The Synthesis and Optical Properties of Two BOPIMs Containing N,N-Dimethylaminophenyl Groups

The synthesis and nonlinear optical properties of two N, N-dimethylaminophenyl substituted BOPIMs, BOPIM-ma and BOPIM-dma, were investigated. A more significant solvatochromic shift is achieved in BOPIM-ma, which is more sensitive to solven. It is distinct that the energy gap between the HOMO and LUMO for BOPIM-ma, 2.503 ev, is larger than that of BOIM-dma, 2.449 ev, an indication of the functionalization of N,N-dimethylaminophenyl group.
