wherein
n is 1, 2, 3 or 4;
two of X, Y and Z are G1 group and G2 group, respectively, and the remaining one is selected from the group consisting of G1 group, G2 group and hydrogen; wherein
the G1 group, for each occurrence, is independently selected from —(CH2)m-L-(CH2)n—R1, wherein R1 is a coordination group, m is 1 to 6, n is 0 to 6, and L is a divalent group; and
the G2 group, for each occurrence, is independently selected from a C4-20 alkyl having a carbon chain with more than 4 carbon atoms.
