“…Furthermore, the aromatic C-H bending vibration and Fe-Cp stretching vibration appear at 802 and 492 cm À1 , respectively. The FTIR spectrum shows the characteristic peaks of a ferrocene-based polyester and the spectrum coincides with the literature [2,[37][38][39][40][41][42][43].…”

Poly(diethyleneglycol 1,1′-ferrocene dicarboxylate) (PDEFD) was synthesized by solution polycondensation reaction of diethylene glycol with 1,1′-ferrocenyl chloride. The synthesized polymer was characterized via the measurement of its 1 H NMR spectrum, UV-vis spectrum, and FTIR spectrum. X-ray diffraction pattern was measured to investigate the crystallinity of the synthesized polymer and it was found that the polymer was mostly amorphous. The molecular weight of the polymer was determined by gel permeation chromatography. In addition, the electrochemical properties of the synthesized polymer were examined and the influence of many parameters, including the solvent, the scan rate, and the electrolyte concentration was studied. The electrode processes were found to be controlled by both electrode reaction and the mass diffusion. In addition, the electrochemical processes of PDEFD in dimethyl sulfoxide (DMSO) were confirmed neither to be totally reversible nor completely irreversible. Moreover, the thermogravimetric analysis and differential thermal analysis were employed to examine the thermal properties of the polymer. Finally, the liquid crystalline properties of the synthesized polymer were investigated via the polarizing optical microscope technique.

The anticancer effect of photodynamic therapy (PDT) is usually impeded by the hypoxia microenvironment in solid tumors; thus, it requires integration with other treatment tactics to achieve an optimal anticancer efficacy. Porphyrin-containing nanotherapeutic agents are broadly used for PDT in tumor treatment. However, chemodynamic therapy (CDT) of porphyrin-based namomaterials has been rarely reported. Here, a novel nanoscale porphyrincontaining covalent organic polymer (PCOP) was designed by the cross-linking of 5,10,15,20-tetrakis(4-aminophenyl)porphyrin with 1,1′-ferrocenedicarboxylic acid at room temperature. After glucose oxidase (GOx) was loaded, the obtained nanotherapeutic agent of PCOPs@GOx presented an augmented synergy of PDT, CDT, and energy starvation to suppress tumor growth upon near-infrared light irradiation. In vitro and in vivo outcomes demonstrated that this multifunctional nanoplatform not only realized excellent tumor inhibition but also provided a new tactic for designing chemodynamic/photodynamic/starvation combined therapy in one material.

Ferrocene‐based polymers are characterized by their electrochemical activity, good redox properties, thermal, photochemical stability, and liquid crystallinity, and thus they have various applications in different fields. A comprehensive investigation on the synthesis and properties of three novel main‐chain ferrocene‐based polyesters with azobenzene in the side chain (MFPAS) was carried out. The main‐chain ferrocene‐based polyester, poly(N‐phenyldiethanolamine 1,1′‐ferrocene dicarboxylate (PPFD), was synthesized via the solution polycondensation reaction of 1,1′‐ferrocenedicarbonyl chloride with phenyldiethanolamine (PDE). The novel MFPAS were synthesized via the post‐polymerization azo‐coupling reaction of PPFD with three different 4‐substituted anilines including 4‐nitroaniline, 4‐aminobenzoic acid, and 4‐aminobenzonitrile to produce 4‐nitrophenylazo‐functionalized‐PPFD (PPFD‐NT), 4‐carboxyphenylazo‐functionalized‐PPFD (PPFD‐CA), and 4‐cyanophenylazo‐functionalized‐PPFD (PPFD‐CN), respectively. All the synthesized polymers were characterized by 1H NMR spectroscopy, Fourier transform infrared spectroscopy, and UV–visible spectroscopy. In addition, powder X‐ray diffraction patterns were measured for the synthesized polymers. The photoisomerization of the MFPAS was studied. The thermal properties of the MFPAS were studied using thermogravimetric analysis and differential scanning calorimetry. PPFD‐CA and PPFD‐CN were found to be more thermally stable than PPFD‐NT. Finally, the liquid‐crystalline properties of PPFD and the MFPAS were examined using polarized optical microscope. It was found that all the polymers possessed nematic phases and exhibited textures with schlieren disclinations. Copyright © 2012 John Wiley & Sons, Ltd.
