1. A method for preparing a macrocyclic metal cyanine, comprising the step of providing a macrocyclic metal-free cyanine compound
and inserting a metal therein using a metal reagent, wherein said metal reagent comprises at least one organic ligand, wherein
said organic ligand is acetylacetonate (acac), acetate or C1-8 alkoxide, and wherein the macrocyclic metal cyanine is of formula (I):
 Q1, Q2, Q3 and Q4 are the same or different and are independently selected from a C3-20 arylene group or a C3-20 heteroarylene group;
M is selected from Si(A1)(A2), Ge(A1)(A2), Ga(A1), Mg, Al(A1), TiO, Ti(A1)(A2), ZrO,
Zr(A1)(A2), VO, V(A1)(A2), Mn, Mn(A1), Fe, Fe(A1), Co, Ni, Cu, Zn, Sn, Sn(A1)(A2), Pb, Pb(A1)(A2), Pd and Pt;
A1 and A2 are axial ligands, which may be the same or different, and are selected from —OH, halogen, —OR3, a hydrophilic ligand and/or a ligand suitable for reducing cofacial interactions;
R3 is a selected from C1-12 alkyl, C5-12 aryl, C5-12 arylalkyl or Si(Rx)(RY)(Rz); and
Rx, Ry and Rz may be the same or different and are selected from C1-12 alkyl, C5-12 aryl, C5-12 arylalkyl, C1-12 alkoxy, C5-12 aryloxy or C5-12 arylalkoxy.
