Many π-conjugated systems containing hetero-elements such as acceptor three-coordinate boron[1] or hypervalent phosphorus[2] for instance, display strong linear and/or non-linear optical properties, making them suitable for many potential applications. Interestingly, the electronic properties of these compounds can be easily tuned by varying the surrounding substituents tethered to the hetero-elements. Density-functional theory (DFT) calculations of the ground and excited states of a selection of such boron- or phosphorus-containing systems were carried out to analyze and interpret some of their properties.[3] Case studies will be shown and discussed.
