“…However, their absorptions in thin films, especially when mixed with an electron acceptor such as [6,6]-phenyl-C61-butyric acid methyl ester (PC61BM), the nanostructuration in bulk heterojunctions have still to be examined. [79][80][81] Parallel to this, panchromatic dyes are also actively researched for photopolymerization applications. In this field, PP6, D9 and D10 by their broad absorption spectra extending over the visible range are perfect candidates and polymerization tests for the free radical polymerization of acrylates or the cationic polymerization of epoxides under low light intensity and even for sunlight-induced polymerization will be reported in forthcoming works.…”

A series of twelve dyes based on the 4,4-bis(4-methoxyphenyl)butadienyl donor and differing by the electron acceptors have been designed and synthesized. The different dyes were characterized by UV-visible absorption spectroscopy as well as cyclic voltammetry. By fine tuning the electron-accepting ability of the fourteen selected acceptors, dyes absorbing between 400 and 650 nm could be obtained with this π-extended donor. To get a deeper insight into the optical properties, solvatochromism was investigated in 23 different solvents and remarkable linear correlations could be obtained using the Taft and Catalan solvatochromism scales. A comparison with four dyes used as reference compounds and differing from the series of twelve dyes by the structure of the electron-donating groups was also established so that the electron releasing ability of the 4,4-bis(4-methoxyphenyl)butadienyl donor could be compared with the reference ones. To prepare these four references compounds, only two electron acceptors previously used for the design of the twelve dyes have been employed. Interestingly, variation of the absorption maxima of the twelve dyes was determined as being more influenced by the polarizability of the solvent rather than by its polarity. To support the experimental results, theoretical calculations were carried out.

The selection of electron donors and nonfullerene acceptors (NFAs) in organic solar cells (OSCs) is crucial for improving photovoltaic performance. Machine learning (ML) has brought a breakthrough solution. Herein, 292 donor‐NFA pairs with experimental OSC parameters from the reported articles are collected. The ML descriptors include device processing parameters, molecular properties, and molecular structure. The five ML regression models, random forest (RF), extra tree regression, gradient boosting regression tree, adaptive boosting, and artificial neural network (ANN) are trained. GridSearchCV is used for hyperparameter optimization of ML regression models. The SHapley Additive exPlanation approach is employed to analyze descriptor importance. Among the trained five ML models, the RF model shows superior performance, achieving Pearson's correlation coefficient (r) of 0.81 on the test set. Based on the donors and NFAs in constructed dataset, the 9779 donor–NFA pairs for OSCs are generated by randomly combining donor and acceptor molecules. The trained RF model is utilized to predict the power conversion efficiency (PCE) of new donor–acceptor pairs for OSCs. The results indicate that the OSC composed of PBDB‐TF as donor and L8‐BO as acceptor can achieve the remarkable PCE of 17.9%.
