“…Mohammadikish and co-workers [ 136 ] synthesized a bi-metallic CP with a Schiff base ligand resulting from the condensation of a functionalized aldehyde and p-aminobenzoic acid, coded Zn-Mo-ICP ( 81 ) (ICP = infinite coordination polymer). The complex has proven its ability to adsorb MB (100%) and MO (52%), suggesting the tendency to more efficiently adsorb cationic dyes (MB).…”

This review considers the applications of Zn(II) carboxylate-based coordination polymers (Zn-CBCPs), such as sensors, catalysts, species with potential in infections and cancers treatment, as well as storage and drug-carrier materials. The nature of organic luminophores, especially both the rigid carboxylate and the ancillary N-donor bridging ligand, together with the alignment in Zn-CBCPs and their intermolecular interaction modulate the luminescence properties and allow the sensing of a variety of inorganic and organic pollutants. The ability of Zn(II) to act as a good Lewis acid allowed the involvement of Zn-CBCPs either in dye elimination from wastewater through photocatalysis or in pathogenic microorganism or tumor inhibition. In addition, the pores developed inside of the network provided the possibility for some species to store gaseous or liquid molecules, as well as to deliver some drugs for improved treatment.

“…The presence of two adjacent vibrational bands at 907 and 948 cm À 1 related to stretching vibrations of Mo=O in Cis-MoO 2 species approves the successful formation of molybdenum Schiff-base complex inside the SBA-16 nanocages through ship-in-a-bottle method. [23] Moreover, the stretching vibration of PÀ C bond in Schiff-base ligand can be seen at 716 cm À 1 . Also, the observed stretching and bending vibrations of methylene groups (2947 and 1440 cm À 1 , respectively) are related to incorporated trimethoxyoctylsilane species on SBA-16 surface.…”

A new heterogeneous catalyst with a unique design was successfully synthesized through a ship‐in‐a‐bottle strategy to incorporate a highly active molybdenum Schiff‐base complex within the nanocages of SBA‐16 for epoxidation reaction. For this aim, all the chemical precursors for preparation of this complex were mixed step by step in the presence of SBA‐16 and the entry of nanocages were finally tuned via silylation with long chain trimethoxyoctylsilane reagent in order to avoid the possible release of encapsulated complex. The final catalyst (named as PPh3‐Sal/Mo@SBA‐16) was characterized by FT‐IR and UV‐Vis spectroscopies, nitrogen adsorption‐desorption and X‐ray diffraction (XRD) analyses as well as scanning and transmission electron microscopies (SEM and TEM). All of these physicochemical techniques approved the incorporation of molybdenum Schiff‐base complex inside the SBA‐16 nanocages and maintenance of physical properties of SBA‐16 after encapsulation process. As predicted, epoxidation of some allylic alcohols and alkenes were proceeded selectively toward desired epoxides with high efficiency beyond 80 % over PPh3‐Sal/Mo@SBA‐16 catalyst. Eventually, the reusability experiment revealed the catalyst stability after five successive epoxidation reaction with only minor reduction of overall efficiency.

“…This problem leads to delays to custom epoxidized vegetable oils as suitable alternatives to conventional petroleum-based epoxy. [11,12]. Therefore, the formation of cyclic ether at sites of a double bond of unsaturation of fatty acid or oil (C=C) and the addition of a peracids compound to get a three-member cyclic ring indicates the epoxidation reaction of vegetable oil in the formation of either oxirane ring [13] or oxirane cleavage [14].…”
