Clustomesogens: Liquid Crystal Materials Containing Transition-Metal Clusters


  • We are grateful to UR1 and Fondation Langlois for financial support. We thank Cristelle Meriadec for X-ray measurements, Dr. V. Marchi-Artzner for access to the spectrofluorimeter, and Prof. D. Rondeau for HRMS measurements. Y.M. thanks Dr. M. A. Amela-Cortes for helpful discussions. This work was performed within the framework of the PHC Brancusi Program No. 19616UF.
