摘要： 萘氧乙酸(NOA)是一类植物生长调节剂.对NOA在β-环糊精(β-CD)保护下的室温磷光(RTP)性质[1]和荧光性质[2]研究已有报道,但无保护性介质存在下的RTP性质研究尚未见报道.

Abstract: A strong and stableroom tempera ture phospho rescence(RTP)signal of α-naph-thalenyloxyacetic acid(α-NOA)aqueous solution can be induced on ly by using Na2SO3 as de-oxidizer and KI(or TlNO3)as heavy a tomperturber. The maximum phospho rescence in ten-sity wavelengths a reλexλem=287/495, 521nm(orλexλem=297/494,521nm)when KI(or TlNO3)a s heavy a tomperturber. Though the RTP signal is lower with KI as heavy a tomperturber than that with TlNO3,but the analy tical cha racteristics of the former is better than that of the latter. The kind and amount of organic solvent added to the system have a strong effect on the RTP intensity,irradiating time required to acquire stable RTP signal and the choice of heavy a tomperturber.

Key words: α-Naphthalenyloxyacetic acid, Non-protected room temperature phosphores-cence, Effect of organic solvent, Choice of heavy atom perturber
