A new series of coordination polymers, namely, CP2 [{(H2O)Co1.5(μ-3-bpna)1.5(μ-btc)}·3DMF·3H2O]α, CP3 [{Cd(μ-3-bpna)(μ-hbtc)}·CH3OH·2H2O]α, CP4 [{Co(μ-3-bpna)(μ-ipa)}·DMF·2H2O]α, CP5 [{Co(μ-3-bpna)(μ-1,3-pda)}·DMF]α, CP6 [Cd(μ-3-bpna)0.5(μ-1,3-pda)]α, CP7 [(H2O)Co0.5(μ-3-bpna)0.5(μ-1,4-pda)0.5]α, and CP8 [{Zn(μ-3-bpna)(μ-oba)}·DMF·2H2O]α, has been synthesized by reacting a hydrogen-bond-functionalized bis-pyridyl ligand, namely, N′,N″-di(pyridin-3-yl)naphthalene-2,6-dicarboxamide, with various transition metal salts and different di- or tricarboxylates (as co-ligand) displaying 2D and 3D network topology and having lattice-occluded solvents in the majority of cases. A 1D coordination polymer, namely, CP1 [{Ag0.5(μ-3-bpna)}0.5·0.5BF4·CH3CN]α, has also been isolated by reacting 3-bpna with AgBF4 in the absence of any carboxylate co-ligand. All of the CPs were characterized by single crystal X-ray diffraction. Interestingly, two such CPs, namely, CP1 and CP2, produced metallogels, which were characterized by rheology, transmission electron microscopy, and X-ray powder diffraction. The metallogel of CP1 produced Ag nanoparticles within the gel bed upon exposure to light. (Chemical Equation Presented).

Paragraph 0040; 0041; 0042, (2017/08/25)
The invention discloses functional diamine monomers having high planarity and containing a naphthaline structure and a synthesis method and application thereof. The novel functional diamine monomers are prepared from raw materials monomers such as dihalogenated naphthaline, naphthalic acid, naphthalenediol or naphthylenediamine through a series of chemical reactions such as substitution reaction, Suzuki reaction, amidation reaction, esterification reaction, Grignard reaction, Kumada coupling reaction. The diamine monomers containing a naphthaline structure, which have a lowest energy state 3D molecular structure and have high planarity, can be obtained. Due to planar space structure, the diamine monomers disclosed by the invention can serve as monomers used for preparing polymers with strong molecular chain interaction force, tight molecular chain packing and small free volume and the polymers can be endowed with an excellent barrier property. The synthesis method of the diamine monomers is simple in process and purification operation is easy; therefore, the synthesis method is suitable for industrial production. The diamine monomers disclosed by the invention can be used for synthesizing functional polymers such as polyamide, polyimide, polyamide-imide and polyester-imide.
