本文介绍了应用广泛的碱金属环戊二烯类化合物（CpLi, CpNa, CpK, CpRb, CpCs）在THF-d(S)溶液中的聚集基序。它们在THF-d(S)溶液中形成单体接触离子对（cip），而在NH3溶液中则形成溶剂分离离子对（SSIPs）。通过引入ECC-MW估计软件，进一步提高了ECC-DOSY的适用性。
In this paper we present the aggregational motifs of the widely used alkali-metal cyclopentadienides (CpLi, CpNa, CpK, CpRb, CpCs) in THF-d(S) solution estimated by ECC-DOSY NMR spectroscopy. They form monomeric contact ion pairs (CIPs) in THF-d(S) solution, whereas in NH3 solvent-separated ion pairs (SSIPs) are observed. The applicability of ECC-DOSY is further advanced by introducing ECC-MW estimation software.
