Phosphorus-containing smart, multifunctional polymers towards materials with dual stimuli responsivity, self-aggregation ability and tunable wettability

Multi-Stimuli Responsive Sequence Defined Multi-Arm Star Diblock Copolymers for Controlled Drug Release

“…To study the encapsulation capacity of the (PNIPAM-b-PMAA) 4 -UMB diblock copolymer nanocarrier, coumarin 102 (C102), a hydrophobic dye encapsulation, was studied using UV−vis spectroscopy. Results of this study revealed that the characteristic C102 absorbance (at 395 nm) 30,31 gradually decreased with time as shown in Figure 3a, leading to 42% encapsulation after 24 h incubation as shown in Figure 3c. The intensity of the fluorescence emission spectrum of C102 (Figure 3b) decreases after encapsulation compared with that of neat C102 solution, suggesting successful encapsulation of C102.…”

Comparative Study of Bis-Schiff Case Containing Conjugated Oligomers Based on Phosphate and Silane Moieties: Investigation of Photophysical and Thermal Properties

“…Despite their remarkable characteristics, aromatic poly(azomethine)s exhibit limited solubility in organic solvents and elevated melting temperatures, thereby constituting significant impediments for their viable industrial applications. Incorporating polar groups or flexible units like siloxane units into the conjugated aromatic azomethine frameworks presents an alternative way for enhancing their attributes. ,, Ester or ether linkage-containing poly(siloxane-azomethine)s have been appeared in the literature. − Furthermore, it is widely recognized that flame retardants incorporating silicon offer the distinct advantage of exceptional chemical stability and elevated resistance to high temperatures. , In addition, silicon- and phosphorus-incorporating flame retardants are recognized as environmentally benign flame retardant agents, offering an alternative choice for effectively augmenting the thermal stability of materials. − Due to the synergistic interaction between phosphorus and silicon elements, compounds incorporating phosphorus have been recognized as one of the potent flame retardants in many recent investigations. − Besides, the inclusion of phosphorus within the polymer matrix has the potential to enhance solubility and thermal stability. − …”

Fluorescent phosphine oxide-containing hyperbranched polyesters: design, synthesis and their application for Fe3+detection

“…In recent years, phosphorus-containing (P-containing) polymers have been widely studied as they exhibit very unique properties that make them useful in many fields, such as polymer electrolytes, 1 metal recovery, 2 fire-resistant materials 3 and biomaterials. 4 Phosphorus-containing polymers are prepared either via step-wise polycondensation (i.e., polyphosphoester 5 ) or chain polymerization (i.e., poly(vinyl phosphonic acid 6 )). Chain polymerization is always utilized in preparing side-chain phosphorus-containing polymers (where phosphorus is a pendant group), therefore the corresponding monomer design has attracted much attention.…”

“…Phosphorus-containing (meth)acrylate and (meth)acrylate monomers, for example, have been extensively studied and their corresponding polymers usually contain phosphonated esters, phosphonic acid or phosphoric ester functions. [6][7][8] In addition, there are other types of phosphoruscontaining monomers, such as phosphorus-containing vinyl 9 and styrenic 10 monomers. However, to date most of these unsaturated P-containing monomers have been derived from phosphorus trichloride (PCl 3 ), phosphorus pentachloride (PCl 5 ), and phosphorus oxychloride (POCl 3 ), with chlorine not present in the final monomers and the corresponding polymers.…”
