Formation of Helical Mesopores in Organic Polymer Matrices

Abstract

Self-assembled helices were used as templates to form helical mesopores in a polymeric matrix. The template was formed from the self-association of 3,5-bis(5-hexylcarbamoylpentyloxy)benzoic acid decyl ester in ethylene glycol diacrylate. The monomer was photopolymerized, and the resulting resin was extracted to remove the template. The helical shape of the pores was proven by TEM and tomographic studies. The ability to form material with high specific areas using tubular templates from the same molecules was also shown.

Lost in translation? Chirality effects in the self-assembly of nanostructured gel-phase materials

“…In this way, the gelator can exert a templating effect. 47 Me´sini and co-workers employed gelator 12, known to form helical fibres (the gelator is actually achiral, and so gave rise to a statistical mixture of right-handed and left-handed helices). This gelator formed gels in ethylene glycol diacrylate at concentrations of 5% by weight.…”

Template‐Free Tuning of Nanopores in Carbonaceous Polymers through Ionothermal Synthesis

“…Generally, mesoporous materials such as silica are synthesized through a soft templating approach, [13][14][15][16][17] whereas carbons or polymer networks usually require the use of silica-based hard templates, [1,[18][19][20] but some reports with a soft templating approach were recently reported as well. [21][22][23] Although this methodology led to interesting materials, it is practically a ''no-go'' for industrial applications because of its complexity and high cost. Therefore, a template-free preparation of mesoporous organic materials is still highly desired.…”

Fe(III)-containing mesoporous poly-(p-phenylenediamine): Synthesis, characterization and magnetic properties

“…Lower amount of Fe(III) in sample 2A vis-à-vis 1A could be responsible for poor cross-linking in the framework resulting in a lower surface area. Mesoporous organic materials synthesized by surfactant templating methods usually have low surface areas [29] vis-à-vis purely inorganic [23,30] or organic-inorganic composite [31] or organic-inorganic hybrid mesoporous materials [32]. BET surface area for sample 3, synthesized without any SDA (Fig.…”
