The fabricated OFET devices with one of the derivatives exihibited typical p-type behavior under ambient conditions. Incorporation of azulene into linearly π-extended polycyclic aromatic hydrocarbons results in a narrow HOMO–LUMO gap and high stability toward air uder visible light. X-ray analysis revealed a herringbone packing structure of the azulene–fused pentacycle based on the balance of CH–π and π–π interactions.

The dynamic activity of molecules is the essence of living phenomena. Toward the analysis of this, the establishment of in vivo molecular imaging techniques has been sought. Hyperpolarized nuclear magnetic resonance (NMR) is a promising technique that enables in vivo molecular imaging using highly sensitive hyperpolarized NMR molecular probes and is expected to be a next-generation molecular imaging technology. However, a major challenge lies in the rapid relaxation of the hyperpolarized nuclear spin state of the molecule, i.e., a short lifetime of high sensitivity. We have made our efforts to address this critical issue. This award account mainly describes our research to develop hyperpolarized molecular probes with long hyperpolarization lifetime. Based on the understanding of the relaxation mechanism of hyperpolarized spin states, we successfully developed various hyperpolarized 13C molecular probes, some of which were applied for in vivo studies. In addition, we demonstrated the development of hyperpolarized 15N molecular probes with remarkably long hyperpolarization lifetimes. These results pave the way for the rational design of hyperpolarized molecular probes, which has been difficult to achieve so far.

It was first artificially made by us in 2011. Since then, anomalies of water molecules free from any hydrogen-bonding have been discovered in succession. In this account, we summarize the research progress in the past decade from the aspect of synthesis, derivatization, and reactivity of fullerenes with water inside as well as their quantum and classical dynamics. A single water molecule trapped within fullerene cages has been found to modulate the chemical and physical nature of exohedral cages as well as to exhibit anomalous quantum spin conversion. In this account, we discuss the synthesis, modulated exohedral properties, ortho–para conversion, and classical dynamics of water in fullerenes.","PeriodicalId":9511,"journal":{"name":"Bulletin of the Chemical Society of Japan","volume":"357 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135486514","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
