Stack array

The helix can be viewed as a stacked array of pepdde planes hinged at the (X-carbons and approximately parallel to die helix.

TCNQ-Polyphosphazene Systems. Tetracyanoquinodimethane (XX) salts crystallize in the form of stacked arrays that allow electrical semiconductivity (42). Although this phenomenon has been studied in many laboratories, it has not been possible to fabricate conductive films or wires from these substances because of the brittleness that is characteristic of organic single crystals. However, it seemed possible that, if the flexibility and ease of fabrication of many polyphosphazenes could be combined with the electrical properties of TCNQ, conducting polymers might be accessible. 

In a real biological system, DNA is mostly surrounded by many proteins. Protein binding to DNA involves a number of hydrogen bonds and electrostatic contacts between two biopolymers, and induces not only structural deviation from the typical B-form structure, but also electronic perturbation of the -stacked array of base pairs. We tackled the electronic effects of protein binding on the efficiency of hole transport by using a restriction en-...

The crystals of radical 29, which are diamagnetic by electron spin resonance (ESR), consist of cofacial dimers with four dimers per unit cell linked by two long, albeit unequal (3.053 and 3.309 A), interannular S-S bond <2005IC1837>. This mode of association has not hitherto been observed for 1,2,3-dithiazolyls. Dimers of radical 29 do not form 7i-stacked arrays instead, they adopt the closed packed herringbone arrangement which allows for a clustering of the radical heads so as to maximize S- -S and S- -N contacts. 

A, while that between the pairs is 3.383(6) A. The 7r-stacked arrays of cations are linked by centrosymmetric pairs of Se(2)—N(l ) contacts, thereby generating ribbons running along the y-direction. These four-center Se—N supramolecular synthons, which are common in diselenadiazolylium salts and diselenadiazolyl radicals, are likely to dominate the solid-state structures of reduced diselenazolyl materials. 

Incorporation of an alkyne moiety within the lipophilic core (e.g., 23) imparts helical and scissors-like morphology to the stacked array (e.g., 24 and 25, respectively). Disclike, benzene-based arborols have also been reported1891 to form //-bonded aggregates, or networks, comprised of approximately 50-60 dendrimers. The approximation is based on network diameters determined from electron microscopy. 

Immunization with homopolynucleotide-MBSA complexes gives rise to antibodies that are specific for an oligonucleotide segment of the polymer. They probably recognize a number of bases in sequence, perhaps in a stacked array. Poly(I), poly(C), and poly(A) each induce specific antibodies that show little cross-reaction with the other homopolynucleotides, and slight cross-reaction with denatured DNA. ...
