(2018)Two series of amphiphilic meso-tetrasubstituted porphyrin conjugates based on 5,10,15,20-tetrakis(3-hydroxyphenyl)porphyrin (m-THPP) covalently linked to L-amino acids and heterocycles were synthesized efficiently in the ... -
Reaction of porphyrin-based surface-anchored metal?organic frameworks caused by prolonged illumination
(2018)Crystalline surface-anchored metal–organic framework (SURMOF) thin films made from porphyrin-based organic linkers have recently been used in both photon upconversion and photovoltaic applications. While these studies ... -
The good, the bad, and the ugly ? controlling singlet oxygen through design of photosensitizers and delivery systems for photodynamic therapy.
(2018)Singlet oxygen, although integral to photodynamic therapy, is notoriously uncontrollable, suffers from poor selectivity and has fast decomposition rates in biological media. Across the scientific community, there is a ... -
High content screening as high quality assay for biological evaluation of photosensitizers in vitro.
(2013)A novel single step assay approach to screen a library of photdynamic therapy (PDT) compounds was developed. Utilizing high content analysis (HCA) technologies several robust cellular parameters were identified, which can ... -
Cubane Cross-Coupling and Cubane-Porphyrin Arrays
(2018)Herein, an improved methodology for aryl‐cubane cross‐coupling is reported. The peculiarities of the cubane core and its behavior during cross‐coupling conditions were analyzed, while the versatility of this adapted Baran ... -
Nonplanar Porphyrins by N-Substitution: A Neglected Pathway
(2018)N‐substitution of porphyrins has been a neglected route towards nonplanar porphyrins for the past decades. Previously, they featured in a host of potential medicinal and biochemical applications. However, tailored syntheses ... -
Sensitive fluorescence on-off probes for the fast detection of a chemical warfare agent mimic
(2018)Two highly sensitive probes bearing a nucleophilic imine moiety have been utilized for the selective detection of chemical warfare agent (CWA) mimics. Diethyl chlorophosphate (DCP) was used as mimic CWAs. Both iminocouma ... -
Control of triplet state generation in heavy atom-free BODIPY-anthracene dyads by media polarity and structural factors
(2018)A family of heavy atom-free BODIPY–anthracene dyads (BADs) exhibiting triplet excited state formation from charge-transfer states is reported. Four types of BODIPY scaffolds, different in the alkyl substitution pattern, ... -
Water-soluble, neutral 3,5-diformyl-BODIPY with extended fluorescence lifetime in a self-healable chitosan hydrogel
(2017)3,5-Diformyl-4,4-difluoro-4-bora-3a,4a-diaza-s-indacene (3,5-diformyl-BODIPY) can be used as an efficient biofunctional cross-linker to generate a new class of chitosan-based hydrogels with fluorescence resonance energy ... -
Crystal structure and synthesis of 3-(1H-pyrrol-2-yl)-1-(thiophen-2-yl)propanone
(2018)The title compound, C11H9NOS, was obtained in an improved yield compared to previous literature methods. The molecule is essentially planar with a maximum deviation of 0.085 Å from the mean plane through all non-H atoms. ... -
Enhancing the photoluminescence of surface anchored metal?organic frameworks: mixed linkers and efficient acceptors
(2018)We present two approaches to enhance the photoluminescence quantum yield (PLQY) of surface-anchored metal–organic frameworks (SURMOFs). In the first approach we fabricate SURMOFs from a mix of an emissive linker with an ... -
Pre-/post-functionalization in dipyrrin metal complexes - antitumor and antibacterial activity of their glycosylated derivatives
(2018)A post-functionalization route to tris(dipyrrinato) metal complexes is presented giving access to a range of new complexes relevant in the context of medicinal inorganic chemistry. A pentafluorophenyl group in the meso-position ... -
BODIPY-Pyrene and Perylene Dyads as Heavy-Atom-Free Singlet Oxygen Sensitizer
(2018)Dyads combining BODIPY as an electron acceptor and pyrene or perylene as electron donor subunits were prepared and their photophysical properties were studied by steady‐state and transient spectroscopy. Depending on the ... -
Synthesis and Characterization of Temperature-Sensitive and Chemically Cross-Linked Poly( N-isopropylacrylamide)/Photosensitizer Hydrogels for Applications in Photodynamic Therapy
(2018)A novel poly(N-isopropylacrylamide) (PNIPAM) hydrogel containing different photosensitizers (protoporphyrin IX (PpIX), pheophorbide a (Pba), and protoporphyrin IX dimethyl ester (PpIX-DME)) has been synthesized with a ... -
Porphyrins in troubled times: a spotlight on porphyrins and their metal complexes for explosives testing and CBRN defense
(2018)Porphyrins are large π-aromatic systems that can complex metal ions from all across the periodic table. The resulting metalloporphyrins are readily tunable with regards to analyte detection properties, and constitute an ... -
Delayed release singlet oxygen sensitizers based on pyridone-appended porphyrins
(2017)A new type of porphyrin photosensitizer capable of generating singlet oxygen upon irradiation, storing it through binding to pyridone subunits, followed by slow release at 20‐40 °C is reported. The timescale of singlet ... -
