Abstract

New complexes with the DAFO (4,5-diazafluoren-9-one) ligand of stoichiometry [Ag(DAFO)(P-P)]OTf [P-P = dppe, 1,2-bis(diphenylphosphane)ethane; dppp, 1,3-bis(diphenylphosphane)propane; dppph, ortho-bis(diphenylphosphane)benzene; dppcc, 1,2-bis(diphenylphosphane)-1,2-dicarba-closo-dodecaborane; dipcc, 1,2-bis(diisopropylphosphane)-1,2-dicarba-nido-dodecaborane], [Ag(DAFO)(P-P*)] [P-P* = dppnc, 7,8-bis(diphenylphosphane)-7,8-dicarba-nido-undecaborate(-1); dipnc, 7,8-bis(diisopropylphosphane)-7,8-dicarba-closo-undecaborate(-1)] and [Ag(DAFO)(OTf)L] [L = PPh3; dpccMe, 1-diphenylphosphane-2-methyl-1,2-dicarba-closo-dodecaborane] are reported. The structures of the complexes depend on the skeleton of the diphosphane. Most of these compounds are luminescent and their emissions seem to have originated from IL (DAFO) transitions, modified upon coordination to silver.

摘要

报道了化学计量比为[Ag(DAFO)(P-P)]OTf [P-P = 二(二苯基膦基)乙烷（dppe）、1,3-二(二苯基膦基)丙烷（dppp）、邻二(二苯基膦基)苯（dppph）、1,2-二(二苯基膦基)-1,2-二碳代-闭式-十二硼烷（dppcc）、1,2-二(二异丙基膦基)-1,2-二碳代-巢式-十二硼烷（dipcc）]、[Ag(DAFO)(P-P*)] [P-P* = 7,8-二(二苯基膦基)-7,8-二碳代-巢式-十一硼酸盐（-1）（dppnc）、7,8-二(二异丙基膦基)-7,8-二碳代-闭式-十一硼酸盐（-1）（dipnc）]以及[Ag(DAFO)(OTf)L] [L = 三苯基膦（PPh3）、1-二苯基膦基-2-甲基-1,2-二碳代-闭式-十二硼烷（dpccMe）]的新型配合物。配合物的结构取决于二膦的骨架。这些化合物大多具有发光性，其发射似乎源于IL（DAFO）跃迁，在与银配位后发生了改变。
