Abstract

© 2021 Elsevier B.V.Organic conjugated compounds containing various substituents 3-amino-2,4-dicyano-1-aryl-9H-fluorene and 1-dicyanomethylene-2-aryl-indone derivatives were successfully obtained. Various routes and synthesis methods, such as one-pot, multi-step, and microwave irradiation (MWI), were explored for efficiency. Spectroscopic methods were used to characterize of the synthesized compounds. Furthermore (E)-2-(2-(anthracen-9-ylmethylene)-2,3-dihydro-1H-inden-1-ylidene) malononitrile (2b) compound which exhibited a crystal structure was also characterized via X-ray technique. The thermogravimetric analysis (TGA) was used to investigate the thermal stability. Finally, the photophysical properties of the synthesized compounds were also investigated using UV–vis and fluorescence.
