- Compound for organic light-emitting device packaging and preparation method and application thereof
-
The invention discloses a compound for organic light-emitting device packaging and a preparation method and application thereof, and belongs to the technical field of organic light-emitting device thin film packaging. Meanwhile, the invention further provides a composition prepared from one or more of a compound L, an allyl compound, a photopolymerization initiator and a free radical polymerization initiator, and when the composition is applied to organic light-emitting device packaging, a packaging film can show low transmittance of oxygen and moisture, the service life of an organiclight-emitting device is prolonged, and a packaging composition of an organic/inorganic mixed packaging film, the packaging thin film, and a display device using the same with higher flatness are obtained by enhancing the etching resistance of an organic layer to plasma.

- A Highly Effective Route to Si?O?Si Moieties through O-Silylation of Silanols and Polyhedral Oligomeric Silsesquioxane Silanols with Disilazanes
-
A simple and highly practical catalyst-free O-silylation of silanols with commercially available disilazanes has been developed under mild conditions. In the case of polyhedral oligomeric silsesquioxane (POSS) silanols and some other silanols, it was necessary to use catalytic amounts of inexpensive Bi(OTf)3 as additional catalyst. This efficient chlorine-free protocol involves the synthesis of a wide range of important organosilicon derivatives such as unsymmetrical disiloxanes and functionalized silsesquioxanes.
