Metal Complexes as Donor Groups

Since the pioneering work of Green et al. who, in 1987, reported a powder SHG efficiency 62 times that of urea for c/s-l-ferrocenyl-2-(4-nitrophenyl)ethylene, there has been considerable interest in using metallocenes as donor groups, and ferrocenyl compounds are amongst the most studied organometallic complexes for The ferrocenyl 

METAL-BASED QUADRATIC NONLINEAR OPTICAL MATERIALS 

The NLO properties of cyclopentadienyl metal alkynyl complexes have also proven an especially popular research topic, particularly those containing Group 8 metals. Most of the studies have involved
