| Outline of Final Research Achievements |
(1) As a model study for the synthesis of as-indacene derivatives, an entirely new synthetic route to s-indacene derivatives was successfully developed.t Because this method is applicable to the synthesis of as-indacene derivatives, it has became feasible to achieve the synthesis of the final target.
(2) In order to synthesize as-indacenes fused by thiophene rings, an o-quinodimethane type isomer was successfully generated, giving a dimer derived by 4+4 cycloaddition of the reactive intermediate. Attempts to kinetically stabilize the system by introducing bulky substituents failed to isolate the desired product, indicating the limit of kinetic stability of this system. In addition, two dihydro-o-quinodimethane type derivatives were synthesized and their photophysical properties were investigated.
