Theoretical calculation has been performed for the photoinduced electron transfer between chloranil and biphenylene.The center-center distance between the donor and acceptor of the complex has been optimized by using MP2 method, and the counterpoise method has been adopted to consider the basis set superposition error.Four lowlying excited singlet states of chloranil-biphenylene (CL-BP) complex have been investigated by using the method of configuration interaction singles.It is concluded that CL and BP can form a stable electron donor-acceptor complex and light absorption can directly produce excited charge transfer state.Based on the approximation of spherical cavity and point dipole, the solvation correction of the absorption spectrum has been made for the charge transfer transition.The red shift of 0.443 eV was predicted.The result shows that the theoretical calculation agrees well with the experimental observations.

Key words: ab initio, photoinduced electron transfer, charge transfer state, spectral shift
