Meso-tetra(4-sulfonatophenyl)porphyrin (TPPS) interacts with trinitrotoluene (TNT) and forms a 1:1 complex with a new absorbance peak at 422 nm. TNT quenches TPPS emission intensity at 645 and 702 nm when excited at 413 nm. The TPPS-TNT complex is formed in the ground state on the basis of a linear Stern-Volmer plot indicative of static quenching. The association constants determined from absorbance and fluorescence studies are in excellent agreement.
中-四(4-磺酸基苯基)卟啉(TPPS)与三硝基甲苯(TNT)相互作用，形成一种在422nm处有新吸收峰的1:1配合物。当在413nm激发时，TNT会猝灭TPPS在645和702nm处的发射强度。基于表明静态猝灭的线性斯特恩-沃尔默图，TPPS-TNT配合物在基态形成。通过吸光度和荧光研究确定的缔合常数非常吻合。
