition of chloride forms the Cl⁻·TTF-C[4]P complex resetting the system for reuse.

在溶液和固态中，主客体络合后，通过共振共振拉曼增强爆炸物的检测能力

四-四硫富瓦烯-杯[4]吡咯受体（TTF-C [4] P）识别硝基芳族炸药会在溶液和固态共振拉曼散射中产生“开启”和指纹识别响应。伴随着分析物络合的硝基振动强度变化是通过785 nm激光线与强吸收性电荷转移生色团之间的共振机制发生的，该电荷生色团是由供电子的TTF-C [4] P与受电子的硝基芳族炸药之间的络合物引起的。加入氯化物的形成氯^- ·TTF-C [4] P复合物复位以便重新使用该系统。
