      A red-emitting Eu metal-organic framework (EuMOF) is successfully obtained by S.-Y. Song, H.-J. Zhang, and co-workers and serves as a multi-responsive luminescent sensor toward different organic molecules and inorganic ions. On page 4034, the red emission signal is changed after exposing the EuMOF to the analytes under UV light excitation: some of them even quench the luminescence. This work paves the way for the practical application of luminescent MOF sensors for pollutant detection.

      Nanohybrid heterojunction (NH-HJ) solar cells are developed on page 4042 by M. A. El Khakani and co-workers using pulsed laser deposition (PLD) to decorate TiO2 nanorods and single carbon nanotubes with PbS nanoparticles, and to integrate the formed nanohybrids directly into photovoltaic devices. This approach offers the latitude to achieve the direct assembly of different nanomaterials, thereby forming novel nanohybrids. By optimizing the size of the particles and tube lengths, NH-HJ solar cells exhibiting power conversion efficiencies as high as 5.3% are achieved.

      On page 4051, S. J. Zeng, H. R. Liu, J. H. Hao, and co-workers report an Mn2+ doping strategy for a new type of multifunctional upconversion nanoprobe based on a NaLnF4:Yb/Er system with controlled phase/size, tunable multi-color output, and dominant red upconversion emission. The nanoprobe can be used for multi-modal upconversion luminescence and X-ray bioimaging with deep tissue penetration. Most importantly, the blood vessels of the lung can be visualized, which promises faster and more accurate prognosis of pulmonary vascular diseases.

      Robert Dorresteijn, Nils Billecke, Mischa Schwendy, Sabine Pütz, Mischa Bonn, Sapun H. Parekh, Markus Klapper and Klaus Müllen

      Article first published online: 8 JUL 2014 | DOI: 10.1002/adfm.201470171

      In tumor cells, enzyme-triggered drug release from a nanoparticle after polymer cleavage is demonstrated by S. H. Parekh, M. Klapper, and co-workers on page 4026. The polymers within the particles contain a specific peptide sequence which is recognized and subsequently cleaved by matrix-metalloproteinase-2, an enzyme overexpressed in tumor tissues. The higher mobility of polymer fragments finally leads to drug release and associated cytotoxicity.

      Triblock copolymer nanoparticle with tunable drug release. Nanocarriers based on PLLA-b-peptide-b-PLLA copolymers are proved to have exceptional material properties for controlled drug release in response to MMP-2-dependent peptide cleavage. Comparison specimens demonstrate the tunable bioactivity of these nanocarriers based on polymer constitution. As MMP-2 is selectively overexpressed in tumor tissues, this is a promising system for solid tumor cancer therapy.

      Splitting excitons into free charges can be very efficient at polymer/fullerene interfaces but it becomes a challenging task when the fullerene is replaced by a polymeric acceptor. Here, the structural origin of the photocurrent generation in P3HT:P(NDI2OD-T2) all-polymer solar cells is investigated. A proper relative orientation of the polymer crystallites is needed to create free charge carriers.

      Size dependent resistive switching is demonstrated across nanoscale metal-SrTiO3 interfaces ranging from 20 to 200 nm. The size dependent resistance of the high resistance state results from changes in both the interfacial area and Schottky barrier. The low resistant state exhibits size independent resistances due to the dominant fast conductive path induced by electroforming.
