Abstract:
By introducing an electro-withdrawing antipyrine group, N-(p-toluenesulfonyl)-N-(4-antipyrine)-10-methylacridinium-9-carboxamide triflate was prepared. The UV, FL and CL properties of the target compound and of its precursor were investigated by comparing with those of the model compound N-(p-toluenesulfonyl)-N-phenyl-10-methylacridinium-9-carboxamide triflate and the corresponding precursor respectively. The results show that acridine sulfonamide with a heterocyclic antipyrine group exhibits blue shift of both UV absorption and of maximum excitation wavelength(λex) and emission wavelength(λem) in FL spectra, comparing with the corresponding model compound. The λex of the final target and its precursor are 268 and 274 nm, respectively; and the λem are 321 and 327 nm, respectively, while λex of the model compound and its unmethylated precursor are 365 and 359 nm, respectively; and the λem are 504 and 440 nm, respectively. Moreover, the chemiluminescence of the final target compound triggered by H2O2 could finish within 1.1 s; and the quantum yield is similar to that of the model compound, being 5.6 times high as that of luminol.
