generated carriers in TJU-18(Pb/Zn). This is further supported
by a smaller Nyquist plot diameter for TJU-18(Pb/Zn) than
those of the other three materials, measured by electro-
chemical impedance spectroscopy (Fig. 4a). Overall, the
improved photocatalytic performance of TJU-18(Pb/Zn) is
largely ascribed to the enhanced separation of the photogene-
rated electron–hole pairs and the enhanced photocarrier
transfer.
In conclusion, we successfully realized the atomically
precise control of introducing four different transition metal
centers (i.e. Mn2+, Co2+, Ni2+ and Zn2+) into an organolead oxy-
bromide crystalline framework, which are structurally eluci-
dated by X-ray crystallography. All of these semiconductive
materials are chemically stable in a variety of organic solvents.
Meanwhile, the photocatalytic properties of Zn2+-incorporated
bimetallic oxyhalide are superior to those of other bimetallic
members, probably owing to its enhanced carrier transport
mobility. We are further extending this synthetic strategy to
other lead halide materials, opening up an opportunity to
finely tune their photoactive properties by atomically precise
incorporation of transition metal centers.
