A novel cross-linked pyroelectric polymer with pronounced second-ordernonlinear optical properties has been prepared. A multistep synthesis with several selective transformations including a kinetic resolution (transesterification) with the highly enantioselective Candida antarctica lipase B, yielded the monomer 4‘‘-(R)-(−)-2-[(10-acryloyloxy)decyl]oxy}-3-nitrophenyl 4-4‘-[(11-acryloyloxy)undecyloxy]phenyl}

electronic properties of the aromatic PBO core than other possibilities. This particular combination gives luminophores that are suitable for optical applications on the basis of their high emission efficiency and photostability. In view of that, oriented films were prepared by in situ polymerization of a mixture of a liquid crystalline direactive matrix containing 5% (w/w) of the luminophore. The films
A facile synthesis of aryl esters is developed by coupling aryl carboxylicacids and aryl boronicacids in the presence of PhI(OAc)2 and carbonyl diimidazole. A wide range of functional groups were tolerant to the metal-free reaction condition that led to the desired products in good yields.
