摘要：
The excited-state structure of beta-phase poly(9,9-dioctylfluorene) (F8) is investigated by means of optical absorption and electroabsorption spectroscopies in order to reveal the effect of beta-phase formation on the excited-state structure in F8. The excited-state structure of beta-phase F8 consists of six essential states, where two new B-u states are formed on the four essential states of alpha-phase F8. The two additional B-u states result from the energy splitting of the B-u states of alpha-phase F8, caused by intermolecular interaction in P-phase F8. (c) 2007 Elsevier B.V. All rights reserved.
