Summary: Here, we present the fabrication and characterization of ambipolar organic phototransistors (OPTRs) with sensing channel layers of a conjugated terpolymer, PDPP-8OBT-NDI. The OPTRs exhibited well-balanced ambipolar characteristics at a wide voltage range and showed high photosensitivity in the near-infrared (NIR) region. The devices also displayed stable and reproducible photocurrent responses under continuous NIR light illumination and optical on/off modulation.

Summary: Copolymerization of an electron-rich donor (D) unit with an electron-deficient acceptor (A) unit to construct efficient D-n-A-n type donors is an effective strategy for organic solar cell applications. In this work, a series of fused A units with different electron-deficient ability were constructed using benzo[2,1-b:3,4-b']dithiophene and benzopyrazine (BP), benzothiadiazole (BT), and benzoselenadiazole (BS). Three polymer donors were synthesized and their structure-performance relationships were systematically investigated. Among the three polymers, PBDP-BT showed the highest hole mobility. The device based on PBDP-BT:Y6 achieved an outstanding power conversion efficiency (PCE) of 15.14%, surpassing those based on PBDP-BP:Y6 and PBDP-BS:Y6.

Summary: Heteroleptic molybdenum complexes with P2N2 and non-innocent dithiolene ligands were synthesized and electrochemically characterized. The reduction potentials of the complexes were adjusted by ligand-ligand cooperativity via non-covalent interactions. This finding was supported by electrochemical studies, UV/Vis spectroscopy, and temperature-dependent NMR spectroscopy. The observed behavior resembles enzymatic redox modulation through second ligand sphere effects.

Summary: In this study, it was found that the DNA conductance increases by one order of magnitude upon drug intercalation due to the local unwinding of DNA base pairs adjacent to the intercalated sites. The research suggests that intercalators can be used to enhance or tune DNA conductance, opening up new possibilities for their potential applications in nanoelectronics.

Summary: In this study, a series of structurally distinct supramolecular assemblies of DPP based on Hamilton receptors (HRs) were designed and synthesized, which exhibited enhanced structural ordering and excitonic couplings through hydrogen bonding. The self-assembly mechanism was investigated using spectroscopy and solid-state IR spectroscopy. The morphology, photophysical and electrochemical properties of the self-assemblies were studied and compared with DPP molecular structures without HRs. The crystal structure analysis revealed slipped stack arrangements and intermolecular coupling between thiophene and lactam rings, leading to interesting optical properties.

Summary: The study investigates the fluorination of mirtazapine antidepressant drug using density functional theory calculations, finding that fluorine substitution influences intramolecular hydrogen bonding, charge transfers, stability, solubility, molecular polarity, and electronic spectra. The results show a red shift in electronic spectra of fluorinated derivatives and a negative Delta G value. Furthermore, fluorination increases the first hyperpolarizability of the drug, presenting an efficient strategy to enhance the nonlinear optical responses of antidepressant drugs.

Summary: This study investigates the band gap of hexagonal graphene quantum dots (GQDs) by adjusting and optimizing their band structure. The optical properties, such as absorption and emission spectra, are engineered through passivation with electron-withdrawing substituents. The results show that passivation with fluorine effectively decreases the band gap and induces a redshift in the absorption spectra. Additionally, the absorption spectra are found to be dependent on the size of GQDs and the type of passivating atoms (H or F).

Summary: The effects of thermal processing on the micro- and nanostructural features and relaxor-ferroelectric properties of a P(VDF-TrFE-CFE) terpolymer were investigated. Annealing reduces the Curie transition temperature and shifts the ferroelectric phase fraction, leading to relaxor-ferroelectric behavior. Changes in transition temperatures are related to alterations in hysteresis curves.

Summary: By adding DMSO in PEDOT:PSS solution and subjecting the films to DMSO vapor post-treatment, the electrical conductivity and Seebeck coefficient of poly(3,4-ethylenedioxythiophene): poly(styrenesulfonate) (PEDOT:PSS) films are optimized, leading to an enhancement in power factor. Through microscopical investigations and analysis of carrier concentration, it is confirmed that the improvements in thermoelectric performance are attributed to the enhancement of carrier mobility.
