Hydrazide complex offers semiconductor hope
06 February 2006
New and improved semiconductor materials could be on the horizon thanks to a breakthrough in organozinc complex synthesis.
Group 13 complexes containing ligands derived from hydrazines have attracted considerable attention as a potential source of semi-conducting materials. However, these types of materials involving other main group elements are extremely rare.
Carl Redshaw and Mark Elsegood at the University of East Anglia, UK, have made a novel tetrametallic zinc-nitrogen cage complex. The complex was further reacted with tertiary butyl lithium to give a chain-like structure comprising zinc-nitrogen cages linked via lithium centres. This type of structural motif has never been observed before.
'The challenge now is one of control,' said Redshaw. His group now aims to determine whether reagents can be selected to promote certain cage types and sizes. They believe that the improved conductivity resulting from the lack of hydrogen bonding in these materials will help develop new and improved semiconductors.
