Generating electricity from raindrops efficiently has gone one step further. A research team led by scientists from the City University of Hong Kong (CityU) has recently developed a droplet-based electricity generator (DEG), featured with a field-effect transistor (FET)-like structure that allows for high energy-conversion efficiency and instantaneous power density increased by thousands times compared to its counterparts without FET-like structure. This would help to advance scientific research of water energy generation and tackle the energy crisis.

Pyrrole- and Azulene-Fused Azacoronene Dication with 22π+6π Aromatic Rings
17 Oct 2019
Polycyclic heteroaromatic molecules are a highly useful class of organic materials. In this study, synthesis of a new azacoronene, in which both pyrrole and azulene moieties are circularly fused, was achieved in just three steps. This new azacoronene exhibited multistep reversible oxidations under electrochemical and chemical conditions. Formation of an aromatic 22π-electron conjugation and a tropylium cation (6π-electron conjugation) in the dicationic state played a key role in stabilizing this cationic species.

A new type of photoconduction in a molecular crystal
29 Aug 2019
A highly conducting state has been found in a molecular crystal under UV-irradiation. The state reversibly appears in accordance with UV-irradiation, but does not appear by any other method such as raising the temperature, which often induces metallic behavior in insulating molecular crystals. The UV-excited state exhibits conduction and magnetic behavior characteristic of metallic substances. The result suggests that there is an optically accessible, but thermally inaccessible, state of matter.
