## Abstract Diβ__n__βalkyl substituted polyfluorenes with alkyl chain lengths of 6, 7, 8, 9, and 10 carbon atoms (PF6, PF7, PF8, PF9, and PF10) are studied in dilute solution in MCH using optical spectroscopy. Betaβphase is formed upon cooling in solutions (βΌ 7βΒ΅g mL^β1^) of PF7, PF8, and PF9 only,
