The luminescent complexes of triphenylphosphine and two interesting aminomethylphosphines: P(CH2N(CH2CH2)2NCH3)3 and P(CH2N(CH2CH2)2O)3 with copper(I) iodide and 2,9-dimethyl-1,10-phenanthroline (dmp): [CuI(dmp)PPh3], [CuI(dmp)P(CH2N(CH2CH2)2NCH3)3] and [CuI(phen)P(CH2N(CH2CH2)2O)3] are presented in this work. These complexes were characterized in solution by means of NMR spectroscopy and their structures
的发光配合物 三苯膦和两个有趣的氨基甲基膦:P(CH 2 N(CH 2 CH 2)2 NCH 3)3和P(CH 2 N(CH 2 CH 2)2 O)3与碘化铜(I)2,9-二甲基-1,10-菲咯啉(dmp):[CuI(dmp)PPh 3 ],[CuI(dmp)P(CH 2 N(CH 2 CH 2)2 NCH 3)3 ]和[CuI (phen)P(CH 2 N(CH 2 CH 2)2 O)3 ]出现在这项工作中。这些配合物在溶液中通过NMR光谱法表征,并且其结构在固态下通过晶体学确定。所有复合物均结晶为离散二聚体,这些二聚体受dmp环之间的π堆积相互作用所束缚。关于Cu(I)中心是伪四面体,显示较小的展平度和较大的摇摆变形。所研究的化合物表现出在固体状态下激烈橙光致发光(发射峰在rt:λ最大= 588-592纳米; τ = 1.7-2.2和6.4-10.0微秒;在77 K:λ最大= 605-612纳米;
