Conjugated polymer:TiO2 nanocomposite solar cells based on P3HT nanoparticles.

There is widespread interest in developing efficient solar cells derived from conjugated polymers and TiO2. The conjugated polymer can act as a light harvesting dye as well as a hole transport material, and can potentially replace both the…

Polymer nanostructures through packing of spheres.

This chapter discusses about the polymer nanostructures through packing of spheres. The current protocols for the synthesis of org. nanoparticles and methods of self-assembly of nanoparticles, which may serve as a starting point for researchers…

REACTIVITY OF DISUBSTITUTED BENZOCYCLOBUTENES - MODEL COMPOUNDS OF CROSS-LINKABLE HIGH-PERFORMANCE POLYMERS

We have previously reported on the synthesis of a new 2,5-disubstituted benzocyclobutene
monomer which is capable of undergoing thermally activated cross-linking. This monomer, a derivative of
terephthalic acid, can be incorporated into the…

EFFECT OF PROCESSING PARAMETERS ON BI-SR-CA-CU-O SYSTEM

The effect of calcium content on the formation of the superconducting phases in the Bi-Sr-Ca-Cu-O systems has been examined. The influence of sintering temperature and the duration of sintering time has been studied.

Ligand substitution reactions of W6S8L6 with tricyclohexylphosphine (L=4-tert-butylpyridine or n-butylamine): P-31 NMR and structural studies of W6S8(PCy3)(n)(4-tert-butylpyridine)(6-n) (0 < n <= 6) complexes

The substitution reactions by bulky tricyclohexylphosphine (PCy3) ligands on W6S8L6 (L = 4-tert-butylpyridine or PI-butylamine) clusters were investigated to prepare clusters with mixed axial ligands for low-dimensional cluster linking. When 4- 6…

Synthesis and characterization of oxidized W6S8L6 clusters

Cationic [W6S8L6]PF6 (L = PEt3 (3), 4-tert-butylpyridine (4)) clusters, were successfully synthesized and isolated for the first time by reacting the corresponding neutral W6S8L6 (L = PEt3 (1), 4-tert-butylpyridine (2)) clusters with [Cp2Fe]PF6 as…

Packing principles of thioether derivatives of triarylamine silver salts

Tris(4-methylthiophenyl)amine, 1, has been crystallized together with three silver salts, AgOTf (silver trifluoromethane sulfonate), AgClO4, and AgSbF6. The resulting crystal structures have been determined by singlecrystal X-ray methods. All three…

AN ORGANIC-SOLID WITH WIDE CHANNELS BASED ON HYDROGEN-BONDING BETWEEN MACROCYCLES

Research on microporous solids has focused largely on inorganic materials such as aluminosilicates (zeolites), aluminophosphates, pillared clays and other layered materials(1,2). An elusive goal has been the design of new materials with specific…
