Thin layers or films of metal oxides are used as a semiconductor material of solar cells and they are coated with a sensitizer to achieve the high absorption of sunlight. Various dyes have been used as sensitizers in solar cells. Rylene monoimide derivatives are developed as photosensitizers for dye-sensitized solar cells and as photodetectors. The Rylene monoimide derivatives have very good quantum efficiencies, particularly in the NIR region of the absorption spectrum.

Isoindigo-based conjugated polymers, PII2T-C6 and PII2T-C8, with carbosilane side chains have been designed and synthesized for stretchable electronic applications. The carbosilane side chains offerred a simple synthetic pathway to evaluate long and branched side chains in high yields and were prepared with a six or eight linear spacer plus two hexyl or octyl chains after branching. The studied polymers showed a high charge carrier mobility of 8.06 cm2 V-1 s-1 with an on/off current ratio of 106 as probed using a top-contact transistor device with organized solid state molecular packing structures, as investigated through grazing-incidance X-ray diffreaction (GIXD) and atomic force microscopy (AFM) technique systematically. The studied polymers, more attractive, exhibited superior thin film ductility with a low tensile modulus in a range of 0.27-0.43 GPa owing to the branched carbosilane side chain, and their mobility was remained higher than 1 cm2 V-1 s-1 even under a 60% strain along parallel or perpendicular direction to the tensile strain. Such polymer films, in addition, can be simultaneously operated over 400 stretching/releasing cycles and maintained stable electrical properties, suggesting the newly designed materials possessed great potential for next-generation skin-inspired wearable electronic application with high charge carrier mobility, low tensile modulus, and stable device characteristics during stretching.

An expeditious approach to catalytic enantioselective total syntheses of crinine-type Amaryllidaceae alkaloids has been accomplished via a Pd-catalyzed enantioselective decarboxylative allylation of allylenol carbonates as a key step (up to 96% ee). Using this strategy, collective total syntheses of Amaryllidaceae alkaloids such as (-)-epi-elwesine (1b), (-)-crinine (1c), (-)-epi-crinine (1e), (-)-oxocrinine (1f), and (-)-buphanisine (1d) have been accomplished. Gratifyingly, naturally occurring Amaryllidaceae alkaloids such as (+)-vittatine (1g), (+)-epi-vittatine (1h), and (+)-epi-elwesine (1i) [enantiomers of (-)-1c, (-)-1e, and (-)-1b, respectively] have also been achieved by switching the antipode of ligand used in the catalytic enantioselective step.

Identifying the biological origin of a disease and the potential targets for intervention are some of the first steps in the discovery of a medicine. The metabotropic glutamate receptor 4 (mGlu4) has lately received much attention due to its potential role in various neuronal diseases such as Parkinson’s disease (PD) and other disorders. To better understand the role of mGlu4 in health and disease conditions, we were interested in developing an mGlu4-selective radiotracer for in vivo studies. Herein we discuss our efforts to develop novel mGlu4 positron emission tomography (PET) radiotracers from mGlu4 positive allosteric modulators (PAMs). We have investigated the biology of this receptor in vitro using cells expressing mGlu4, as well as in vivo, using the 6-hydroxydopamine (6-OHDA)-lesion rat model of Parkinson’s disease. Results of cell studies showed the important role of endogenous glutamate in inducing changes in the affinity of allosteric modulators of mGlus. Results from PET imaging studies showed the interplay between presynaptic mGlu4 and postsynaptic mGlu5 expression in the lesioned side of the brain, while the results of pharmacological MRI studies of the hemodynamic response showed enhanced signal changes in cortical areas in the lesioned side after challenge with mGlu4 PAMs or mGlu5 negative allosteric monitors (NAMs).
