nndnp和NMA的准分子发射在多电解质（NaPSS）存在的水溶液中显著增强。这种增强归因于探针与微阴离子的关联（由于亲水性，静电性和疏水性相互作用）。在8 × 10”5 M NaPSS的作用下，NMA的分子间准分子形成速率常数k′提高了103。nndnp的分子内和分子间准分子形成都发生在水溶液中NaPSS的存在下。NaCl和Co (NH3) 5C13抑制了nndnp准分子的形成，而高压增加了nndnp准分子的发射强度和寿命。我们感谢美国国家科学基金会对这项工作的慷慨支持。我们也感谢H. Morawetz教授就他以前的相关调查和解释提供了翔实和有益的意见。
The excimer emissions of NDNP and NMA are dramatically enhanced in the presence of polyelectrolyte (NaPSS) in aqueous solution. This enhancement is attributed to the association (due to hydrophilic, electrostatic, and hydrophobic interactions) of the probes with microanions. The intermolecular excimer formation rate constant, k¡, of NMA is enhanced by 103 in the presence of 8 X 10" 5 M NaPSS. Both intramolecular and intermolecular excimer formation of NDNP occur in the presence of NaPSS in aqueous solution. NaCl and Co (NH3) 5C13 retard excimer formation, while high pressureincreases both the emission intensity and the lifetime of the excimer of NDNP.Acknowledgment. We thank the National Science Foundation for its generous support of this work. We also thank Professor H. Morawetz for informative and helpful comments concerning his previousrelated investigations and interpretations.
