摘要
研究了在含有正丁醇(n-Bu)的猓泛ㄢ-CD)溶液中,加入有机小分子苯酚(phenol)后诱导1-溴代萘(1-BrN)发射强的室温光(RTP)的光谱性质。实验表明所研究体系中形成了1-BrN/猓瑿D/n-Bu/phenol四元包络物。考察了利用该体系测定痕量1-BrN的定量方法的可行性,结果发现1-BrN的线性范围为:1.0×10―5―1.0×10-4mol/L,其检出限为6.02×10-9mol/L。
Intense room temperature phosphorescence (RTP) o f 1-bromonaphthalene (1-BrN) induced by phenol and 1-butanol (n-Bu) was studied in aqueous It has been found that co nsiderably enhanced RTP arises from the formation of the 1-BrN/ u/phenol quadri-inclusion complex, and the phenol and n-Bu are incorporate d into the cavity of Th e temperature and the amount of phenol, n-Bu and ensity of RTP. The detection limit for 1-BrN in the range of 1.0- 5-1.0×10-4mol/L is 6.02×10-9 mol/L.
