We report the use of a phenylalkyl side chain modified donor molecule to increase the open-circuit voltage (Voc) of an organic photovoltaic device. The bulky side chain is able to alter the donor/acceptor interface without interfering in the molecular packing. As a result, both Voc and device performance are improved.

Distinct Fermi Resonance Patterns of Weak Coupling in 2D-IR Spectra of 5-Cyanoindole Revealed by Isotope Labeling.

Fermi resonance is a common phenomenon, and a hidden caveat exists in the applications of infrared probes, causing spectral complication and shorter vibrational lifetime. In this work, using the cyanotryptophan (CNTrp) side chain model compound 5-cyanoindole (CN-5CNI), we performed Fourier transform infrared spectroscopy (FTIR) and two-dimensional infrared (2D-IR) spectroscopy on unlabeled CN-5CNI and its isotopically labeled substituents (CN-5CNI, CN-5CNI, CN-5CNI) and demonstrated the existence of Fermi resonance in 5CNI. By constructing the Hamiltonian and simulating 2D-IR spectra, we show that the distinct Fermi resonance 2D-IR patterns in various isotope substituents are determined by the quantum mixing consequences at the = 1 state, as well as the = 2 state, where the Fermi coupling and anharmonicity play a crucial role.

Enhancing both ionic conductivity and mechanical robustness remains a major challenge in designing solid-state electrolytes for lithium batteries. This work presents a novel approach in designing mechanically robust and highly conductive solid-state electrolytes, which involves ionic liquid-based cross-linked polymer networks incorporating polymeric ionic liquids (PILs). First, linear PILs with different side groups were synthesized for optimizing the structure.

We are facing a shortage of new antibiotics to fight against increasingly resistant bacteria. As an alternative to conventional small molecule antibiotics, antimicrobial polymers (AMPs) have great potential. These polymers contain cationic and hydrophobic groups and disrupt bacterial cell membranes through a combination of electrostatic and hydrophobic interactions.

Neuropeptides are inter-cellular signaling molecules occurring throughout animals. Most neuropeptides bind and activate G-protein coupled receptors, but some also activate ionotropic receptors (or "ligand-gated ion channels"). This is exemplified by the tetra-peptide H-Phe-Met-Arg-Phe-NH (FMRFa), which activates mollusc and annelid FMRFa-gated sodium channels (FaNaCs) from the trimeric degenerin/epithelial sodium channel superfamily.
