Dynamic in-situ sensing of fluid-dispersed 2D materials integrated on microfluidic Si chip
(2017)In this work, we propose a novel approach for wafer-scale integration of 2D materials on CMOS photonic chip utilising methods of synthetic chemistry and microfluidics technology. We have successfully demonstrated that this ... -
Giant Optical Activity of Quantum Dots, Rods, and Disks with Screw Dislocations
(2015)For centuries mankind has been modifying the optical properties of materials: first, by elaborating the geometry and composition of structures made of materials found in nature, later by structuring the existing materials ... -
Photoluminescence of a quantum-dot molecule
(2015)The coherent coupling of quantum dots is a sensitive indicator of the energy and phase relaxation processes taking place in the nanostructure components. We formulate a theory of low-temperature, stationary photoluminescence ... -
Modulation of Protein Fouling and Interfacial Properties at Carbon Surfaces via Immobilization of Glycans Using Aryldiazonium Chemistry
(2016)Carbon materials and nanomaterials are of great interest for biological applications such as implantable devices and nanoparticle vectors, however, to realize their potential it is critical to control formation and composition ... -
Molecular devices based on reversible singlet oxygen binding in optical and photomedical applications.
(2016)Polycyclic aromatic hydrocarbons are known to bind singlet oxygen with formation of endoperoxides, which can be released upon heating. This process is now capturing broad attention due to its potential in photomedicine. ... -
Glycosidase activated release of fluorescent 1,8-naphthalimide probes for tumor cell imaging from glycosylated 'pro-probes'
(2016)Glycosylated 4-amino-1,8-naphthalimide derivatives possess a native glycosidic linkage that can be selectively hydrolysed in situ by glycosidase enzymes to release the naphthalimide as a fluorescent imaging or therapeutic ... -
The characterization of an intestine-like genomic signature maintained during Barrett's-associated adenocarcinogenesis reveals an NR5A2-mediated promotion of cancer cell survival
(2016)Barrett’s oesophagus (BO), an intestinal-type metaplasia (IM), typically arising in conjunction with gastro-oesophageal reflux disease, is a prominent risk factor for the development of oesophageal adenocarcinoma (OAC). ... -
Conformational and structural studies of meso monosubstituted metalloporphyrins - Edge-on molecular interactions of porphyrins in crystals
(2016)A series of meso monosubstituted metalloporphyrins were synthesized to assess the structural chemistry of porphyrins with only one substituent. The structures of four nickel(II) and zinc(II) complexes with either alkyl ... -
Crystal structure of 5-tert-butyl-10,15,20-triphenylporphyrin
(2016)In the title free base porphyrin, C42H34N4, the neighbouring N N distances in the center of the ring vary from 2.818 (8) to 2.998 (8) A ˚ and the phenyl rings are tilted from the 24-atom mean plane at angles varying ... -
Contribution of bacteriochlorophyll conformation to the distribution of site-energies in the FMO protein
(2016)The structural data for the Fenna-Matthews-Olson (FMO) protein indicate that the bacteriochlorophylls (BChls) display a significant degree of conformational heterogeneity of their peripheral substituents and the ... -

(2016)Den Trendbericht Organische Chemie haben 30 Autoren erstellt, deren Namen hinter den 24 Beiträgen stehen. Bernd F. Straub von der Universität Heidelberg koordinierte. -
A two-pronged attack on DNA: Targeting guanine quadruplexes with nonplanar porphyrins and DNA-binding small molecules
(2016)Cancer therapy requires the identification and selective targeting of cancer‐specific effectors. DNA is considered to be a chemotherapeutic target for cancer because of its involvement in cellular proliferation. In ... -
Current developments in using meso-(Tetra)substituted porphyrins for PDT
(World Scientific,, 2016)The goal of this chapter is to describe recent advances in the development and use of meso-tetrasubstituted porphyrins in photodynamic therapy (PDT). The focus is on analogues of 5,10,15,20- tetrakis(3-hydroxyphenyl)chlorin ... -
Studying the intersystem crossing rate and triplet quantum yield of meso-substituted porphyrins by means of pulse train fluorescence technique
(2016)Excited state dynamics, particularly intersystem crossing, of a set of meso-substituted porphyrins bearing different electron-donor and acceptor groups was studied by pulse train fluorescence technique. Triplet quantum ... -
Nucleophilic Aromatic Substitution on Pentafluorophenyl-Substituted Dipyrranes and Tetrapyrroles as a Route to Multifunctionalized Chromophores for Potential Application in Photodynamic Therapy
(2016)The application of porphyrinoids in biomedical fields like photodynamic therapy (PDT) requires the introduction of functional groups to adjust their solubility in the biological environment and to allow a coupling to ... -
Structural variation in cation-assisted assembly of high-nuclearity Mn arsonate and phosphonate wheels
(2016)Comproportionation reactions between MnCl2 and KMnO4 in the presence of arsonate or phosphonate ligands promote the cation-assisted assembly of high-nuclearity, wheel-shaped or toroidal {Mn8} (1) and {Mn24} (2) complexes; ... -
