Abstract:
Here, we prepared the first series of 3D hybrid iodoplumbates with novel porous frameworks of [Pb8I21]5- directed by transition metal complex (TMC) cationic dyes of [TM(2.2-bipy)3]2+. The microporous materials exhibit outstanding visible light-driven photoelectric properties due to the effective photosensitization of the TMC dyes. The coexistence of stronger face- and weaker corner-shared connecting manners affords the feasibility of tailoring the 3D framework into low-dimensional skeletons, which provide a new structural prototype to modify the semiconducting properties similar to those of classic perovskites.

Crystal Field Theory - Octahedral Complexes
To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals.
CFT focuses on...
Metal-Ligand Bonds
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...

Structure and Physical Properties of Alkynes
In nature, compounds containing both carbon and hydrogen are known as "hydrocarbons". Aliphatic hydrocarbons are compounds whose molecules contain saturated single bonds (i.e., alkanes) or unsaturated double or triple bonds. Alkenes contain carbon–carbon double bonds and have a structural formula CnH2n. Unsaturated hydrocarbons containing carbon–carbon triple bonds are called "alkynes" and are structurally represented by the formula CnH2n-2.
