Recent Developments in Phosphole‐Containing Oligo‐ and Polythiophene Materials

Abstract: The introduction of phosphorus‐containing moieties into π‐conjugated thiophene materials has been found to provide materials with strongly optimized and highly tunable optoelectronic features compared to their native thiophene counterparts. 2,5‐Diaryl‐ and 2,5‐bis(heteroaryl)phospholes as well as fused tricyclic dithieno[3,2‐b:2′,3′‐d]phospholes represent two very valuable building blocks for organic electronics as their intriguing features can be altered systematically by several, in part unique, methodologie… Show more

“…[1,2] In the present P,S-hybrid chromophores, the P-coordination to AuCl salt induces a bathochromic shift of the absorption and emission maxima (Dl abs = 31-52 nm and Dl em = 61-66 nm; for 7/8 versus 4/5) and a considerable decrease in emission efficiency (F F = 0.02-1.1 % for 7-9 versus F F = 0.6-17.6 % for 4-6). The oxygenation at the phosphorus atom causes more pronounced effects on the p-p* transitions, that is, the larger bathochromic shifts of absorption maxima (Dl abs = 61-83 nm for 10/11 versus 4/5) and complete suppression of emission.…”
