In this research, 18 compounds were synthesized by employing organic amine as template under hydrothermal conditions. They were classified into three systems: System A put emphasis on reduction of energy consumption and chemical recycling of waste PET. Reactions with the use of microwave as an energy source largely cut down the reaction time to 1% as compared to conventional heating time and successfully yielded three single-phased products of A1, A2 and A3. The compounds A2,A3 and A5 displayed 3D structures “seemingly the same “ but they are not exactly identical due to the common organic linkers of BDC moiety adopting different orientations with respect to the same inorganic framework. The results should overturn our conventional cognition on scaling up product by microwave synthesis. On the other hand, scraps of waste PET bottle were successfully employed in two reactions as potent reagents to produce new compound A5 and high-valued phosphor materials A6 with potential application to white-light LEDs, providing a brand new perspective to chemical recovery of waste PET. System B contains six layered zinc phosphates encapsulating organic supra molecules as guest species. Bearing intricate hydrogen-bonding patterns within each layer, the pseudo-neutral (H3tren)2[Zn3(PO4)4] sheets are highly adaptable to varied achiral organic monomers, making them transformed into different chiral supramolecular chains. As a result, the entire structures of B1-B4 were turned into chiral as well. Depending on the molecular size of guest monomers, the layer gap was able to pop up the most to 2.01 nm (B4). Furthermore, the zinc center could be doped with homo-valence transition metal ions. Incorporation of Co2+ ions into layers exerted strong influence on supramolecular guests’ arrangements while doping of Mn2+ ions created novel photoluminescence property-the inter-layer supramolecular guest became a good sensitizer for the emission of bright orange- (from B1-Mn) or pink- (from B4-Mn) light under UV excitation. System C involved the use of bola-type surfactant, the long chain amine-DADD, as organic template. In the synthesis additional bulky organic acid-BPDA was included together with (metal) phosphate to generate six layered materials. The compound of C3 is highly interesting as it not only was observed ultra-large inter layer gap of 2.2nm but also revealed intriguing green afterglow property. In the three systems, every structure was well-characterized and extended to the discussion on their syntheses, thermal properties, self-assembly of supramolecular guests and the mechanisms of luminescence. The study generated significant results with substantial novelty and made conceptual breakthroughs to the field of organic/inorganic hybrid metal phosphate materials.

Two series of metal phosphate and phosphites structural, A and B, were shown as follows:(DA1)Zn2(Lcis)(HPO4)2 (A1)、(DA1)Zn2(Ltrans)(HPO4)2 (A2)、Zn3(L)0.5(DA2)(HDA2)(HPO3)2 (B1) and Co3(L)0.5(DA2)(HDA2)(HPO3)2 (B2). A1 and A2 were synthesized with the same reactants under the mild hydrothermal conditions. B1 and B2 had a similar structure with different metal center (B1 for Zn and B2 for Co). All of these structures were determined by single-crystal X-ray diffraction. Purity determined by PXRD, EA, XRF and EDX. A1 and A2 are similar structure. BDC(L) bonded to Zn center with two different phases (cis and trans coordinate with metal). This is the first time we find in OMPO (organic-metallophosphate). By soaking A1 and A2 in Na+ solution, we found that DA1 were partially replaced by Na+ ion and ethanol. By the results of Element Analysis、Thermogravimetry Analysis and FTIR, we determined the new structure :(DA1)0.5Na(C2H5OH)0.5Zn2(L)(HPO4)2. A1 and A2 had no luminescence properties. However, by soaking Eu3+ and Tb3+ ions solution, A1-Eu/Tb and A2-Eu/Tb had luminescence properties (green light for A1/A2-Tb and red light for A1/A2-Eu). Soaking in Cu(NO3)2, powder color of B1 would turn white to blue by exchanging Cu ion for only an hour. B1 was also a good sensor for Cu2+ ion. The metal center of B2 was Co, which showed good magnetism. Determined by SQUID, B2 has paramagnetism in high temperature and antiferromagnetism in low temperature.

Nine new coordination polymers, [Mg2(BTEC)(H2O)4]·2H2O (1)、 Mg2(BTEC)(H2O)6] (2) 、[Mg2(BTEC)(H2O)8] (3) 、 (H2tmdp)[Zn2(HPO4)2(BDC)] (4) 、 (H2tmdp)[CoxZn2-x(HPO4)2(BDC)] (x~0.6) (5) 、(H2tmdpp)[Zn2(HPO4)2(BDC)] (6) 、 (H2tmdpp)[CoyZn2-y(HPO4)2(BDC)] (y~0.8) (7) (BTEC = 1,2,4,5-Benzenetetracarboxylic acid;BDC = 1,4-benzene dicarboxylate anion;tmdp = 4,4’-trimethylene dipyridine ; tmdpp = 4,4'-Trimethylene dipiperidine have been synthesized by microwave reactions. The crystalline solids of 1 to 3 were prepared from the microwave reactions of magnesium (II) nitrate with H4BTEC under optimized ratios and different pH value controlled at different basic conditions. The results of crystal structure analysis displayed that these products have multi-dimensional structures, that is, 3D for 1, 2D for 2, and 1D for 3. A series of new organo-metallophosphate hybrid frameworks compound 4 to 7 with carboxylate-linked frameworks have been successfully synthesised by microwave-assisted reactions. All compounds were successfully synthesized by only 40 minutes at 160 oC using a microwave oven, compared to three days by conventional Solvothermal reactions. The resultant phases of compounds 4、5 were found to transform to porous phases by heating at 250 oC under vacuum. For the first time, as we known, the organo-metallophosphate hybrid frameworks of compound 4 and 5 were found to transform to foamy phases by heating at 300 oC in air. In summary, the single crystal structure analysis, thermal studies, photoluminescence, and gas adsorption of compounds 1-7 have been fully characterized.
