Langmuir-Blodgett films of charge-transfer complexes between an amphiphilic monopyrrolo-TTF and TCNQ derivatives

Article Abstract:

An efficient method to control the electronic structure of (D(super +delta))(A(super -delta)) Langmuir-Blodgett (LB) films made from charge-transfer (CT) complexes between an amphiphilic monopyrrolo-tetrathiafulvalene (MP-TTF) derivative and different tetracyano-p-quindimethane (TCNQ) derivatives are presented. It is found that the LB films composed of mixed-stack CT complexes with tunable electronic structures are attractive candidates for the formation of nonlinear optical and dielectric materials.

Optical modeling of nanocrystalline TiO(sub 2) films

Article Abstract:

Nanocrystalline TiO(sub 2) thin films are a typical inhomogeneous medium explained by the simplest model for light scattering from a dense medium. The total scattering field is the sum of the radiation fields from all the dipoles induced in each randomly distributing nanoparticle by the electromagnetic field of incident light.
