aromatics. Fluoranthenes 9 (or 13) are easily accessible in good to excellent yields (75-99%; 18 examples) from the reaction of symmetric (or asymmetric) diynes 4 and alkynes 5 (or norbornadiene) in the presence of Wilkinson's catalyst. This formal [(2+2)+2] cycloaddition can also be applied to generate various indenocorannulenes 28 from 2,3-diethynylcorannulene derivatives 27 and alkynes 5. The indenocorannulenes
In this study, we report synthesis of symmetrically and non-symmetrically functionalized fluoranthene-based blue fluorescent molecular materials for non-doped electroluminescent devices.

Electroluminescent materials based on the fluoranthene core and containing triarylamine segments were synthesized and characterized by IR, NMR, UV-Vis, and emission spectroscopic, electrochemical, and thermal studies. The electronic absorption and emission characteristics of the new functional materials were affected by the nature of the chromophore present on the fluoranthene nucleus. Incorporation of

photophysical properties of M1 and T1 were explored in solution, solid-state and their AIEE phenomenon was studied in THF/water systems. Both the compounds show strong sky-blue emission at 453 nm (M1) and 460 nm (T1). The fluorescence lifetime and quantum yields are varied significantly in the aggregated form. The emissionenhancement ascribed due to restricted intramolecular rotation (RIR) of thiophene/phenyl
An intramolecular charge transfer (ICT) state evolves via excited state structural change and solvent reorganization, where the charge distribution in the excited state is markedly different from that in the ground state. Due to its ubiquitous nature, this intriguing photophysical phenomenon offers promising applications in the realm of optoelectronics. Judicious choice of donor–acceptor-based (D–A)
