The dielec. constant (εr) of organic semiconductors is a key material parameter for improving device performance in the field of organic electronics. However, the effect of the dielec. constant on the electronic and optoelectronic properties of materials remains unclear due to the scarcity of known organic semiconductors with an εr value higher than 6. Herein, the optical and electronic properties of a homologous series of fullerene derivatives with high εr are studied. The low frequency (<106 Hz) εr is extracted from the capacitance measured using impedance spectroscopy, and the effect of length (n) and geometrical arrangement of the polar ethylene glycol (EG) side chains is investigated. The εr is found to correlate with length for the sym. Bingel adducts, whereas for the unsym. branched-EG chain adducts there is no significant difference between the two EG chain lengths. For BTrEG-2, the εr reaches 10, which is an unprecedented value in monoadduct fullerene derivatives These materials open up new possibilities of studying the effect of εr in organic electronic devices such as organic photovoltaics, organic thermoelecs., and organic field-effect transistors. Journal of Physical Chemistry C published new progress about Bingel reaction. 23783-42-8 belongs to class ethers-buliding-blocks, name is 2,5,8,11-Tetraoxatridecan-13-ol, and the molecular formula is C9H20O5, Recommanded Product: 2,5,8,11-Tetraoxatridecan-13-ol.
