Abstract
Here we report the NLO properties of the isomeric trans and cis forms of ra dical 1. This fact allowed us to prove the feasibility of polychlorotriphen ylmettzyl radicals as building blocks with electron acceptor ability for NL O materials. Moreover, by comparing the beta (vec) values obtained for isom ers trans-1 and cis-1 with those of related ferrocenyl-based chromophores, we propose that molecular torsions strongly decrease the second-order NLO r esponse.
