We report a new tri-section stepped-impedance resonator (SIR) that features a short and low-impedance section inserted in a two-section SIR. The inserted section not only makes the resonator more ...

Giant π-conjugated macrocycles composed of thiophene, acetylene, and ethylene subunits arranged as 72π, 108π, 144π, and 180π electron systems were synthesized and analyzed for their one- and ...
