Comparison of 2-Arylnaphtho[2,3-b]phospholes and 2-Arylbenzo[b]phospholes: Effects of 2-Aryl Groups and Fused Arene Moieties on Their Optical and Photophysical Properties.
Suzuki-Miyaura cross-coupling reactions were used in the divergent synthesis of a series of 2-arylnaphtho[2,3-b]phosphole P-oxides and their benzo[b]phosphole counterparts. We elucidated the electronic and steric effects of the 2-aryl groups and fused arene moieties on the optical and photophysical properties of these two types of phosphole-based π-systems.
