Neoadjuvant chemotherapy is increasingly used in breast cancer, especially for downstaging the primary tumor in the breast and the metastatic axillary lymph node. Accurate evaluations of the response to neoadjuvant chemotherapy provide important information on the impact of systemic therapies on breast cancer biology, prognosis, and guidance for further therapy. Moreover, pathologic complete response is a validated and valuable surrogate prognostic factor of survival after therapy. Evaluations of neoadjuvant chemotherapy response are very important in clinical work and basic research. In this review, we will elaborate on evaluations of the efficacy of neoadjuvant chemotherapy in breast cancer and provide a clinical evaluation procedure for neoadjuvant chemotherapy.

“…Final proof for the structure of 2 was obtained by X‐ray diffraction analysis of single crystals of 2 a , obtained by slow evaporation of concentrated CH 2 Cl 2 solution. Comparing the crystal structure of 2 a with that reported earlier for 1 a 8a reveals some striking differences in the three‐dimensional structure of the compounds. Upon oxidation, the bond between C5 and C6 (Figure 1) decreases in order from a double bond with a normal bond length of 1.362 Å to a relatively long C sp2 C sp2 single bond (1.505(8) Å) in 2 a .…”

A 2e(-) /2H(+) redox platform has been implemented in the ethenyl-bridged bisphosphol-3-ol 1 to afford the first phospholes that feature chemically reversible oxidations. Oxidation of the title compounds to the corresponding bisphosphol-3-one 2 leads to a change in conjugation topology and a concomitant hypsochromic shift of the lowest-energy absorption maximum by 100 nm. Electrochemical oxidation proceeds without any detectable intermediates, whereas the deprotonated form of 1 can be observed in an aprotic medium during the reduction of 2. This dianionic intermediate 3 is characterized by end absorptions that are bathochromically shifted by circa 200 nm compared to those of 2.

“…Besides the common alkyl tether, other alkyne linkers, for example, thioethers, have been used, revealing substantial impact on the optical properties . Despite the versatility of these very general approaches, some fascinating derivatives have been obtained using other routes, such as radical reactions, cascade reactions, or carboboration followed by rearrangements . The creativity of chemists is seemingly endless, combining phosphole building blocks with or into larger architectures forming hybrid porphyrins and carbaboranes in order to create unprecedented properties.…”

This Minireview describes recent advances of organophosphorus compounds as opto-electronic materials in the field of organic electronics. The progress of (hetero-) phospholes, unsaturated phosphanes, and trivalent and pentavalent phosphanes since 2010 is covered. The described applications of organophosphorus materials range from single molecule sensors, field effect transistors, organic light emitting diodes, to polymeric materials for organic photovoltaic applications.
