摘要：

The pattern of the photoreactions of DBMBF(2) with a cyclic diene is highly dependent on solvent nature, giving mainly the dimers of dienes in polar solvents but cycloadduct in non-polar solvents. The quantum yields of the adduct(Phi(A)) correlate smoothly with an empirical polarity constant (E(T)(N)) in spite of exciplex formations with aromatic solvents.
