The title carbene (4) was generated as a highly reactive species in solution by photoirradiation of 10-diazobicyclo[6.3.0] undecapentaene (5) using a high-pressure mercury lamp. Carbene 4 reacts with benzene to afford two isomeric adducts, 10-phen...
A new tetrabenzofluorene fluorophore, containing 2,2-dicyanoethenylphenyl groups, was synthesized and subjected to photophysical studies. This substance was found to exhibit a relatively intense fluorescence in various organic solvents associated ...
The substituent effect on optical properties of 3,14-diphenyl-17,17-di(n-pentyl)tetrabenzofluorene derivatives bearing electron-withdrawing groups(NC, CH3OCO, CH3SO2, and OHC) at 4-position of the phenyl groups were investigated. These compounds w...

The redox-induced change in the bond order occurs not only in the π-conjugated systems but in the system where the σ-bond formation/cleavage is accompanied by electron transfer. Due to the dynamic geometrical changes upon redox reactions, the chro...
