“…Through optimization of the input pulse parameters, dropping the amplitude down to 100 mV, only 22.5 pJ, or nearly 1 pJmm −2 , of energy is consumed per input. This can be further optimized by either modifying the electrochemical films with additives, [4] tuning the material properties by adding an electro-active species off the DTP backbone, [7,29] or adjusting the pre-synaptic input parameters. [12] In regards to biological systems, the operation of this device emulates the mechanisms of writing, reading, and forgetting.…”

“…The unitless amplitude, C, is observed as C 1 of -0.0164 and C 2 of -0.05833 for PPF while PPD displays a C 1 of 0.0149 and C 2 of 0.0747. Again, this effect can be tuned by modifying either film with additives, [4] the chemical structure, [7,29] or the pulsing parameters. [12]…”

“…Additionally, a synthetic modification of the polyDTP pendant groups has been achieved through a Cu(I)-catalyzed azide-alkyne cycloaddition (CuAAC) and is an important and simple route to alter the energetic characteristics of the resulting polymer. [29] Other reports focusing on three-terminal synaptic emulators are extensively studying PEDOT, [4,8,24] P3HT, [30,31] and graphene oxide [30,32,33] systems.…”

Electrochemical‐based memristors are highly attractive that are capable of nonvolatile analog tuning, long‐term state stability, low power consumption, device scalability, and fast switching speeds. Through the combination of film deposition techniques, i.e., vapor phase polymerization and screen printing, fabrication of a poly(4‐(6‐hexyl)‐4H‐dithieno[3,2‐b:2′,3′‐d]pyrrole) (p6DTP)‐based synaptic‐emulating three‐terminal memristor is designed. Through voltage‐driven pulse programming, and square waves with an amplitude of 100 mV and duration of 100 msec, the device exhibits a power consumption of 1 pJmm−2 per synaptic event. By analyzing the fundamental operational trends of the p6DTP‐based device, simple and advanced integrated applications can be demonstrated along with synaptic‐like responses. This effort is the first presentation of the vapor phase polymerization technique for any dithienopyrrole‐based monomers, along with the physical implementation of any memristive system as an advanced logical circuit, demonstrated here as a cascaded combinational logic gate.

A novel dithieno[3,2-b:2',3'-d]pyrrole (DTP) derivative, namely, 4-(4-(1H-pyrrol-1-yl)phenyl)-4H-dithieno[3,2-b:2',3'-d]pyrrole (DTP-Ph-Pyr) was synthesized, and its corresponding polymer (P(DTP-Ph-Pyr)) was successfully obtained via electrochemical polymerization. Electrochemical and optical properties of this novel polymer were discussed in detail. It was found that the polymer film also exhibited a reversible electrochromic behavior (orange color in the neutral state and blue color in the oxidized state) with a high optical contrast (52.5% at 950 nm) and coloration efficiency (123 cm2/C at 950 nm). Moreover, the electrochemical and optical properties of the polymer were compared with both its electrochromic P(DTP) analogues and its sister polymer structure, poly(1-(4-(1H-pyrrol-1-yl)phenyl)-2,5-di(thiophen-2-yl)-1H-pyrrole) (P(SNS-Ph-Pyr)), possessing same subunit.
