Acene-based compounds that can be used to prepare n-type semiconductor materials are provided with processes for preparing the same. Composites and electronic devices including n-type semiconductor materials prepared from these compounds also are provided.
The triple layered tetraazacyclophane 3a was prepared in high yield by a fourfold bond connection in a one-pot reaction sequence. The helical chirality of 3a results from the unique crossed meta/meta-cyclophane linkage. A racemisation process can only take place by breaking a covalent bond. The X-ray structure analysis of 3a proved the constitution of the isomer, difficult to determine by spectroscopy

The invention relates to a novel iron complex bearing a cyclic amine as ligand; and a process for the production of polymers by polymerizing a radical-polymerizable monomer in the presence of the iron complex and a radical generator. The invention aims at providing a process by which a polymer having a chemically convertible functional group at the end can be produced from a radical-polymerizable monomer and which permits the production of a block copolymer and a process for recovering, after polymerization, an iron complex into a solvent at a high recovery ratio. The aim can be solved by providing a novel iron complex, a process for producing a polymer in the presence of a radical polymerization initiator by using the iron complex as the polymerization catalyst, a process for the production of a block copolymer which is subsequent to the polymerization for producing the above polymer, and a process for recovering the iron complex easily and simply. The invention provides an iron complex useful in producing a polymer by polymerizing a radical-polymerizable monomer; and a process for the production of polymers with the iron catalyst.
The invention relates to novel linkers which comprise two or three basic, acidic or hydrophobic natural or non-natural amino acids. The invention also relates to drug conjugates comprising said linkers, to pharmaceutical compositions comprising said drug conjugates and to the use of said drug conjugates in preventing, suppressing or treating cancer.
