Supramolecular gels, as a family of classical soft materials, have received considerable attention because of their wide potential applications in catalysis, chemical sensing, drug delivery carrier, and many other areas. Recently, it was found that the introduction of metal moieties, especially the transition metal moieties into the gelator allows for the additional scope for tuning gel properties such as catalytic activity, magnetism, and photo- and electrochemistry. Neutral platinum-acetylide complex have been investigated in many respects from supramolecular chemistry to materials science during the past two decades because of their attractive properties such as well-defined linear geometry, synthetic accessibility and intriguing photoproperties. In this review article, we summarize the recent results in the investigation of supramolecular organometallic gels based on neutral platinum-acetylide moieties. These systems are classified based on the skeleton of the gelator building blocks and divided into two main parts, conjugated phenylene cored platinum-acetylide derivatives as well as other platinum-acetylide derivatives containing various functional groups.
