Abstract Ubiquitous electronic gadgets in lives have led to an increase waste (e‐waste), posing a threat the environment and ecology that must be addressed. This work demonstrates use of gelatin, natural protein, for development flexible biodegradable substrates synaptic transistors using same material as gate dielectric. The fabricated p‐channel exhibit high electrical stability exceptional characteristics through spike timing dependent plasticity (STDP), voltage (SVDP), number (SNDP), respectively upon variation post‐synaptic current (PSC) with time, amplitude, stimuli. These devices pulse paired facilitation (PPF) relaxation time constants range ≈10 ms regulating modulation amplitude 1 greatly resembling biological synapse. Study on variability among distinct over multiple cycles demonstrate outstanding repeatability plasticity. showcase significant PSC values almost linear SNDP, while consuming ultralow power ≈11.7 fJ. Excellent is observed when subjected bending sequences. Complete dissolution these aqueous environments hour without any alteration temperature or pH confirms excellent biodegradability leading toward transient neuromorphic circuits systems adhere concepts circular economy.

The construction of high-performance n-type semiconductors is crucial for the advancement organic electronics. As an attractive semiconductor, molecular systems based on perylene diimide derivatives (PDIs) have been extensively investigated over recent years. Owing to fascinating aggregated structure and high performance, S-heterocyclic annulated PDIs (SPDIs) are receiving increasing attention. However, relationship between electrical properties SPDIs has not deeply revealed, restricting progress PDI-based Here, we developed two novel with linear dendronized substituents in imide position, named SPDI SPDI, respectively. A series structural property characterizations indicated that formed a long-range-ordered crystalline helical supramolecular columns, while longer alkyl side chains, 3D-ordered at low temperature, which transformed into hexagonal columnar liquid crystal temperature. Moreover, no significant charge carrier transport signal was examined had mobility 3.5 × 10−3 cm2 V−1 s−1 2.1 state, These findings highlight importance structure–function PDIs, also offer useful roadmaps design electronics down-to-earth applications.
