Reliable Methods

In order to develop reliable methods for the synthesis of various 5-substituted-8-oxyquinoline derivatives for the preparation of Alq3-type complexes, we have improved the reaction conditions on some syntheses described in the literature, successfully synthesized new ligands based on quinolin-8-ol and characterized their chemical structures by NMR. Some of the synthesized quinolin-8-ol derivatives containing incorporated bulky triphenyl or tert-butyl groups showed blue luminescence in the solid state due to the possible aggregation induced emission enhancement (AIEE) with a maximum wavelength around 510 nm. More detailed light-emission property investigation of the mentioned bulky group containing compounds is currently underway.

Fluorescent Molecules

Fluorescent molecules based on a fluorinated isoxazole scaffold were provided for the synthetic methods and their photochemical properties.  Simple 3,5-diarylisoxazoles led to increasing the fluorescent intensity and exhibited a redshift in the emission intensity by introducing a fluorine atom.  α-Fluorinated boron ketoiminates (F-BKIs) derived from a ring opening reaction of 4-fluoroisoxazoles were also synthesized and exhibited a highly fluorescent luminescence as a new aggregation-induced emission (AIE) fluorophore.

We present here the simple procedure for synthesizing elongated fibers like porphyrin aggregates. Usually whenever the aggregation in dye molecules takes place the emission always tends to quench. In this work we explore and discuss the unusual enhanced emission property of these aggregates. The nanofibers of porphyrin were characterized with the help of atomic force microscopy and UV-vis spectroscopy whereas photoluminescence spectroscopy was used to check their emission property.
