A G-quadruplex is a four-stranded DNA structure featuring stacked guanine tetrads, G-quartets. Formation of a G-quadruplex in telomere DNA can inhibit telomerase activity; therefore, development of G-quadruplex-ligands, which induce and/or stabilize G-quadruplexes, has become an area of great interest. Phthalocyanine derivatives have substantial potential as high-affinity G-quadruplex-ligands because these planar chromophores are similar in size and shape to the G-quartets. Here, we focus on the latest findings on phthalocyanine derivatives as G-quadruplex-ligands, and discuss the mechanisms by which phthalocyanines bind to G-quadruplexes with high affinity and selectivity. We also discuss potential biomedical and organic electronic applications of phthalocyanines that are dependent on their photophysical properties.
