Carboranos y sus derivados en el diseño de complejos de metales del grupo 11 emisores y precursores de nanopartículas de oror

Abstract

Se ha estudiado la reactividad de complejos oro y plata frente a ligandos C-dadores, fosfinas (closo o nido) y calcogenolatos derivados de carboranos, los estudios incluyen: -Complejos organometálicos [{Au(L)}2(µ-1,n-C2B10H10)] (n= 2, 7, 12), entre ellos los primeros de oro con para-carborano. A traves de calculos teóricos se compara la estabilidad de dichas especies. Se analiza el efecto de la coordinación a oro, del isómero de carborano y la monofosfina (L) en las emisiones. -Coordinación de la monofosfina [1-PPh2-2-Me-C2B10H11] y la nido-difosfina [7,8-(PPh2)2-C2B9H10]-. -Complejos de oro(III) [Au(ER)2{7,8-(PPh2)2C2B9H10}] y [Au(S-S){7,8-(PPh2)2C2B9H10}] (ER, S-S= calcogenolato) sintetizados a partir del derivado de oro(III) luminiscente [AuCl2{(PPh2)2C2B9H10}]. -El análisis de las propiedades emisoras por medio de cálculos teóricos DFT y TDDFT de [Au2{7,8-(PPh2)2C2B9H10}(C6F5)(PR3)] y [M{1,2-S2C2B10H10}{7,8-(PPh2)2C2B9H10}M'(PPh3)] con interacciones Au(I)···Au(I) o d8(M)···d10(M). -Los primeros ejemplos de complejos de oro(I) y oro(III) con ligandos [1,2-Se2-C2B10H10]2- y [1,2-Te2-C2B10H10]2-. -La síntesis de nanopartículas usando como precursores los complejos NBu4[Au(1,2-S2C2B10H10)2] y (NBu4)2[Au(7,8-S2C2B9H10)(1,2-S2C2B10H10)]
