Three different networks have been synthesized using 4-vinylpyridine and divinylbenzene (0.5, 1.0, and 2.0 mol %, respectively) and are further complexed with pentadecylphenol or nonadecylphenol. For low degrees of cross-linking (0.5 and 1.0 mol % divinylbenzene), mesomorphic structures are formed, and order-disorder transitions are observed by small-angle X-ray scattering (SAXS) and differential scanning calorimetry. For the highest degree of cross-linking (2.0 mol % divinylbenzene), mesomorphic structures is no longer observed. The presence of ordered lamellar structures is confirmed by transmission electron microscopy (TEM). SAXS and TEM clearly reveal the deteriorating effect of an increasing degree of cross-linking on the structure formation.

Self-Assembled Poly(4-vinylpyridine)−Surfactant Systems Using Alkyl and Alkoxy Phenylazophenols

“…Such a structure is well-known from many other (covalent and noncovalent) side-chain polymer systems, 34,39,52 including P4VP(PDP). 51 A striking difference between the nPAP amphiphiles on the one hand and pentadecylphenol on the other is the strong increase in periodicity going from the crystalline state of pure PDP to the smectic P4VP(PDP) complex, respectively 2.6 and 3.7 nm ( Table 2). For PDP this difference is about 1.1 nm, whereas for the PAP amphiphiles it varies from 0.2 to 0.4 nm only.…”

Complexation between hydrogensulfated fullerenol and poly(4-vinylpyridine)

“…P4VPy can also form interpolymer complexes with acidic polymers such as poly(monomethyl itaconate) 26) , poly(ethylene-comethacrylic acid) 27) , poly(2-acrylamido-2-methylpropanesulfonic acid) 28) and poly(p-vinylphenol) 29) . Supramolecular materials based on complexes of P4VPy and amphiphiles were also reported recently 30,31) . A recent paper on the synthesis of hydrogensulfated fullerenol (HSF) with multiple 1OSO 3 H groups has led us to prepare HSF/ A fullerene (C 60 ) derivative, hydrogensulfated fullerenol, has been complexed with poly(4-vinylpyridine) (P4VPy) through a supramolecular approach.…”

Preparation of fluorescent DNA probe by solid-phase organic synthesis

“…FT-IR spectra of PDVB microspheres (Figure 2 a) shows a peak at 2923 cm -1 attributed to the asymmetrical stretching of methylene groups while the band at 1603 cm -1 originated from the asymmetrical stretching of conjugated double bonds [21]. The increase of 1415 cm -1 absorptions was caused by the introduction of pyridine ring [24] (Figure 2b) of PDVB@PVPy microspheres, and the loading capacity of the pyridyl group on the polymer microspheres was 0.134 mmol/g.…”
