“…Combining the BF and vapor deposition processes, silver spikes arrays with triangular sharp have been fabricated showing strong enhanced Raman scattering of rhodamine 6G [220]. Other strategies involve the electrodeposition of gold nanoparticles [221] or the incorporation of the nanoparticles in the polymeric solution [173]. Recently, SERS substrates have been created by in situ generation and immobilization of Ag NPs nanoparticles at the surface of honeycomb films based on PDMAEMA [184].…”

The creation of porous polymer surfaces is a center of interest in current research. Porous surfaces possess extremely high specific surface areas, thus allowing their employment in a large variety of applications including electronics, photonics or biotechnology [1,2]. Pore size and distribution can play a major role in selective transportation or in insulation processes amongst others [3]. Those porous materials with cavities in the micrometer size range are interesting in catalysis, sensors, membrane preparation or as scaffolds for composite materials. Moreover porous materials with pore dimensions comparable to the wavelength of visible light are of interest as photonic band-gaps and optical stop-bands.Structures with micrometer or submicrometer dimensions can be created using different templating methods [4,5]. A large variety of approaches have been developed and employed to prepare microporous structured materials, including the use of templates such as ordered arrays of colloidal particles to produce inverse opal structures [6][7][8][9], from transformed polymeric sphere arrays [10,11], using emulsion droplets as templates [12], employing natural biological templates [13][14][15][16], by

“…Recently, our group has developed a simpler method to construct highly ordered porous honeycomb films of surfactant-encapsulated polyoxometalates at an air/water interface without any moist airflow across the solution surface. [31][32][33] This method can easily transfer the films onto different substrates for further characterization and application, such as directionally electrodepositing gold nanoparticles into honeycomb macropores [34] and preparing freestanding honeycomb films. [35] Herein, we extend the breath-figure method to an amphiphilic ferrocenyl-based oligomer 1 with ferrocene units in the main chain and hydrophobic cholesteryl groups as side chains (Scheme 1; the synthesis and characterization of the oligomer are described elsewhere [36] ).…”

Honeycomb-patterned polymer films with tunable pore size and regularity of ordered two- or three-dimensional hexagonal arrays have met with widespread interest in recent years in different areas, for instance as separation and superhydrophobic materials. Herein, 2D honeycomb-patterned films of amphiphilic ferrocenyl-based oligomer with cholesterol as side chains were prepared by the breath-figure method on solid surfaces and their surface-wetting behavior were tested. These films can be simply prepared by spreading a mixture of polymer and organic solvents on a solid surface under moist airflow and at an air/water interface without any extra moist airflow. An ordered 2D hexagonal array of pores with monodisperse size distribution can be obtained over a large area by changing various influencing factors, including humidity, wet volume, concentration, selective solvent, and spreading method, which provides a facile route to regulate the morphology of patterned porous films. The surface-wetting behavior indicates that a higher hydrophobicity of the ferrocenyl-based oligomer honeycomb films can be obtained by modulating the pore size and regularity. It is expected that this could promote the potential application of ordered porous polymer films in hydrophobic materials and biochemistry.

Honeycomb-structured films represent an intriguing class of two-dimensional porous materials. Specifically, polyoxometalate (POM) macroanions can be introduced into these films by complexing with oppositely charged, double-tailed surfactants. Here highly-ordered honeycomb structures are reported that can be constructed by the complexes between POMs and a room temperature ionic liquid (IL1) having an imidazolium moiety in the middle and a naphthyl unit and a branched aliphatic chain at the ends. The complexes can be produced through phase transfer between an aqueous solution of POMs (typically {Mo Fe }) and a CS (or chloroform) solution of IL1. Based on the intrinsic properties of {Mo Fe } and the functional groups of the IL1, the honeycomb structures show multiple functions with bright photoluminescence and rich electrochemical properties. This work shows that by simply engineering the organic ligands involved in the POM-based inorganic-organic complexes, supramolecular structures with improved properties and wide applications can be obtained.
