摘要:
The invention relates to a photovoltaic coating containing a mixture of organic N-type (acceptor) and P-type (donor) semiconductor compounds, which makes it possible, when selecting the donor/acceptor pair, to modulate the semiconductor properties of the photovoltaic coating so as to enable the use thereof within a photovoltaic device, wherein one of the organic semiconductors includes a quinone core.
摘要:
The invention relates to a method for preparing, by means of transcarbonation, a compound of formula (I), including reacting a polyol of formula (II) with an alkyl carbonate or an alkylene carbonate in the presence of a catalytic system consisting of a catalytic entity selected from among the rare earth oxides or the mixtures thereof, and optionally an inert substrate.
摘要:
The present invention relates to a process for preparing dicarboxylic acids, in particular adipic acid (1,6-hexanedioic acid), through the action of nitric acid, from cyclic alcohols or ketones with a corresponding number of carbon atoms, in the presence of one or more nitrogen oxides in a molar concentration in the reaction medium of greater than 2.5 mmol per kg of reaction medium.
摘要:
The invention relates to a method for producing a compound of formula (I), comprising the reaction, in the presence of a catalytic system comprising a single rare earth oxide or a mixture of rare earth oxides, of an alkyl carbonate or an alkylene carbonate with a polyol of formula (II), wherein p is a whole number between 2 and 10.
