fluorophore having the same core skeleton) values (<20 nm) in full visible region (λem: 400–650 nm), the high log ε (>4.5), and the high Φf (>0.6), we investigated molecular design, synthesis, and light-emitting characteristics of the π-conjugated molecules (D/A-BPBs) consisting of 1,4-bis(phenylethynyl)benzene (BPB) modified by donor groups (OMe, SMe, NMe2, and NPh2) and an acceptor group (CN). As a result
为了创建全彩虹荧光团(WRF),其具有小Δλ
