“…Micron sized belt‐like COP was prepared in the absence of Fe 3+ (Figure S1 a and S1 b). Attributed to the strong coordination and chelating effect of Fe 3+ , a nano‐sized Fe‐Pa complex was produced by introduction of Fe 3+ (Figure S1 c and S1 d). Finally, monodispersed spherical MCOP with sizes around 120 nm were obtained due to the template effect of nanoscale Fe‐Pa complex, and the optimal amount of Fe and Gd was determined to be 0.03 mL of FeCl 3 (0.308 m ) and 0.01 mL Gd(NO 3 ) 3 ⋅6 H 2 O (0.1108 m ), respectively (Figure 1 a– b and Figures S2–S4).…”

Size- and shape-controlled growth of nanoscale microporous organic polymers (MOPs) is a big challenge scientists are confronted with; meanwhile, rendering these materials for in vivo biomedical applications is still scarce. In this study, a monodispersed nanometalated covalent organic polymer (MCOP, M=Fe, Gd) with sizes around 120 nm was prepared by a self-templated two-step solution-phase synthesis method. The metal ions (Fe , Gd ) played important roles in generating a small particle size and in the functionalization of the products during the reaction with p-phenylenediamine (Pa). The resultant Fe-Pa complex was used as a template for the subsequent formation of MCOP following the Schiff base reaction with 1,3,5-triformylphloroglucinol (Tp). A high tumor suppression efficiency for this Pa-based COP is reported for the first time. This study demonstrates the potential use of MCOP as a photothermal agent for photothermal therapy (PTT) and also provides an alternative route to fabricate nano-sized MCOPs.

“…It can be seen that the intensity of 2D band of the nanocomposites increase as the ratio of polymer increases in the composite which further confirms the occurrence of the both POA and GR in the composites. These bands are assigned to the π-π* transition centred on the benzenoid rings (interband transition) [53]. The observed peak at 613 nm is because of n-π* transition from the non-bonding nitrogen lone pair to the conduction band (π*).…”

“…On the other hand, these frameworks can be coupled with oxomolybdates and can form semiconductor nanostructures [22] with novel applications in photoluminescence [23,24], light harvesting [25,26] and so on. PPDA as multifunctional organic ligand can be placed between structural blocks of oxomolybdates which are widely used in the structure of inorganic-organic nanohybrids as agents for structural directing to facilitate the formation of different networks [27]. These ligands can not only be used as coordination factors to transition metals, but also cause the formation of one-dimensional or multi-dimensional networks by forming intermolecular interactions, such as hydrogen bonding [28][29][30][31].…”

The new nanocrystalline composition was synthesized using NiSO 4 and MoO 3 and PPDA (p-phenylenediamine) via the hydrothermal method. The structure, morphology and photoluminescence property of nanocrystal were studied using X-ray diffraction (XRD), Fourier transform infra red (FT-IR) spectroscopy, scanning electron microscopy (SEM), photoluminescence (PL) spectra, thermogravimetric analysis (TGA-DTA) and energy-dispersive X-ray spectroscopy (EDX). The effect of factors such as type and concentration of initial materials, pH values, temperature and reaction duration on the structure and morphology of nanocrystals was investigated in the preparation of composition. The results show that the pH of the initial solution affects the size of the prepared nanocrystals; the size of the crystals is increased and the morphology of the nanostructures is changed with the increment in pH value. According to the obtained results, neutral or low alkaline conditions of pH are more favorable for the formation of the nanocrystals. The obtained nanocrystal shows an intense PL emission at room temperature with a maximum peak at 461 nm and excitation at the wavelength of 300 nm. TGA and DTA analysis display a total weight loss of 13.42%.
