The versatile nature of organic conjugated materials renders their flawless integration into a diverse family optoelectronic devices with light-harvesting, photodetection, or light-emitting capabilities. Classes that offer the possibilities two more distinct functions are particularly attractive as they enable smart applications while providing benefits ease fabrication using low-cost processes...
There is a significant risk of severe graft-versus-host disease (GVHD) and graft failure after unrelated umbilical cord blood transplantation (CBT) if donor-recipient pairs are mismatched at major histocompatibility complex (MHC) loci. To mitigate these risks after MHC-mismatched CBT, we infused psoralen-treated, photochemically inactivated, mature donor T-lymphocytes with MHC (H2-haplotype) mi...
BACKGROUND Conflicting data have been reported about the effect of Toxoplasma serostatus on mortality after heart transplantation. Either a positive or a negative recipient Toxoplasma serostatus was found to be associated with increased mortality. METHODS We evaluated the effects of T. gondii infection on survival of our 582 cardiac allograft recipients operated upon between June 1984 and Jul...
A series of four donor aryl alkynyl substituted thiazole derivatives 3a-d and three similar aryl donor-acceptor systems 6a-c have been synthesized. All compounds bear different electron-donating groups in the 5-position of the thiazole core. The influence of both electron donor strength and the additional phenylethynyl unit on photophysical properties, i.e. UV/Vis absorption, fluorescence emiss...

Regio- and conformational isomerization are fundamental in chemistry, with profound effects upon physical properties, however their role in excited state properties is less developed. Here two regioisomers of bis(10H-phenothiazin-10-yl)dibenzo[b,d]thiophene-S,S-dioxide, a donor-acceptor-donor (D-A-D) thermally-activated delayed fluorescence (TADF) emitter, are studied. 2,8-bis(10H-phenothiazin-...
In contrast to conventional pyrene-based emitters which feature D-?-A type structures, a new class of possessing short axis are gaining interest owing both their academic importance and promising applications in organic optoelectronic materials. Herein, donor acceptor substituents were introduced at 1-, 3-positions by employing two step bromination reaction. Two 1-donor-3-acceptor pyrenes syste...
