A highly selective and sensitive probe based on benzo[1,2-b:4,5-b′]dithiophene: Synthesis, detection for Cu(II) and self-assembly

A novel turn-off probe for copper(II) containing benzo[1,2-b:4,5-b′]dithiophene (BDT) and two picolinamide units was synthesized. In this probe, two picolinamide units complex with one Cu2+ ion and two nitrogen atoms in each picolinamide unit coordinate with Cu2+, which is verified by DFT calculation. Its fluorescence quantum yield is 0.43 and the detection limit is as low as 2.4×10-8 mol/L. The results show that the probe displays good selectivity for Cu2+ over other ions (Mn2+, Pb2+, Cr3+, Zn2+, Ni2+, K+, Ca2+, Ag+, Mg2+, Fe3+, Fe2+, Hg2+, Al3+, Cd2+, Pd2+, Co2+). Furthermore, the probe induced by Cu2+ and the π-π interaction of the aromatic unit can also form rod structure assembly, which can be observed by scanning electron microscopy (SEM).

A Benzodithiophene-Based Fluorescence Probe for Rapid Detection of Fluoride Ion

A novel and simple fluorescence probe was synthesized from benzo[1,2-b:4,5-b′]dithiophene (BDT) and trimethylsilylethyne via Sonogashira reaction, and showed highly selective and sensitive fluorescence decreasing response towards F?. The probe molecule turned to a weakly fluorescent terminal alkyne moiety because its trimethylsilyl (TMS) group was cleaved by fluoride, which was proved by1H NMR titration. Whereas no distinct fluorescent changes were observed with the addition of other anions, such as Cl?, Br?, I?, AcO?and H2PO4?. Upon the addition of F?, the maximum fluorescence emission wavelength shifted from 460 nm to 450 nm with a decrease of fluorescence intensity by 40% within 20 s. Moreover, the detection limit towards F?was calculated to be as low as 73.5 nmol/L.

Ethynylene-linked oligomers based on benzodithiophene: Synthesis and photoelectric properties

Two conjugated ethynyl-linked oligomers, oligo(benzodithiophene-ethynylene- benzothiadiazole) (O1) and oligo(benzodithiophene-ethynylene-carbazole) (O2), were synthesized by Sonogashira coupling reaction. Their degrees of polymerization were 7 and 10, respectively. Their photophysical and electrochemical properties were investigated. O1 exhibitd two strong absorption bands at 404 nm and 483 nm, and O2 at 401 nm and 429 nm. The results of UV-Vis, cyclic voltammetry (CV) and theoretical calculations showed that O1 has a narrower band gap than O2. The conductivities of O1 and O2 were 1.05×10-15 and 6.98×10-16 S/cm, respectively, and would increase to 1.23×10-10 and 1.05×10 -10 S/cm after doping with iodine. Two oligomers based on benzodithiophene with different structures and energy levels. Copyright
