The multifunctional phosphines containing several donor centers are able to form stable mono- or polynuclear transition metal complexes with various coordination modes. These types of cyclic ligands are widely utilized for the stabilization of large row transition metal cations to give the complexes with desired properties such as catalytic, luminescent, bioactive properties etc. The most common luminescent complexes of phosphines are copper(I), silver(I), gold(I), platinum(II), iridium(III) complexes. In the frame of the topic the some types of tunable cyclic phosphines and their behavior towards the copper(I) and gold(I) will be discussed. The synthesis of these phosphines was developed in Kazan several decades ago, while their application in the luminescent complexes design has been presented recently. The complexes based on these types of compounds display an attractive luminescence with the response to the presence of volatile organic compound or to the temperature changes. The topic will shed the light on the opportunities of the multifunctional cyclic phosphine ligands in the design of complexes with the tunable “stimuli-responsive” luminescence.
