Synthesis of Novel Organic Conjugated Small Molecules Containing Heteroatoms (N, S)
Abstract: A series of organic conjugated small molecules containing heteroatoms (N, S) were designed and synthesized. The different alkyl chains can be introduced through reaction of the lithiated thiophene with corresponding alkyl halide at low temperature. After bromination, the resulting bromo-intermediates can be smoothly converted into corresponding Grignard reagent. Afterwards, the as-prepared Grignard reagents were treated with 1,2,4,5-tetra(S-(pyridine-2’-yl))ben- zenetetrathioate, and then reacted with hydrazine hydrate to afford the target compounds. Upon aforementioned syn-thetic strategy, the physical characters of the target molecules can be fine-tuned by efficient introduction of the different alkyl substituents in the periphery of the conjugated backbone. The UV-Vis absorption spectra of these molecules in dichloromethane solution revealed three maximum absorption peaks between 260 and 600 nm.
