BOBzBT2 organic pentamer for the observation of resistive switching mechanism and strong coupling regime

We introduce a novel organic pentamer, 1,4-bis[2(5-thiophen-2-yl)-1-benzothiophene]-2,5dioctyloxybenzene (BOBzBT2) that can be used to observe two interesting electrical and optical phenomena, namely, the resistive switching mechanism and the strong coupling regime. The stability of the pentamer, resulted from the addition of dioctyloxy-substituents along with its elongated π-conjugation backbones, allows us to induce the resistive switching mechanism on a commercially screen-printed electrode (SPE) strip. On the other hand, the addition of thiophene units in the pentamer enhanced its optical nonlinearities and the presence of bis-donor groups and contributed to a large efficiency of two-photon absorption yield. As a result, we were able to demonstrate a room temperature strong coupling regime with a large Rabi splitting using surface plasmon resonance (SPR)-Otto configuration.
