Synthesis of DDMEBT Analogues

The donor-acceptor conjugated molecules based on 1,1,4,4-tetracyanobut-1,3-dienes (TCBDs) are of substantial interest for tuning the optoelectronic properties of advanced materials. Within this group, DDMEBT possesses one of the strongest nonlinear optical responses yet observed when compared to its relatively small size. DDMEBT has already been successfully used in the construction of nonlinear optical (NLO) device, which demonstrated all-optical demultiplexing of a 170.8 Gbit/s data stream to four 42.7 Gbit/s channels using silicon-organic hybrid waveguide. Thus, the quest for better understanding of the structure - NLO properties relationship, synthesis and systematic study of the DDMEBT analogues is highly desirable.
