Get more from a larger pi: Four π-extended phosphindolizine derivatives have been synthesized and characterized. The positions and the additional fusion of benzene rings (colored in the figure) considerably changed the molecular structures, the HOMO and LUMO energy levels, and the photoluminescence properties.
