J. Kowalik et Lm. Tolbert, Unusual solvatochromism in phosphonylated polythiophenes. Poly[3-(11-diethylphosphorylundecyl)thiophene], CHEM COMMUN, (10), 2000, pp. 877-878
Highly stereoregular poly[3-(11-diethylphosphorylundecyl)thiophene] 2 is so
luble in both aprotic and protic solvents, yet displays a remarkable solvat
ochromism involving a hydrogen bond network with the phosphonate moiety.
