资源简介：
The photophysical properties of the series of quadruply bonded M2(O2C−Ar)4 [M = Mo, Ar =
phenyl (ph), 1-naphthalene (1-nap), 2-naphthalene (2-nap), 9-anthracene (9-an), 1-pyrene (1-py), and
2-pyrene (2-py); M = W, Ar = ph, 2-nap] complexes were investigated. The lowest energy absorption of
the complexes is attributed to a metal-to-ligand charge transfer 1MLCT transition from the metal-based δ
HOMO to the π* O2C−Ar LUMO. The Mo2(O2C−Ar)4 complexes exhibit weak short-lived emission (
本研究对一系列四重键合的M2(O2C−Ar)4 [M = Mo, Ar = 苯基（ph）、1-萘（1-nap）、2-萘（2-nap）、9-蒽（9-an）、1-芘（1-py）和2-芘（2-py）；M = W, Ar = 苯基（ph）、2-nap]配合物的光物理性质进行了探究。这些配合物的最低能量吸收归因于从金属基态反键轨道（δ HOMO）到π* O2C−Ar反键轨道（LUMO）的金属至配体电荷转移（1MLCT）跃迁。Mo2(O2C−Ar)4配合物表现出微弱而短暂的发射（
