A structure having: a molecule of carboxymethyl amylose (CMA) in a super-helical conformation; cyanine molecules on the exterior surface of the CMA arranged in a J-aggregate formation; and a chromophore molecule in the interior space of the CMA.

Ordered supramolecular system for organic photovoltaics

This invention pertains to DTT-based compounds having two-photon absorption property containing electron donors and/or electron acceptors and having cross section value &sgr; that is higher than compound AF-50.

Two-photon absorption materials based on DTT

Inclusion complexes have an organic guest molecule dye with an electron dr portion, an electron acceptor portion and a hydrophobic tail portion disposed within an organic carbohydrate host molecule. The dye in the inclusion complexes has improved thermal stability compared to itself. The complexes can be used to form a solution-cast film disposed on a substrate wherein the film thickness is up to about 20 microns and the film is made of anisotropically self-aligned (self-poled) inclusion complexes.

Nonlinear optical inclusion complexes

Polymeric metal complexes were prepared by coordination reactions of 2,5-diamino-1,4-benzenedithiol (DADT) with divalent metal halides (cobalt chloride, iron chloride, copper chloride and nickel chloride) in an aqueous alkaline solution at reflux temperatures. A black precipitate which conducted electricity was formed. Resistivity of the material increased upon exposure to air but decreased when oxygen was removed from the material.

Conductive polymers of transition-metal complexes coordinated by a

A salt of 7,7,8,8-tetracyanoquinodimethane (TCNQ) and a structural polymer re dissolved in a mutual solvent. The solution is chilled and subsequently added to a liquid with which the solvent is miscible but in which the TCNQ and polymer are less soluble. A precipitate results which is a massive, conducting, moldable substance stable in atmospheric oxygen.

Moldable electrically conductive polymer compositions

Benzimidazobenzophenanthroline type ladder polymers are doped with Lewis acids, protonic acids, potassium, or an alkali napthalide. The resulting doped polymers are useful semiconductors.

Electrically conductive ladder polymers

Phenothiazine Ladder Polymer, PTL (or di-chloro-PTL) was prepared by polydensation of 2,5-diamino-1,4-benzenedithiol with 2,5-dichloro (or 2,3,5,6-tetrachloro)-p-benzoquinone in polyphosphoric acid at 250.degree. C. Phenoxazine Ladder Polymer, POL, was prepared from 2,5-dichloro-p-phenylenediamine and 2,5-dihydroxy-p-benezoquinone under the same conditions as used for PTL synthesis. Di-chloro-POL and other derivatives can be made under a similar condition. These polymers conduct electricity.

Conductive heterocyclic ladder polymers

An electrically conductive composition comprises a poly (vinylacetal) polymer, a TCNQ salt uniformity dispersed throughout the polymer, and optionally a plasticizer.

Electrically conductive polymeric compositions

An electrically conductive polymeric composition is fabricated by dispers polymeric ether complexes of TCNQ salts within a flexible, thermoplastic polymer matrix. The compositions form flexible, homogeneous, films which exhibit substantially superior properties over currently available TCNQ salt based systems.

Flexible semiconductive polymers

Electrically conductive polymeric compositions are obtained by incorporat crown ether complexes of TCNQ salts in a polymer selected from the class consisting of polycarbonates and poly(alkyl alkacrylates). The compositions can be formed into semiconductive films useful in the fabrication of e.g. thermoresistors and electronic devices.

An olefinic polymerization initiator comprising a micellar complex of a mll-forming detergent selected from the class consisting of C.sub.10 to C.sub.18 aliphatic-trimethylammonium bromide, C.sub.10 to C.sub.18 aliphatic-trimethylammonium chloride, hexadecyl pyridinium bromide, and hexadecylpyridinium chloride, and a bisulfite in a detergent-to-bisulfite mole ratio from 1:2 to 50:1.
