Abstract:
Unconventional twisted π-electron system electro-optic (EO) chromophores/compounds, compositions and related device structures. Crystallographic analysis of several non-limiting chromophores reveals, for instance, large ring-ring dihedral twist angles and a highly charge-separated zwitterionic structure in the ground state, in both solution phase and solid-state.
Abstract:
The present teachings provide silole-based polymers that can be used as p-type semiconductors. More specifically, the present teachings provide polymers that include a repeating unit of Formula I: wherein R1, R2, R3, R4, R5R6, Z, x, and x′ are as defined herein. The present teachings also provide methods of preparing these polymers, and relate to various compositions, composites, and devices that incorporate these polymers.
Abstract:
The present invention, in one aspect, relates to a solar cell. In one embodiment, the solar cell includes an anode; an active organic layer comprising an electron-donating organic material and an electron-accepting organic material; a semiconducting layer formed between the anode and the active organic layer; and an electron-blocking layer (EBL) formed between the semiconducting layer and the active organic layer, where the EBL is transparent and adapted for blocking electron leakage from the active organic layer to the anode while transporting holes from the active organic layer to the anode.
Abstract:
A catalyst composition comprising a neutral bimetallic diphenoxydiiminate complex of group 10 metals or Ni, Pd or Pt is disclosed. The compositions can be used for the preparation of homo- and co-polymers of olefinic monomer compounds.
Abstract:
