This paper reports the self-assembly of two new tetrathiafulvalene (TTF) derivatives that contain one or two urethane groups. The formation of nanoribbons was evidenced by scanning electron microscopy (SEM) and X-ray diffraction (XRD), which showed that the self-assembly ability of T 1 was better than that of T 2 . The results revealed that more urethane groups in a molecule did not necessarily instigate self-assembly. UV-vis and FTIR spectra were measured to explore noncovalent interactions. The driving forces for self-assembly of TTF derivatives were mainly hydrogen bond interactions and π-π stacking interactions. The electronic conductivity of the T 1 and T 2 films was tested by a four-probe method.

Great efforts have been made in the last few decades to realize electronic devices based on organic molecules. A possible approach in this field is to exploit the chirality of organic molecules for the development of spintronic devices, an applicative way to implement the chiral-induced spin selectivity (CISS) effect. In this work we exploit enantiopure tetrathiafulvalene (TTF) derivatives as chiral inducers at the nanoscale.

Electron donor tetrathiafulvalene (TTF) and electron acceptor naphthalene diimide (NDI) derivatives were used to synthesize a 3D Zn-TTF/NDI-MOF. Multiple redox active sites and charge transfer endow the pristine MOF anode with excellent rate behavior and long term cycling performance (with an average specific capacity of 956 mA h g at 1 A g over 600 cycles). This study highlights the great potential of elaborately-designed MOFs for developing efficient anode materials.

Background: Pembrolizumab, an immune checkpoint inhibitor (ICI), shows significant survival benefits in patients with microsatellite instability-high (MSI-H) metastatic colorectal cancer (mCRC), but its efficacy in microsatellite-stable (MSS) mCRC is limited. Although ICIs are effective in tumor mutational burden-high (TMB-H) solid tumors, the impact on MSS-TMB-H mCRC, a rare subset within MSS mCRC, remains unclear.
Materials And Methods: We conducted a retrospective analysis using clinical and genomic data from the Center for Cancer Genomics and Advanced Therapeutics (C-CAT) repository in Japan.

Article Synopsis
- A study explored salvage chemotherapy using capecitabine plus oxaliplatin (XELOX) for gastric cancer patients who couldn't tolerate or were resistant to cisplatin, but it was halted due to low patient enrollment.
- 12 patients participated, revealing a disease control rate of 90% and a response rate of 30%, with median progression-free survival of 4.2 months and overall survival of 7.1 months.
- Common severe side effects included fatigue and low potassium levels, but there were no treatment-related deaths, suggesting XELOX might be beneficial for these patients.

In this work, we exploit the electronic features of tetrathiafulvalene (TTF) as a backbone in synthesizing chiral derivatives. The aim is to make use of TTF's well-known and unique redox and semiconducting properties in the fields of enantio-selective recognition and chiral charge transfer (CT) complex preparation, with the ultimate objective of obtaining devices with various potential applications, ranging from plasmonics to quantum computing. In particular, both cyclohexane-bis (TTF-amide)-based enantiomers 1-(S,S) and 1-(R,R), stable under an oxidation regime, have been selected, and under these conditions, the electrochemical enantiospecific response of the four possible systems, coming from the combination with L- and D-tartaric acid, respectively, was tested.
