“…The mechanism of the reactions and the properties of the obtained layered products have been intensively investigated for systems consisting of inorganic layered solids as the host in combination with various kinds of inorganic and organic components as the guest species. [133][134][135][136][137][138][139][140][141] In contrast to a variety of intercalation hosts made of inorganic compounds and inorganic-organic hybrids, very few examples of intercalation systems using organic compounds as both the host and guest are known. A limited number of organic crystals have been reported as the organic mimics of clay.…”

ABSTRACT:In this review article, polymer structure control and organic material design based on polymer crystal engineering are described. The structures and properties of crystalline materials are designed using pre-organized molecules through various intermolecular interactions such as hydrogen bonds, π · · · π, CH/π, CH/O, and halogen interactions. Here, we describe the features and mechanisms of the topochemical polymerization of 1,3-diene monomers including some ester, ammonium, and amide derivatives of muconic and sorbic acids, which are 1,3-diene di-and monocarboxylic acid derivatives, respectively. We have proposed the topochemical polymerization principles for diene monomers on the basis of the crystallographic data accumulated for various kinds of diene monomers. The combination of several intermolecular interactions is useful for the construction of molecular packing appropriate for 5 Å stacking in order to facilitate the topochemical polymerization in the crystalline state. We refer to the control of polymer chain structure including tacticity, molecular weight, and ladder structure, and also polymer crystal structures, as well as the organic intercalation system using layered polymer crystals obtained by the topochemical polymerization. A totally solvent-free system for the synthesis of layered polymer crystals is also described.KEY WORDS Topochemical Polymerization / Solid-State Reaction / Crystal Engineering / Supramolecular Synthon / Stereoregular Polymer / Controlled Radical Polymerization / X-Ray Single Crystal Structure Analysis / Intercalation / Controlled polymer synthesis, including the control of polymer chain structures such as molecular weight, molecular weight distribution, chain-end structure, branching, regioselectivity, and stereoselectivity, has great potential for the design of macromolecular architecture leading to advanced nano-materials and devices. [1][2][3][4][5][6][7][8][9][10][11] All the features and functions of polymers importantly depend on primary chain structures and the manner of polymer chain assembly in crystalline and non-crystalline solids, or in a condensed state. Therefore, the control of polymer chain structures in polymer synthesis can hardly be overestimated for the architecture of advanced polymeric materials.Especially, the stereochemistry of polymers has received significant attention in both fundamental and applied fields ever since the first discoveries of stereoregular polymers in the 1950s. 12-14 Highly controlled stereospecific polymerization has been well established by coordination polymerization of olefins and diene monomers and by anionic polymerization of certain types of polar monomers. Radical polymerization is the most important and convenient process for the production of various kinds of vinyl and diene polymers due to recent achievements in well-controlled polymerizations in addition to the classical advantages of the radical process. [15][16][17][18][19][20][21][22] There are two fundamentally different ways to control of the chain structu...

“…Such an approach can result in the design and development of hybrid organic-inorganic materials with tailormade properties. These materials can function as molecular sieves of controlled pore size [39], shape-selective catalysts [40,41], molecular sorbents [42,43] and stationary phases for chiral molecular recognition [2,44].…”

The art of designing and synthesizing organic molecules has reached very high levels of sophistication, based on a relatively simple set of rules that guide both the invention and synthesis of new compounds. This set of rules is construed as the rational synthetic method of organic chemistry. As material chemists confronted to the task of building new solid structures with tailored chemical properties, we do inevitably need to develop some rational approach and to establish the corresponding set of rules allowing a realistic level of predictive knowledge in the construction of solid scaffolds. These conditions are reasonably accomplished by the use of layered salts of tetravalent transition metals, namely zirconium phosphate (ZrP). The placing of organic molecules between the layers of ZrP is quite straightforward, can easily be controlled and leads to enduring, solid materials where the confinement makes the organic molecules to show new properties at the supramolecular level. The chemistry of metal phosphates/phosphonates will be detailed in relation with the following topics: (i) molecular recognition, (ii) chemically driven porosity changes, (iii) chiral memory and supramolecular chirality, (iv) luminescence signalling, (v) photo-induced electron-transfer processes, (vi) hydrogen storage, (vii) confinement of drugs and (viii) metal uptake.

“…optical sensorial devices, can be obtained by the immobilization of chromophore or luminescent species onto the surface of optical fibers or windows. A number of electrochemical, electronic and photonic devices can be devised, based on the molecular interfaces acting as sensorial elements or tranduscers (Mallouk & Gavin 1998, Wong 1994 as exemplified in Figure 1. In our laboratory, the development of molecular interfaces has been conducted in three different ways: a) generation of Prussian blue films, b) self-assembly of molecular films and layers and c) intercalation of molecular species into lamellar, conducting metal-oxide films.…”

Supramolecular chemistry deals with the association of several chemical species, in an organized way and according to well defined purposes. Based on a molecular engineering approach, supramolecular structures can be designed from pre-formed building blocks, providing a promising route from chemistry to molecular nanotechnology. New supramolecular systems have been assembled in our laboratory with the use of bridging unities such as tetrapyridylporphyrins, porphyrazines and polypyrazines, connecting transition metal complexes and clusters. These systems display a very exciting electrochemical and catalytic behavior, and interact with DNA, generating 1 O 2 and leading to efficient oxidative clivage for photodynamic terapy applications. Molecular interfaces have been developed, exhibiting photocurrent response in the presence of visible-UV light, and rectifying properties in the presence of electroactive species. Successful applications of the supramolecular species in chemical and bio-sensors have been developed.
