This lecture overviews our studies on electronics and photonics of fluorene-based and related π-conjugated oligomers and polymers: from design and synthesis to physical studies and materials applications in electronic devices. I will discuss the following aspects in these researches:
(1) star-shaped conjugated architectures: toward increased dimensionality of conjugated systems;
(2) dibenzothiophene-S,S-dioxides and 4,5-diazafluorenes as electron-deficient fluorene heteroanalogs for electron transport and charge transfer materials;
(3) dual emission in conjugated systems and its use for broadening electroluminescence toward single polymer white-light OLEDs;
(4) conjugated oligomers / polymers as fluorescent sensors for metal cations;
(5) tuning the electronic energy levels and the emission color through side-chain functionalization.
