“…An interesting approach to hollow polymeric nanocapsules was detailed by Balasubramanian, Han and Chamberlayne. 197 The thiol-ene photopolymerisation of resorcinarene cavitand thiol with 2-, 3-or 4-functional enes yielded hollow nanocapsules of varying thickness and rigidity, the two latter features being controlled by the functionality of the ene, Fig. 35.…”

“…The shell thickness of these hollow nanospheres is, particularly in the context of applications, of great interest. For example, the thickness of the shells would allow control of properties such as permeability, degradation kinetics, rigidity, and mechanical strength (Balasubramanian et al 2013). Hence, more possibilities for different applications can be derived from their tunable properties.…”

This work discusses the preparation and characterization of hollow nanospheres based on kraft lignin (KL). Kraft lignin is a by-product of the papermaking industry and an abundant renewable resource. It was determined that adding water to a KL/THF solution induced KL to form hollow nanospheres via self-assembly. Scanning electron microscopy and transmission electron microscopy confirmed the hollow nanosphere morphology. The shell thickness of the hollow nanospheres was tunable by adjusting the initial KL concentration in THF, making the nanospheres a potential material for the encapsulation and controlled release of guest molecules. Ultraviolet (UV) and Fourier transform infrared (FTIR) spectroscopy confirmed the π-π stacking of aromatic rings as an important and distinctive mechanism for the formation of hollow KL nanospheres. The nanospheres were obtained simply and inexpensively, and they exhibited the characteristics of biocompatibility, biodegradability, and low toxicity. These advantages make hollow KL nanospheres attractive for applications in nanoscience and nanotechnology. This study developed an economically feasible and facile strategy for the effective use of biomass waste in sustainable chemistry.

“…Depending on the different parameters, including the concentration, solvent, temperature, and protocol of assembly, complex hierarchical morphologies are produced. Self‐assembly enables the use of polymers as efficient and site‐specific drug carriers because of their intrinsic properties of encapsulating a wide range of guest molecules; this can be controlled by various physical parameters . Because of its selective solubility profile in commonly used solvents and specific molecular interactions, porphyrin is challenging in the fabrication of controlled and well‐ordered nanostructures.…”

In this article, we detail the sonication‐induced self‐assembly of polymeric porphyrin and fullerenes into distinct nanorings in solution form. The formation of these trenchant superstructures was the result of the delicate choice of different assembly protocols, solvents, and polymeric tails associated with porphyrin and fullerene. In this study, the sonication supposedly directed the lateral aggregation into uniform ring formation. The sonication time was found to be the key parameter in ring formation. Furthermore, the flexibility of polymeric arms and electronic interactions of porphyrin–fullerene gave rise to synergistically enhanced molecular interactions, and this resulted in discrete morphologies. Key optical data, including the absorption maxima of the complexes, and microscopic studies attested to the nature and morphology of the self‐assembled complexes. This introduction of polymeric arms and sonication protocols in the porphyrin self‐assembly was expected to allow the easy formation of diverse morphologies. Because of the facile fabrication process and uniform morphology, the resulting composite architectures might show promising applications in drug‐delivery and advance materials. © 2016 Wiley Periodicals, Inc.
