Supramolecular Luminescence from Oligofluorenol-Based Supramolecular Polymer Semiconductors: Experimental Investigation | Chapter 7 | New Innovations in Chemistry and Biochemistry Vol. 1

 Intermolecular forces cause supramolecular luminescence, which is caused by non-covalent exciton behaviours of active -segments in supramolecular entities or aggregates. Suzuki coupling as a supramolecular semiconductor was used to produce a -conjugated oligofluorenol with self-complementary double hydrogen bonds. Concentration-dependent nuclear magnetic resonance (NMR) and dynamic light scattering were used to confirm terfluorenol-based random supramolecular polymers (DLS). Titration experiments indicated that the photoluminescence spectra of the TFOH-1 solution have a green emission band (g-band) at around 520 nm with reversible characteristics. Supramolecular luminescence of TFOH-1 thin films provides strong support for g-band aggregation. The existence of polyfluorene ketone defects appears to be a sufficient rather than a sufficient-necessary condition for the g-band, according to our findings. Non-covalent network antecedents in the ink are also important for thin-film optoelectronic behaviours and phase morphologies, according to our findings. Organic devices will be pushed into supramolecular optoelectronics, spintronics, and mechatronics through supramolecular electroluminescence.
