(FR) LUMINESCENCE AVEC CONVERSION MOLÉCULAIRE ASCENDANTE DU PROCHE INFRAROUGE À LA LUMIÈRE VISIBLE
Abstract
(EN) The present invention relates to a self-assembled helical metallic complex of formula (1): [M1 M2M3(L1)3] (1) said metallic complex forming a triad donor (M1 )/acceptor (M2)/donor (M3), wherein the efficiency of the intermolecular energy transfer between the pair of donors (M \) and (M3) to the acceptor (M2) is from 30% to 70% and the L1 ligand- field strength of the donors (M1) and (M3) is at least 19000 cm-1.
(FR) Cette invention concerne un complexe métallique hélicoïdal auto-assemblé de formule (1) : [M1 M2M3(L1)3] (1) ledit complexe métallique formant une triade donneur (M1)/accepteur (M2)/donneur (M3). Le rendement du transfert d'énergie intermoléculaire entre la paire de donneurs (M1) et (M3) et l'accepteur (M2) est de 30 à 70 % et un ligand L1-champ de force des donneurs (M1) et (M3) est d'au moins 19000 cm-1.
