| Research Abstract |
We have developed structurally rigid spirofluorene-indenoheterocycles involving furan, thiophene, pyrrol, imidazole, and investigated their optical and electrochemi cal properties. Rigid spirofluorene structures can enhance planarity of π-conjugated substructures and thereby reduce intermolecular interaction involving π-π interaction in solid state. Through this study, we disclosed that spiro-conjugation affects optical properties of these compounds. Newly developed compounds, which bear high thermodynamic stability, were applicable to near infrared dye or white-light emitting materials.
