The donor-acceptor (D-A) system, which is one of the main methods implemented in material chemistry, has been widely used to construct low band-gap semiconductors. It is desirable that donor molecules have pi-conjugation in these structures. Thienothiophene (TT) derivatives have been used extensively as donors and-are preferred in optoelectronic applications. As a strong acceptor, boron unit with a vacant p orbital is linked to donor TT groups. Bulky tetraphenylethylene (TPE) subunits were appended as end groups to afford an aggregation-induced emission (ATE).
