A new side-chain C60-fullerene functionalized thiophene copolymer bearing tributylphosphine-substituted hexylic lateral groups was successfully synthesized by means of a fast and effective post-polymerization reaction on a regioregular ω-alkylbrominated polymeric precursor. The growth of the polymeric intermediate was followed by NMR spectrometry in order to determine the most convenient reaction time. The obtained copolymer was soluble in water and polar solvents and was used as a photoactive layer in single-material organic photovoltaic (OPV) solar cells. The copolymer photovoltaic efficiency was compared with that of an OPV cell containing a water-soluble polythiophenic homopolymer, functionalized with the same tributylphosphine-substituted hexylic side chains, in a blend with a water-soluble C60-fullerene derivative The use of a water-soluble double-cable copolymer made it possible to enhance the control on the nanomorphol. of the active blend, thus reducing phase-segregation phenomena, as well as the macroscale separation between the electron acceptor and donor components. Indeed, the power conversion efficiency of OPV cells based on a single material was higher than that obtained with the classical architecture, involving the presence of two distinct ED and EA materials (PCE: 3.11% vs. 2.29%, resp.). Moreover, the synthetic procedure adopted to obtain single material-based cells is more straightforward and easier than that used for the preparation of the homopolymer-based BHJ solar cell, thus making it possible to completely avoid the long synthetic pathway which is required to prepare water-soluble fullerene derivatives In the part of experimental materials, we found many familiar compounds, such as 2-Aminopropane-1,3-diol(cas: 534-03-2Electric Literature of C3H9NO2)
2-Aminopropane-1,3-diol(cas: 534-03-2) belongs to anime. Hydrogen peroxide (H2O2) and peroxy acids generally add an oxygen atom to the nitrogen of amines. With primary amines, this step is normally followed by further oxidation, leading to nitroso compounds, RNO, or nitro compounds, RNO2. Secondary amines are converted to hydroxylamines, R2NOH, and tertiary amines to amine oxides, R3NO.Electric Literature of C3H9NO2
