Efficient Synthesis and Characterization of Dibenzo[a,m]rubicenes and Tetrabenzo[a,f,r,m]rubicenes
摘要:
We report an efficient synthesis of dibenzo[a,m]rubicenes and tetrabenzo[a,f,r,m]rubicenes involving ICL-mediated benzannulation of 1,4-diphenyl-2,5-dialkynylbenzene 5 as the key step. Preliminary data on the photophysical properties of these new indeno-PAHs are reported.
