Enforcing Extended Porphyrin J-Aggregate Stacking in Covalent Organic Frameworks.

J Am Chem Soc 2018 Nov 19. Epub 2018 Nov 19.

Department of Chemistry and Center for NanoScience (CeNS) , University of Munich (LMU) , Butenandtstrasse 5-13 , 81377 Munich , Germany.

The potential of covalent organic frameworks (COFs) for realizing porous, crystalline networks with tailored combinations of functional building blocks has attracted considerable scientific interest in the fields of gas storage, photocatalysis, and optoelectronics. Porphyrins are widely studied in biology and chemistry and constitute promising building blocks in the field of electroactive materials, but they reveal challenges regarding crystalline packing when introduced into COF structures due to their nonplanar configuration and strong electrostatic interactions between the heterocyclic porphyrin centers. A series of porphyrin-containing imine-linked COFs with linear bridges derived from terephthalaldehyde, 2,5-dimethoxybenzene-1,4-dicarboxaldehyde, 4,4'-biphenyldicarboxaldehyde and thieno[3,2- b]thiophene-2,5-dicarboxaldehyde, were synthesized, and their structural and optical properties were examined.

Femtosecond laser induced Coulomb explosion imaging of aligned OCS oligomers inside helium nanodroplets.

J Chem Phys 2018 Oct;149(15):154306

Department of Chemistry, Aarhus University, Langelandsgade 140, 8000 Aarhus C, Denmark.

Dimers and trimers of carbonyl sulfide (OCS) molecules embedded in helium nanodroplets are aligned by a linearly polarized 160 ps long moderately intense laser pulse and Coulomb exploded with an intense 40 fs long probe pulse in order to determine their structures. For the dimer, recording of 2D images of OCS and S ions and covariance analysis of the emission directions of the ions allow us to conclude that the structure is a slipped-parallel shape similar to the structure found for gas phase dimers. For the trimer, the OCS ion images and the corresponding covariance maps reveal the presence of a barrel-shaped structure (as in the gas phase) but also other structures not present in the gas phase, most notably a linear chain structure.

Hydrogen-bonded perylene bisimide J-aggregate aqua material.

Chem Sci 2018 Sep 30;9(34):6904-6911. Epub 2018 Jul 30.

Universität Würzburg , Institut für Organische Chemie , Am Hubland , 97074 Würzburg , Germany . Email:

A new twelvefold methoxy-triethyleneglycol-jacketed tetraphenoxy-perylene bisimide () amphiphile was synthesized that self-assembles into two types of supramolecular aggregates in water: red-coloured aggregates of low order and with weak exciton coupling among the PBIs and blue-coloured strongly coupled J-aggregates consisting of a highly ordered hydrogen-bonded triple helix of PBIs. At room temperature this PBI is miscible with water at any proportions which enables the development of robust dye aggregates in solution, in hydrogel states and in lyotropic liquid crystalline states. In the presence of 60-95 wt% water, self-standing coloured hydrogels exhibit colour changes from red to blue accompanied by a fluorescence light-up in the far-red region upon heating in the range of 30-50 °C.

Slipped Capital Femoral Epiphysis: A Review for Pediatricians.

Pediatr Ann 2018 Sep;47(9):e377-e380

Slipped capital femoral epiphysis (SCFE) is one of the most common hip pathologies that occurs during adolescence, and its incidence has been increasing over the past decades. For this reason, pediatricians should be aware of this entity to ensure an early diagnosis and intervene in a timely manner. The typical patient with SCFE is an adolescent who is obese presenting with hip pain, but it can also occur in children who are not obese; therefore, SCFE should be part of the differential diagnosis in any skeletally immature patient presenting with hip or knee pain.

Intermolecular Packing Effects on Singlet Fission in Oligorylene Dimers.

ACS Omega 2017 Aug 29;2(8):5095-5103. Epub 2017 Aug 29.

Department of Materials Engineering Science, Graduate School of Engineering Science and Center for Spintronics Research Network (CSRN), Graduate School of Engineering Science, Osaka University, Toyonaka, Osaka 560-8531, Japan.

Using the density functional theory method, the crystalline packing effect on the singlet fission (SF) rate of oligorylenes, some of which are found to exhibit SF in crystal forms, is revealed by evaluating the effective electronic coupling (||), the square of which is proportional to the SF rate. The || values for terrylene and quaterrylene dimer models are investigated for a variety of slip-stacked forms. It is found that these values show similar dependences on the intermolecular packing as a function of lateral and longitudinal displacements of monomer frameworks, and that they are maximized in several configurations of one monomer slipped from another along the longitudinal axis.

Traumatic Penetrating Neck Injury with Right Common Carotid Artery Dissection and Stenosis Effectively Managed with Stenting: A Case Report and Review of the Literature.

Case Rep Vasc Med 2018 10;2018:4602743. Epub 2018 Jun 10.

Department of Neurosurgery, West China Hospital, Sichuan University, 37 Guo Xue Xiang Road, Chengdu, Sichuan 610041, China.

Introduction: Penetrating neck injuries (PNI) are common and associated with arterial and other neuronal injuries. Although many authors have written on penetrating and blunt carotid artery injuries as a result of PNI or traumatic neck injuries, no one has reported a case or case series on PNI that resulted in blunt carotid dissection and stenosis.

Case Presentation: We present a case of 40-year-old building and construction male worker who slipped and fell on an iron rod that resulted in penetrating wound on the right side of the anterior neck a week prior to presenting at our facility. Read More

Self-assembly of multi-stranded perylene dye J-aggregates in columnar liquid-crystalline phases.

Nat Commun 2018 07 6;9(1):2646. Epub 2018 Jul 6.

Institut für Organische Chemie, Universität Würzburg, Am Hubland, 97074, Würzburg, Germany.

Many discoid dyes self-assemble into columnar liquid-crystalline (LC) phases with packing arrangements that are undesired for photonic applications due to H-type exciton coupling. Here, we report a series of crystalline and LC perylene bisimides (PBIs) self-assembling into single or multi-stranded (two, three, and four strands) aggregates with predominant J-type exciton coupling. These differences in the supramolecular packing and optical properties are achieved by molecular design variations of tetra-bay phenoxy-dendronized PBIs with two N-H groups at the imide positions.

National Databases in Pediatric Orthopaedic Surgery: A Comparison of Demographics, Procedures, and Outcomes.

J Pediatr Orthop 2018 Jul 2. Epub 2018 Jul 2.

Children's of Alabama, Department of Orthopaedic Surgery, University of Alabama at Birmingham, Birmingham, AL.

Background: Large national databases have been increasingly used in recent years to determine the rate of adverse events and identify factors associated with altered surgical outcomes. This can be especially useful to evaluate rare events such as 30-day mortality. Despite differences between national pediatric databases, there have been no comparison studies in the pediatric orthopaedic population. Read More

Visualization of nonemissive triplet species of Zn(ii) porphyrins through Cu(ii) porphyrin emission via the reservoir mechanism in a porphyrin macroring.

Photochem Photobiol Sci 2018 Jul;17(7):883-888

Graduate School of Chemical Sciences and Technology, Tokyo University of Science, 1-3 Kagurazaka, Shinjuku-ku, Tokyo 162-8601, Japan.

A macroring composed of three Cu(ii) porphyrins (CuP) and three slipped-cofacial Zn(ii) porphyrin (ZnP2) dimers exhibited near-IR emission from the CuP part. The emission lifetime of the macroring (15 μs) was 500 times longer compared to that of a Cu porphyrin monomer (e.g. Read More
