A Deep‐Red‐Absorbing Osmium(II) Complex as a Photosensitizer for Photodynamic Therapy Inducing Immunogenic Cell Death

open access: yesAngewandte Chemie, EarlyView.
A deep‐red‐excited osmium(II) photosensitizer (Os2) induces immunogenic cell death (ICD) under 740 nm irradiation and triggers robust anti‐tumor immune responses both in vitro and in vivo. ABSTRACT Immunogenic cell death (ICD), which converts tumor cells into their own vaccine, plays a pivotal role in the development of novel anticancer therapies. Here,

Grid representations and the chromatic number

open access: yesComputational Geometry, 2013
A grid drawing of a graph maps vertices to grid points and edges to line segments that avoid grid points representing other vertices. We show that there is a number of grid points that some line segment of an arbitrary grid drawing must intersect. This number is closely connected to the chromatic number.

Spiro‑Linked Double Tetraphenylethenes: Solid‐State Emission and Circularly Polarized Luminescence Imaging

open access: yesAngewandte Chemie, EarlyView.
Two spirobisanthracene‐tetraphenylethene (SBA‐TPE) hybrid compounds are synthesized and their photophysical properties in the solid state reported. Circularly polarized luminescence in aggregates, films and dispersions is evaluated. Circularly polarized luminescence imaging is evaluated over crystals revealing discrimination of different types of ...

Color‐Pure Organic Luminophores: Characteristics, Definitions, Physical Basis and Fundamental Design Principles

open access: yesAngewandte Chemie, EarlyView.
Color‐pure all‐organic emitters, i.e., with narrow spectral characteristics, are intensively studied for high‐definition organic LEDs and multi‐color bioimaging. In order to guide targeted materials design, this educative review discusses spectral characteristics, proper definitions and units, and the physical basis of spectral broadening, to distill ...

Dicromatic number and fractional chromatic number

open access: yes, 2014
Given an undirected graph G, the chromatic number χ(G) is the minimum number of partitions of V(G) into independent sets. Given a directed graph D, a vertex set is acyclic if it does not contain a directed cycle.

On the cost-chromatic number of graphs

open access: yes, 1997
We consider vertex colorings in which each color has an associated cost, incurred each time the color is assigned to a vertex. For a given set of costs, a minimum-cost coloring is a vertex coloring which makes the total cost of coloring the graph as ...
