Electric Literature of 1034-39-5, Children learn through play, and they learn more than adults might expect. Science experiments are a great way to spark their curiosity, get their minds active, and encourage them to do something that doesn’t involve a screen. 1034-39-5, C18H15Br2P. A document type is Article, introducing its new discovery.
A series of donor-pi-acceptor systems incorporating a tetrathiafulvalene moiety as the donating unit have been designed and synthesized. The efficiency of the imine (-C=N-) bond as a conjugated pi-linker in promoting intramolecular charge transfer is demonstrated and supported by calculations at the B3LYP/6-31G(d,p) level of theory. This property has been explored in the case of pyridyl-substituted systems which exhibit in particular a high binding affinity and selectivity for Pb2+ (log K = 3.5 in CH 2Cl2/CH3CN), as shown by UV/Vis and 1H NMR titrations as well as by remarkable colorimetric and electrochemical signaling.
