Abstract
Electroluminescent compounds, devices and methods for making the foregoing are disclosed, which employ a novel topological strategy for designing amorphous molecular solids suitable for forming thin films in optoelectronic devices. In this approach chromophores are attached to a tetrahdral point of convergence.
