Disclosed are branched PEG molecules, including branched PEG-lipids and branched-PEG proteins, as well as related compositions and methods for making branched PEG molecules. Also disclosed are related compositions, systems, and methods for in vivo delivery of therapeutic and diagnostic agents.
The present invention concerns functionalized photoreactive compounds of formula (I), that are particularly useful in materials for the alignment of liquid crystals. Due to the adjunction of an electron withdrawing group to specific molecular systems bearing an unsaturation directly attached to two unsaturated ring systems, exceptionally high photosensitivities, excellent alignment properties as well as good mechanical robustness could be achieved in materials comprising said functionalized photoreactive compounds of the invention.

A fluorocarboxylic acid-containing polymer comprising recurring units having formula (A1), but not acid labile group-containing recurring units is provided. A resist composition comprising the same offers a high sensitivity and is unsusceptible to nano-bridging or pattern collapse independent of whether it is of positive or negative tone.
