“…[52] Rod-coil or coilrod-coil block copolymers offer another way to control assembly processes through variation of the number, nature, and size of the coil units. [53][54][55][56][57][58][59][60][61][62][63][64][65] A wide range of topologies, including sheets of mushroomlike aggregates; [56,64] spherical, vesicular, cyclindrical, and lamellar aggregates; [58][59][60][61]66] and porous membranes, [53,62,63] have been obtained in this way.…”

The development of nanotechnology using organic materials is one of the most intellectually and commercially exciting stories of our times. Advances in synthetic chemistry and in methods for the investigation and manipulation of individual molecules and small ensembles of molecules have produced major advances in the field of organic nanomaterials. The new insights into the optical and electronic properties of molecules obtained by means of single-molecule spectroscopy and scanning probe microscopy have spurred chemists to conceive and make novel molecular and supramolecular designs. Methods have also been sought to exploit the properties of these materials in optoelectronic devices, and prototypes and models for new nanoscale devices have been demonstrated. This Review aims to show how the interaction between synthetic chemistry and spectroscopy has driven the field of organic nanomaterials forward towards the ultimate goal of new technology.

“…Biological systems are, therefore, far more advanced than artificial machines and are worthy of being pursued and mimicked. Peptide mimics and nucleic acid mimics have been widely researched including the construction of a numerous nano‐objects 1–8. Among biological components, biomembranes are rather understandable targets, although they are composed of complicated mixtures of lipids, proteins, and sugars.…”

The hybridization of lipid membranes with inorganic silica-based framework results in mechanically stable biomembrane mimics. This account describes three types of silica-based biomimetic membranes. As the first example, a Langmuir monolayer of dialkylalkoxysilane was polymerized and immobilized onto a porous glass plate. Permeability through the monolayer-immobilized glass was regulated by phase transition of the immobilized monolayer. In the second example, spherical vesicles covalently attached to a silica cover layer (Cerasome) were prepared. The Cerasome was stable enough to be assembled into layer-by-layer films without destruction of its vesicular structure. This material could be an example of the multicellular assembly. Mesoporous silica films densely filling peptide assemblies (Proteosilica) are introduced as the third example. The Proteosilica was synthesized as a transparent film through template sol-gel reaction using amphiphilic peptides.

“…This observed transition is irreversible and only occurred during the first heating run; it is attributed to an irreversible change from a 7/2 to an 18/5 a-helical conformation [33]. At higher temperature, no other transition could be observed for PBLG until its degradation [34,35]. It can be seen that T g of the PLLA 2 -b-PBLG copolymers shifts slightly to a higher temperature with increasing chain length of PBLG, probably because the mobility of PLLA 2 chains is constrained.…”
