In this study, we synthesized three novel aromatic imide-based conjugated donor(D)-σ-acceptor (A) dyad-based polymers showing different photophys. properties. These D-σ-A dyad-based polymers (e.g., BDTBT-NI, BDTBT-NDI, and BDTBT-PDI) consist of the same conjugated donor main chains (benzodithiophene-bithiophene (BDTBT)) and side chains bearing different imide acceptors (naphthalimide (NI), naphthalene diimide (NDI), or perylenediimide (PDI)). The photophys. and electrochem. characteristics of the three polymers were studied using various methods, including UV-visible absorption, steady-state fluorescence, and time-resolved fluorescence experiments as well as cyclic voltammetry. As the acceptor strength of the side chain was increased, photoinduced electron transfer from the donor backbone to the acceptor side-chain moiety was found to occur more effectively. Among the three polymers, BDTBT-PDI was found to be used as an efficient extractor and portable naked-eye sensing probe for Fe2+ ions; notably, it exhibited a “”turn-on”” fluorescence response with a detection limit at a picomolar concentration The BDTBT-PDI:Fe2+ complex was also used for ultrasensitive detection of spermine (with a Stern-Volmer constant of 6.7 × 106 M-1) in urine samples and was established as an efficient portable test kit for the real-time detection of spermine in the vapor released from fermented food samples. Finally, the “”on-off”” fluorescence behavior of BDTBT-PDI in the presence of Fe2+ and spermine enabled us to develop mol. logic gates using this polymer. In the part of experimental materials, we found many familiar compounds, such as 6-Aminohexan-1-ol(cas: 4048-33-3Product Details of 4048-33-3)
6-Aminohexan-1-ol(cas: 4048-33-3) may be used along with glutaric acid to generate poly(ester amide)s with excellent film- and fiber forming properties. It can undergo cyclization over copper supported on γ-alumina and magnesia to form hexahydro-1H-azepine.Product Details of 4048-33-3
