A cured matter obtained by polymerizing and curing a polymerizable composition comprising a compound having at least one episulfide in a molecule is reduced in an odor by adding a perfume to the polymerizable composition comprising the compound having at least one episulfide in a molecule.
A cloudiness of the lens is removed by raising a purity of sulfur to 98% or more.
A reduction in a chlorine content of the sulfur compound described above to 0.1% by weight or less elevates an oxidation resistance and a light fastness of the high refractive index optical material and improves a color tone thereof.
An optical product having a high refractive index and a high-degree transparency is provided by subjecting the composition in advance to deaerating treatment at 0 to 100° C. for one minute to 24 hours under a reduced pressure of 0.001 to 50 torr.

Through the strategy of cyclohexane-1, 4-dione embedded into thieno [3, 4-b] thiophene unit, a highly electron-deficient core (TTDO) is synthesized and the corresponding donor polymer (PBTT-F) is also been developed. The nonfullerene photovoltaic device based on this new donor polymer exhibited an outstanding PCE of 16.1%with a very high fill factor of 77.1%, which demonstrate it a very promising donor for high performance solar cells.

Three new solution-processable tetrabutylanthradithiophene (TBADT)-based organic semiconductors bearing two phenylethynyl, thiophen-2-ylethynyl, and thieno[3,2-b]thiophen-5-ylethynyl substituents have been synthesized and their thermal, optical, and electrochemical properties have been characterized. Preliminary tests of these compounds via drop-casting for thin-film transistors showed p-channel TFT transport with hole mobilities as high as 1.510-³ cm²/Vs and with a current on/off ratio of 104.
