Abstract

Conjugated poly(metalla-yne)s have attracted the interest of academic and industrial researchers working in the field of material chemistry. This review highlights advances made in the field of conjugated Pt(II) based poly-ynes. This include some basic aspects of conjugated Pt(II) poly-ynes; synthetic methodologies, structure-property relationships. Some examples of synthesizing non-platinum metalla-ynes are also included. In the application part, the major focus has been directed on the optoelectronic (OE) properties.

Keywords: Conjugated poly(metalla-ynes); Structure-property relationships; Pt(II) polynes; Optoelectronic applications
