Abstract

As a continuing effort to explore molecular systems suitable to test the one-dimensional Kramers' theory, the conformational change of bis(9-fluorenyl)methane (9-BFM) as studied in n-alkane solvents, using the time-correlated single photon counting method. The excimer formation processes of this molecule consist of a fast ( τF ≈ 1 ns) and a relatively slow (τF ≈ 5 ns) channel at ambient temperature. The viscosity dependence is mild as observed previously in bifluorene and the Arrhenius plot gives the activation energy of 3.7 kcal/mol for the slow intramolecular excimer formation process.
