Synthesis and spectral properties of new 3,3’-bis(dipyrrolylmethene) with acetylene spacer
摘要:
Bis(2,4,7,9-tetramethyl-8-ethyldipyrrolylmethen-3-yl)acetylene dihydrobromide (H2L center dot 2HBr), new bis(dipyrrolylmethene), in whose molecule dipyrrolylmethene domains were connected through 3,3'-carbon atoms of internal pyrrole nuclei by acetylene spacer, were synthesized by original procedure. The compound was characterized by element analysis, IR, H-1 NMR, and electronic spectroscopy. The comparative analysis of spectral properties shows the reduction of the basicity of H2L ligand in comparison with the structural analogs, which contain internal methylene spacer. The quantum-chemical simulation showed that the rigid acetylene spacer gives linear structure to the H2L molecule in contrast to the spiral-shaped geometry of structural analogs with -CH2- spacer.
