Abstract: The present disclosure relates to a novel polymer compound and a method for preparing the same. More particularly, the present disclosure relates to a novel conductive low band gap electron donor polymer compound having high photon absorptivity and improved hole mobility, a method for preparing the same and an organic photovoltaic cell containing the same. Since the conductive polymer compound as a low band gap electron donor exhibits high photon absorptivity and superior hole mobility, it can be usefully used as a material for an organic optoelectronic device such as an organic photodiode (OPD), an organic thin-film transistor (OTFT), an organic light-emitting diode (OLED), an organic photovoltaic cell, etc. as well as in the development of a n-type material.

Abstract: Disclosed is a zinc-imidazole complex mixed catalyst. Also disclosed are a method for preparing the zinc-imidazole complex mixed catalyst and a method for producing a methyl N-phenyl carbamate in high yield with high selectivity in the presence of the catalyst. The zinc-imidazole complex mixed catalyst can be reused due to its high reaction stability. In addition, the use of the zinc-imidazole complex mixed catalyst leads to a marked improvement in the production yield of a methyl N-phenyl carbamate with high selectivity.

Abstract: The present disclosure relates to a method for separating sugars and acids with reduced energy consumption, including a step of diffusively dialyzing a first acid hydrolysate obtained by saccharifying biomass with an acid solution, thereby preparing a second acid hydrolysate wherein the concentration of the acid solution contained in the acid hydrolysate is decreased; and a step of electrolyzing the second acid hydrolysate, thereby separating sugars from the acid solution, which is advantageous in that less energy is consumed, the separated acid solution can be recycled directly without further treatment due to high concentration and loss of sugars can be minimized.
