Four high triplet organic semi-conductors based on the donor-spiro-acceptor design (D-spiro-A) have been synthesized. Their physicochemical and photophysical properties have been studied, compared and discussed in light of the nature of their respective donor/acceptor units. The four compounds have been used as host materials in efficient sky-blue (EQE > 10% at 10 mA cm-2) phosphorescent organic light emitting diodes.

Selective single arylsulfanylation reactions of aryl diiodides with aryl or hetaryl thiols to give a broad array of iodine-functionalized sulfides were developed. Further elaboration of the iodine-containing products to provide a variety of aryl and hetaryl sulfides through coupling reactions was also demonstrated. Georg Thieme Verlag Stuttgart, New York.

The application of a general synthetic approach to prepare molecular chains is reported. It is based on a step-by-step method each consisting first in a Pd-catalyzed reaction between ArI and HXAr′Br (Ar=aryl, Ar′=arylene) to give ArXAr′Br followed by a Cu
Preparation of functionalized aryl magnesium reagents by the addition of magnesium aryl thiolates and amides to arynes
Lin, Wenwei,Sapountzis, Ioannis,Knochel, Paul
, p. 4258 - 4261 (2007/10/03)
(Chemical Equation Presented) Reactive arynes, which are readily generated by the reaction of ortho-iocloarylsulfonates with iPrMgCl, undergo the smooth addition of various magnesium nucleophiles like magnesium thiolates, selenides, and amides. In all cases the resulting functionalized aryl magnesium species can be trapped by an electrophile leading to highly functionalized aromatic compounds (see scheme).
Aromatic nucleophilic polysubstitution by sequential SRN1 reactions
Beugelmans, Rene,Chbani, Mohamed
, p. 290 - 305 (2007/10/02)
Substitution of aromatics (benzene, naphthalene and pyridine) by two or three distinct nucleophiles derived from phosphonates and/or thiolates can be performed by sequential photosimulated SRN1 reactions whose radical chain mechanism is compatible with the successively introduced substituents. aromatic polysubstitution / SRN1 mechanism / disubstituted aromatic / trisubstituted aromatic / distinct substituent
