[摘要]：Two donor-acceptor hybrid star-shaped D-p-A mols. with truxene core contg. thienylethylene, triphenylamino and benzothiadiazole units were facilely developed. The absorption spectra of these compds., which almost covered the whole visible range, were tuned by changing the ratio of donor and acceptor groups. However, the PL quantum efficiencies of these compds. in solns. were dramatically reduced after the introduction of benzothiadiazole unit as acceptor chromophore.
