Abstract
Silicon- and germanium-bridged bipyridyls
were prepared, and their
optical and electrochemical properties were investigated. It was found
that they exhibited enhanced electron deficiency and phosphorescence
properties in comparison to parent bipyridyl. The single-crystal structure
of a dipyridinosilole and results of DFT calculations on models are
also described
